The last session was Tuesday, September 15. All three indices closed lower the day before the decision, with the S&P 500 down 0.45% at 7,585.51, the Nasdaq Composite down 0.78% and the Dow Jones Industrial down 0.63%. The pressure came from the bond market: the 10-year Treasury yield touched 5% on Monday, its highest since 2023. Today's stock in focus is Skyworks (SWKS), up 13.55% at $90.00, and what rose was a merger close to the finish line. The $22B combination with Qorvo is in its final stage and the company targets a close within 2026. August retail sales and import prices land at 12:30 UTC, and the real gate is the FOMC decision and dot plot at 18:00 UTC. Today's Academy is the Wednesday sector teardown: whose hands one card payment passes through. Data in this article is based on the September 15, 2026 US close, and all times are UTC.
Today's Market: All Three Indices Closed Lower the Day Before the Decision
All three indices closed lower on September 15. The Nasdaq Composite fell 0.78%, the weakest of the three; the Dow Jones Industrial fell 0.63%; the S&P 500 fell 0.45% to close at 7,585.51.
The pressure did not start in equities. It started in the bond market. The 10-year Treasury yield touched 5% on Monday, its highest since 2023. That date matters: it was Monday, September 14, not the previous session. The yield has not retreated far since, so valuations have spent the whole week sitting under that line.
The index moves also hide how far apart the sectors ran. On a sector-average basis across Nasdaq-listed companies, industrials fell 2.12% and utilities 1.80%, the two that led lower, while real estate rose 0.78% and energy 0.43%.
The two that led lower have something in common: both are among the most rate-sensitive groups there are. Industrials borrow to buy equipment, and the utility model is built on turning low-cost funding into steady cash flow. A yield at 5% lifts their discount rate and their funding cost at the same time.
August retail sales and import prices arrive at 12:30 UTC tonight, with the NAHB housing index and business inventories at 14:00 UTC. The weight of the day sits on the FOMC decision at 18:00 UTC, covered further below.
Stock in Focus, Skyworks (SWKS): What Rose Was a Merger Close to the Finish Line
Skyworks (SWKS) sells mobile radio frequency components within semiconductors and carries a market value of $13.5B. On September 15 it closed at $90.00, up 13.55%, adding about $1.62B of market value. Volume reached 12.94 million shares, 2.22x the 20-day average. The stock sits 2.5% below its 52-week high of $92.30.
Beta is 1.52, which means that when the market moves 1% this name moves about 1.5%. That figure returns later.
Why it rose: the $22B combination with Qorvo is in its final stage and the antitrust waiting period has expired. Combined revenue runs about $7.7B a year, with the company targeting $500M of cost savings over 24 to 36 months.
One qualifier here matters more than the gain itself.
The merger has not closed. On September 15 the company extended the exchange offers on two Qorvo bond series, with more than 90% already exchanged and management targeting a close within 2026.
Note what the act of extending an exchange offer tells you: it is evidence of work in progress, not evidence of completion. Whether bondholders tender, and when the exchange finishes, is what sets the timing of the close. So the line for this day is that the merger is in its final stage, not that it is done, and that the company targets a close within 2026, not that it will close within 2026. Timing and final terms remain subject to company announcements.
The five-dimension score fills in the character of the day, and it is the mirror image of the previous edition.
Four corners run almost to the edge: Trend Position 94, Relative Strength 100, Peer Ranking 100 and Valuation Temperature 99. The only reading in the middle band is Volatility Control at 59.
Set that against Tenable in the September 15 edition: 69, 100, 80, 40, 82, where four corners held up and Valuation Temperature at 40 was the single gap. That shape said expectation had moved out in front. Today's shape has no gap. It says something else: the strength of this day was bought with a wider swing. A beta of 1.52 is written into that row.
Peer Comparison: One Semiconductor Group, the RF Line Up and the AI Equipment Line Down
Put six semiconductor names from the same session side by side: Skyworks (SWKS) rose 13.55%, Qorvo (QRVO) 9.34%, Qualcomm (QCOM) 4.25% and onsemi (ON) 2.16%, while Lam Research (LRCX) fell 0.96% and Broadcom (AVGO) 1.58%. That leaves 15.13 points between the ends.
The four that rose all sit on the mobile radio frequency line, and the two that fell sit on the AI equipment line.
One figure here is easy to write up wrongly: the Nasdaq semiconductor group averaged −1.03% that day, and Skyworks finished 14.58 points ahead of it.
A stock up 13.55% against a group average of −1.03% reads like a name rising alone. Writing it that way would be wrong.
This was a group move, not a counter-move. Qorvo, Qualcomm and onsemi all rose in the same session, so the whole mobile radio frequency line was moving. The group average is negative because the AI equipment names carry more weight in that classification, and Broadcom and Lam pulled it down. A negative average is not the same as Skyworks rising alone.
The distinction is not pedantry. A group move says demand on this line is turning and one name is running at the front. A counter-move says the whole street fell and one name walked out on its own. What you watch next differs completely: the first asks whether demand on that line holds, the second asks whether the name's own story holds.
A supporting name, Transocean (RIG) at +8.99%, ran an unrelated line: a deepwater driller won an $80M two-well contract with drilling set for 2027, and the NYSE offshore drilling group averaged +4.96% the same day. It has nothing to do with semiconductors and should not be read alongside them.
One-Minute Concept: The Target's Price Does Not Move on Its Own
Skyworks rose 13.55% and Qorvo rose 9.34% in the same session. Two names rising together is not the puzzle. The puzzle is why the gap is that wide.
The answer does not need guessing. It can be derived.
In a stock-and-cash merger the target's price stops moving on its own from the day terms are signed. It follows the acquirer through a formula, and the formula sits in the deal terms.
The terms here: each Qorvo share converts into $32.50 in cash plus 0.960 Skyworks shares.
Step one, put the close into it. Skyworks closed at $90.00 on September 15:
32.50 + 0.960 x 90.00 = $118.90
Qorvo actually closed at $118.06, a gap of $0.84. Ahead of completion that gap is normal, and it reflects a small discount for whether the deal finishes on schedule.
Step two, the move follows too. Skyworks gained $10.74 on the day, