Gamma Risk

What Is Gamma Risk?

Gamma risk is the risk that an options position’s directional exposure will change rapidly when the price of the underlying cryptocurrency moves.

Gamma measures how much an option’s delta is expected to change for a specified change in the underlying asset’s price.

Because delta estimates an option’s sensitivity to price movement, gamma describes how quickly that sensitivity itself can increase or decrease.

A position with high gamma can shift from having limited directional exposure to having substantial exposure after a relatively small movement in Bitcoin, Ether, or another crypto asset.

Gamma risk is especially important for traders who sell options, maintain delta-neutral portfolios, provide liquidity, or manage large books of crypto derivatives.

It becomes more intense when an option is near its strike price and close to expiration.

Crypto volatility, continuous trading, limited liquidity, price jumps, and weekend market activity can make gamma risk harder to manage than a simple mathematical estimate may suggest.

Gamma is one of the option Greeks, which are measurements used to estimate how option values and risks respond to changes in market conditions.

The Options Industry Council’s guide to option Greeks explains that Greeks are theoretical guideposts rather than guarantees of exact price changes.

What Is Gamma?

Gamma is the rate at which an option’s delta changes as the underlying cryptocurrency price changes.

In mathematical form, gamma can be written as

.

Gamma is also the second derivative of the option’s theoretical value with respect to the underlying asset’s price.

This relationship can be written as

.

The official gamma education page describes gamma as the expected change in delta following a one-unit movement in the underlying asset.

Some crypto options systems display gamma per one-dollar price move, while others scale it for a one-percent move or another standard interval.

Traders must confirm the unit used by their analytics platform before calculating hedge adjustments.

A raw gamma value without its contract size, price unit, and settlement structure can be misleading.

What Is Delta?

Delta estimates how much an option’s value may change when the underlying cryptocurrency price changes by one unit.

A call option usually has a positive delta because its value generally rises when the underlying asset rises.

A put option usually has a negative delta because its value generally rises when the underlying asset falls.

A call with a delta of 0.50 may gain approximately $0.50 for an initial $1 increase in the underlying asset, assuming other pricing factors remain unchanged.

That estimate is only local because delta changes as the asset price, time to expiration, and implied volatility change.

Gamma measures this change in delta and therefore reveals the curvature that a fixed-delta estimate misses.

How Gamma Changes Delta

A simple gamma approximation is

.

Suppose a Bitcoin call has a delta of 0.50 and gamma of 0.00004 per one-dollar price movement.

If Bitcoin rises by $1,000, the call’s delta may increase by approximately 0.04 to 0.54.

If Bitcoin falls by $1,000, the call’s delta may decrease by approximately 0.04 to 0.46.

This calculation is an approximation because gamma itself changes as the underlying price moves.

A large price movement should be analyzed with a complete pricing model or scenario simulation rather than one fixed gamma value.

Contract multipliers must also be included when the option represents more or less than one unit of the underlying cryptocurrency.

Why Gamma Risk Is Nonlinear

A linear risk changes at a roughly constant rate, while gamma creates a curved relationship between the option’s value and the underlying price.

A fixed delta estimate assumes that the option keeps the same directional sensitivity throughout a price movement.

In reality, a long call usually becomes more sensitive as the underlying asset rises toward or above its strike.

A long put usually becomes more negatively sensitive as the underlying asset falls toward or below its strike.

This changing exposure means that losses or gains can accelerate rather than grow at a constant rate.

For a small underlying movement, the gamma contribution to the option’s price change can be approximated with

.

The squared price-change term shows why gamma becomes more important during large crypto movements.

Long Gamma

A trader is generally long gamma when holding a standard call or put option.

Long gamma causes the position’s delta to change in a direction that benefits continued movement in the underlying asset.

A long call gains more positive delta as the cryptocurrency rises and loses positive delta as the cryptocurrency falls.

A long put gains more negative delta as the cryptocurrency falls and becomes less negative as the cryptocurrency rises.

This convex behavior limits the option buyer’s loss to the premium paid while allowing larger gains when the market makes a sufficiently strong favorable move.

Long gamma is not automatically profitable because the buyer must overcome the option premium, time decay, volatility changes, transaction costs, and execution slippage.

A crypto asset can remain stable while the option loses value each day even though the position has positive gamma.

Short Gamma

A trader is generally short gamma after selling a standard call or put option.

Short gamma causes delta to change in a direction that can make an adverse price movement increasingly damaging.

A short call becomes more negatively exposed as the underlying cryptocurrency rises.

A short put becomes more positively exposed as the underlying cryptocurrency falls because the seller’s losses increase as the asset declines.

A delta-neutral short-gamma position tends to become short after the market rises and long after the market falls.

Maintaining neutrality may therefore require buying after prices rise and selling after prices fall.

This unfavorable rebalancing pattern is a central source of gamma risk for option writers and market makers.

An uncovered short option can create losses substantially larger than the premium originally received.

Positive Gamma vs. Negative Gamma

Positive gamma means that the position benefits from convexity and becomes more directionally aligned with large price movements.

Negative gamma means that the position’s directional exposure becomes less favorable as the market moves against it.

Long calls and long puts normally have positive gamma.

Short calls and short puts normally have negative gamma.

A multi-leg crypto options strategy can have positive, negative, or nearly neutral net gamma depending on the strikes, expirations, quantities, and option types involved.

The risk of a spread must be evaluated from the combined Greeks of all its legs rather than from one option in isolation.

The guidance on net option Greek exposure explains that a spread behaves according to the combined delta, gamma, theta, and vega of its components.

When Is Gamma Risk Highest?

Gamma is generally highest when an option is close to the money and near expiration.

An at-the-money option has an underlying price close to its strike price.

Near expiration, a small price movement can rapidly change whether the option is likely to finish in the money or out of the money.

Its delta can therefore move sharply toward one, zero, or negative one over a short period.

Deep in-the-money and far out-of-the-money options usually have lower gamma because their deltas are already closer to their limiting values.

Gamma can become extremely concentrated around one strike during the final hours or minutes before expiration.

Crypto traders should remember that significant price movement can occur at any hour because the underlying spot market commonly operates continuously.

Gamma Risk Near Expiration

Short-dated crypto options can appear inexpensive while carrying intense gamma exposure.

An option with only a few hours remaining has little time for a price movement to be reversed before settlement.

A small move across the strike can change the option’s delta rapidly and alter the required hedge.

The option seller may need to rebalance repeatedly during a volatile expiration period.

Low liquidity can make those hedge trades expensive or impossible at the theoretical price.

Expiration risk also depends on the settlement time, settlement index, exercise method, contract multiplier, and settlement currency.

Traders should not assume that every crypto option expires or settles under identical rules.

Gamma Risk in Volatile Crypto Markets

Cryptocurrency prices can move rapidly in response to macroeconomic news, regulatory developments, security incidents, protocol changes, liquidations, and shifts in market sentiment.

A large move can make an earlier delta estimate outdated within seconds.

The hedge required before the movement may be far too small after the movement.

The CFTC advisory on virtual currency trading risks warns that crypto spot, futures, and options markets can involve significant volatility and speculation.

Gamma models normally describe smooth changes around the current price, but real crypto markets can jump between price levels.

A sudden gap can prevent a trader from rebalancing at the intermediate prices assumed by a continuous model.

This difference between modeled adjustment and available execution is known as gap risk or jump risk.

Gamma Risk and Delta Hedging

Delta hedging attempts to offset an option position’s directional exposure by trading the underlying asset or another closely related instrument.

A trader with a positive delta may sell some underlying cryptocurrency to reduce the portfolio’s net delta.

A trader with a negative delta may buy the underlying asset to move the portfolio closer to neutral.

Gamma causes the hedge ratio to change whenever the underlying price changes.

A portfolio that is delta-neutral now may no longer be neutral after the cryptocurrency moves.

High-gamma positions require more frequent or larger hedge adjustments than low-gamma positions.

Every adjustment creates possible trading fees, spreads, slippage, funding costs, and operational risk.

Delta hedging reduces local directional risk but does not remove gamma, vega, theta, liquidity, basis, or settlement risk.

Example of Short-Gamma Hedging

Assume a trader sells crypto calls and initially hedges the position to zero delta.

If the underlying asset rises, the short calls develop a larger negative delta.

The trader must buy more of the underlying cryptocurrency to restore the hedge.

If the asset then falls, the options lose some negative delta and the hedge becomes excessively long.

The trader must sell part of the cryptocurrency at the lower price.

Repeated price reversals can therefore force the short-gamma trader to buy high and sell low.

The option premium and time decay must be large enough to compensate for these hedge losses and other costs.

Gamma Scalping

Gamma scalping is a strategy that combines a long-gamma options position with repeated delta hedging.

The trader buys the underlying asset after a decline and sells it after a rise to keep the portfolio near delta-neutral.

This rebalancing pattern can capture gains from realized price movement.

The strategy is profitable only when the captured movement is sufficient to overcome the cost of the options, time decay, spreads, fees, and imperfect execution.

A long-gamma position can lose money when realized volatility is lower than the volatility implied by the option price.

Gamma scalping also requires reliable liquidity and continuous operational capability.

Unexpected price jumps can produce favorable convexity for a long-gamma trader, but the subsequent hedge may still execute at a poor price.

Gamma Risk and Theta

Gamma and theta often create a trade-off between movement exposure and time decay.

A long option usually has positive gamma and negative theta.

This means the holder can benefit from large movement but generally loses theoretical value as time passes with other factors unchanged.

A short option usually has negative gamma and positive theta.

The seller may earn value from time decay while accepting the risk of accelerating losses during a strong price movement.

High gamma near expiration is often accompanied by rapid theta decay.

A trader should not evaluate gamma without considering how much premium is being lost or earned over time.

Gamma Risk and Implied Volatility

Implied volatility is the level of future movement reflected in an option’s market price.

Gamma and implied volatility interact because volatility affects the range of prices the model considers plausible before expiration.

For an at-the-money option, lower implied volatility can concentrate the transition in delta around the strike and increase gamma.

Higher implied volatility can spread delta changes across a wider price range.

The relationship differs for in-the-money and out-of-the-money options, so one simple statement does not describe every contract.

The option volatility and Greeks guide explains how gamma, delta, theta, and vega respond to changing pricing conditions.

A crypto options book can lose money from a volatility decline even when its gamma position was designed for price movement.

Gamma Risk and Vega

Vega estimates how much an option’s value changes when implied volatility changes.

A long option is usually positive gamma and positive vega.

A short option is usually negative gamma and negative vega.

A volatility increase can therefore benefit many long-gamma positions while harming many short-gamma positions.

However, gamma and vega do not move in a fixed one-to-one relationship across strikes and expirations.

A trader can construct spreads that hold substantial gamma but limited net vega, or substantial vega but lower near-term gamma.

Complete risk analysis should measure both exposures separately.

Gamma Risk and Crypto Price Jumps

Option models often assume that prices change continuously, but crypto markets can move through several price levels without sufficient liquidity at each level.

A hacking report, liquidation cascade, stable-value asset disruption, or sudden policy announcement can produce a large jump.

A short-gamma trader may be unable to buy or sell the hedge before the market has already moved far beyond the planned adjustment level.

The resulting loss can be much greater than the loss predicted by a small-movement gamma estimate.

Stop orders also may execute far from their trigger prices during a rapid move.

Scenario analysis should therefore include discrete jumps rather than only gradual one-percent changes.

Gamma Risk and 24/7 Crypto Trading

Crypto spot markets commonly remain active during nights, weekends, and public holidays.

An options position can continue changing risk while the trader is asleep or while related financial markets are closed.

The underlying crypto asset may move while a preferred hedge instrument is unavailable or less liquid.

Weekend order books can also be thinner, increasing spreads and price impact.

Automated hedging systems can reduce response time but introduce software, connectivity, API, and execution risks.

A trader managing negative gamma must plan for continuous price exposure rather than assuming that risk stops at the end of a traditional session.

Gamma Risk and Liquidity

Theoretical gamma assumes that the trader can observe prices and adjust the hedge as required.

Real execution depends on available liquidity.

A thin order book may cause a hedge transaction to move the market and create substantial slippage.

Option markets can also have wide bid-ask spreads, especially for distant strikes or unusual expiration dates.

A model may report a profitable hedge adjustment while the executable market price produces a loss.

Large traders must consider market depth rather than only the best displayed bid or ask.

Liquidity can disappear during the exact volatility event in which gamma risk becomes most important.

Gamma Risk and Leverage

Options provide nonlinear exposure while requiring only the premium or margin specified by the contract.

This structure can create substantial effective leverage.

A short option may collect a relatively small premium while creating a much larger possible loss.

As gamma changes the position’s delta, the required margin and hedge size can rise rapidly.

A trader may be forced to close positions during unfavorable market conditions when collateral becomes insufficient.

Crypto collateral can also fall in value at the same time that the derivative position produces a loss.

This wrong-way relationship can accelerate liquidation risk.

Gamma Risk and Margin

Margin is collateral required to support a leveraged or short derivatives position.

Risk systems may increase margin requirements when volatility rises, expiration approaches, liquidity falls, or a position becomes more concentrated.

A short-gamma trader can therefore face both a trading loss and a larger collateral requirement during the same market movement.

Portfolio margin may recognize offsetting positions, but the offset can weaken when strikes, expirations, assets, or settlement methods differ.

A hedge that appears effective under normal conditions may receive less margin benefit during stress.

Traders should calculate available collateral under severe upward and downward price scenarios.

Gamma Risk in Calls

A long call normally has positive gamma.

Its delta becomes more positive as the underlying cryptocurrency rises and less positive as the cryptocurrency falls.

A short call normally has negative gamma.

Its loss sensitivity increases as the asset rises, particularly when the call moves through its strike near expiration.

An uncovered short call can have theoretically unlimited loss in cash terms because the underlying asset has no fixed maximum price.

A call spread can limit the maximum loss by purchasing another call at a higher strike, although the combined position still has changing gamma.

Gamma Risk in Puts

A long put normally has positive gamma and negative delta.

Its delta becomes more negative as the underlying cryptocurrency falls.

A short put normally has negative gamma and positive directional exposure to the asset.

Its loss can accelerate when the cryptocurrency declines through the strike.

A cash-secured short put reduces funding uncertainty by reserving enough assets to satisfy the possible purchase obligation, but it does not remove market loss.

A put spread can cap downside risk by purchasing a lower-strike put, although the position’s net gamma changes as price moves between the strikes.

Gamma Risk in Option Spreads

A vertical spread combines options with the same expiration but different strike prices.

A calendar spread combines options with different expiration dates.

A butterfly or condor combines several strikes to create concentrated payoff regions.

Each structure has a net gamma profile that can change sign as the underlying asset moves.

A spread described as limited risk can still experience rapid changes in delta near one of its short strikes.

Calendar spreads can carry competing gamma and vega exposures because the near-term and longer-term options respond differently.

Traders should graph net gamma across a wide range of possible crypto prices instead of examining only the current value.

Gamma Risk in Crypto Option Settlement

Crypto options may use cash settlement, cryptocurrency settlement, stable-value settlement, or another contract-specific method.

The option may also be quoted in one asset while its profit and loss are paid in another.

Inverse or coin-denominated contracts can create nonlinear exposure between the option value and the collateral asset.

A trader may therefore face gamma risk from the option and additional value changes from the settlement currency.

Settlement-index construction can also create basis risk when the index differs from the market used for hedging.

Every gamma calculation should use the contract multiplier, quote convention, settlement asset, and exercise rules of the actual option.

What Is Portfolio Gamma?

Portfolio gamma is the combined gamma exposure of all options in a portfolio.

Each position’s gamma must be adjusted for quantity, contract multiplier, direction, and unit convention before aggregation.

Positive and negative gamma positions can offset at the current market price.

The offset may disappear after the asset moves because each option’s gamma changes differently.

Options on different crypto assets should not be treated as perfect offsets because their prices can separate during stress.

Even options on the same asset can create basis risk when they use different settlement indices or collateral rules.

Portfolio gamma should be evaluated across several price and volatility scenarios rather than as one current number.

What Is Gamma Exposure?

Gamma exposure is an estimate of how much a position’s delta may change when the underlying cryptocurrency moves.

It is sometimes abbreviated as GEX.

A portfolio with positive gamma exposure generally requires selling into rises and buying into declines to remain delta-neutral.

A portfolio with negative gamma exposure generally requires buying into rises and selling into declines.

Public market-wide gamma exposure estimates often rely on assumptions about whether traders or liquidity providers hold the long or short side of open contracts.

Those assumptions may be inaccurate because public data does not always reveal the complete owner, hedge, or related over-the-counter position.

Crypto gamma estimates can be especially incomplete when activity is divided among several markets, on-chain systems, bilateral agreements, and different settlement products.

Can Gamma Exposure Affect Crypto Prices?

Large options positions can influence short-term market behavior when traders hedge their changing delta by buying or selling the underlying cryptocurrency.

Positive-gamma hedging can reduce movement because the hedger tends to sell after a rise and buy after a decline.

Negative-gamma hedging can amplify movement because the hedger tends to buy after a rise and sell after a decline.

This effect depends on the size of the positions relative to available market liquidity.

It also depends on whether the assumed position holders are actually hedging and whether they use the same underlying market.

Gamma exposure should therefore be treated as one possible source of order flow rather than a complete explanation of every crypto price movement.

What Is a Gamma Squeeze?

A gamma squeeze is a rapid price movement that may be strengthened by option-related hedging activity.

For example, strong demand for calls can leave option sellers with negative gamma and increasing negative delta as the underlying crypto asset rises.

Those sellers may buy more of the underlying asset to hedge their exposure.

The additional buying can contribute to further price increases and require even more hedging.

The process can also operate in the opposite direction when put-related hedging adds selling pressure during a decline.

Not every sharp crypto movement is a gamma squeeze because spot demand, liquidations, leverage, news, and market manipulation can produce similar price behavior.

Public option data alone rarely proves the exact cause of a movement.

How to Measure Gamma Risk

A trader should begin by confirming the gamma unit, contract multiplier, settlement currency, and sign of every position.

The next step is to calculate net delta and net gamma at the current underlying price.

The trader should then reprice the portfolio across several possible upward and downward movements.

Useful scenarios may include ordinary daily moves, historical stress events, overnight jumps, and moves beyond major option strikes.

Time should also be advanced because gamma can increase rapidly as expiration approaches.

Implied volatility should be changed independently to reveal interaction with vega.

Transaction costs and available order-book depth should be applied to each required hedge.

A complete stress test should include collateral losses, changing margin requirements, basis movement, and possible inability to trade.

How to Manage Gamma Risk

Gamma risk can be reduced by closing part of a short-option position or purchasing options with positive gamma.

A trader can use defined-risk spreads instead of uncovered short options to limit possible losses.

Position sizes can be reduced as expiration approaches and gamma becomes more concentrated.

Strikes can be diversified so that the entire portfolio does not depend on one narrow price level.

Delta can be rebalanced according to predetermined risk limits rather than emotional reactions to market movement.

Sufficient collateral and liquid reserves should remain available for adverse price changes and margin increases.

Automated hedging systems should include price limits, maximum order sizes, connection monitoring, and emergency shutdown procedures.

No hedging process completely removes gamma risk because markets can jump before an adjustment is completed.

Common Gamma Risk Mistakes

A common mistake is treating delta as a fixed exposure and ignoring how quickly it can change.

Another mistake is selling short-dated options because their premiums appear easy to collect without recognizing their concentrated gamma.

Traders may calculate gamma for one contract but forget to multiply it by the number of contracts and the contract size.

They may also use a per-dollar gamma as though it were a per-percent gamma.

Another mistake is assuming that a delta-neutral portfolio is risk-free.

Delta neutrality describes current local exposure and can disappear immediately after the underlying asset moves.

Traders may also ignore liquidity and assume that every theoretical hedge can be executed at the displayed price.

The most dangerous mistake is combining negative gamma with excessive leverage and insufficient collateral.

Gamma Risk and Model Limitations

Gamma is calculated from an options pricing model and depends on the model’s assumptions and inputs.

Different models can produce different gamma values for the same crypto option.

Implied volatility surfaces, interest rates, funding conditions, settlement conventions, and price-distribution assumptions all affect the result.

Traditional models may not fully capture crypto price jumps, changing liquidity, fragmented markets, or unstable correlations.

A model can estimate risk under defined conditions but cannot guarantee actual profit, loss, or hedge performance.

The Greeks should therefore be combined with scenario analysis, execution data, and conservative risk limits.

Gamma Risk for Crypto Option Buyers

Option buyers generally benefit from positive gamma because large favorable movements can increase their directional exposure.

The buyer’s maximum direct loss is normally limited to the premium paid when the option is fully funded and no additional leveraged position is involved.

However, positive gamma does not guarantee a profit.

The option can expire worthless when the underlying asset does not move far enough.

Time decay can reduce the premium every day, while a decline in implied volatility can lower the option’s value even after a favorable price movement.

Wide spreads can also make it expensive to close the position before expiration.

Gamma Risk for Crypto Option Sellers

Option sellers generally accept negative gamma in return for receiving premium and positive time decay.

Their losses can accelerate when the underlying cryptocurrency moves strongly through the option’s strike.

Frequent delta hedging can reduce directional exposure but may create repeated buy-high and sell-low transactions.

A price gap can create a large loss before the hedge can be adjusted.

Margin requirements may increase at the same time that the position loses value.

Short-option traders should understand the maximum loss, liquidation process, collateral behavior, and settlement obligations before opening the position.

Gamma Risk and Smart Contracts

On-chain options and structured crypto products may calculate payouts through smart contracts.

Smart contract automation does not remove gamma risk from the economic position.

The contract may execute correctly while the option seller still experiences a large market loss.

On-chain hedging may also involve network fees, transaction delays, oracle updates, block ordering, and liquidity-pool price impact.

An oracle delay can cause the hedge or settlement reference to differ from a rapidly changing spot market.

Smart contract risk, oracle risk, and gamma risk should be assessed separately.

Gamma Risk and Expiration Pinning

Expiration pinning describes a situation in which an underlying price remains near a heavily traded option strike as expiration approaches.

Hedging by positive-gamma participants can sometimes contribute to stabilizing activity around a strike.

However, the same area can become unstable when negative-gamma exposure dominates or liquidity suddenly decreases.

A price that appears pinned can break away sharply when new spot demand, liquidations, or news overwhelms the hedging flow.

Open interest near a strike does not reveal every participant’s direction or hedge.

Pinning should therefore be treated as a possible market behavior rather than a guaranteed expiration outcome.

Does high gamma guarantee a profit?

No, time decay, option premium, implied volatility changes, fees, spreads, and incorrect market direction can still produce a loss.

Why is crypto gamma risk significant?

Crypto assets can trade continuously, move rapidly, experience price jumps, and become less liquid during stressful market conditions.

Can gamma be hedged?

Gamma can be reduced by changing option positions, but trading the underlying asset hedges delta rather than permanently removing gamma.

How does theta relate to gamma?

Long-gamma positions usually pay time decay, while short-gamma positions usually earn time decay in exchange for nonlinear movement risk.

How does implied volatility affect gamma?

Implied volatility changes how delta is distributed across possible future prices and can increase or decrease gamma depending on strike and moneyness.

What is portfolio gamma?

Portfolio gamma is the combined gamma exposure of every option position after accounting for direction, quantity, and contract size.

What is gamma exposure or GEX?

Gamma exposure is an estimate of how much a position or group of positions may change delta as the underlying asset moves.

Are public crypto GEX estimates exact?

No, they often depend on incomplete position data and assumptions about who owns, sold, or hedged the options.

Can gamma risk cause liquidation?

Yes, rapidly increasing losses and margin requirements can liquidate an undercollateralized short-gamma position.

Does a defined-risk spread remove gamma?

No, it limits possible loss but still has net gamma that changes with price and time.

Can smart contracts remove gamma risk?

No, automation can enforce the option terms but cannot remove the economic risk created by changing crypto prices.

What is the main danger of short gamma?

The main danger is that losses and hedge requirements can accelerate during a strong or sudden market movement.

Conclusion

Gamma risk is the nonlinear risk created when an option’s delta changes as the underlying cryptocurrency price moves.

It is most concentrated in options that are near their strike prices and close to expiration.

Long options generally have positive gamma, while short options generally have negative gamma.

Positive gamma can benefit from sufficiently large realized movement but usually carries premium cost and negative time decay.

Negative gamma can earn option premium and time decay but may create accelerating losses during a strong crypto movement.

A delta-neutral portfolio can still carry substantial gamma risk because its directional exposure changes after every price move.

Continuous crypto trading, price jumps, fragmented liquidity, leverage, changing collateral values, and settlement differences can make practical gamma risk greater than a simple model suggests.

Traders should evaluate gamma together with delta, theta, vega, margin, liquidity, basis, and smart contract risk.

Effective management requires position limits, scenario testing, sufficient collateral, realistic hedge costs, and a clear understanding of each option’s contract specifications.

Gamma is most useful as a dynamic risk measurement rather than a prediction that guarantees a particular option price or trading result.
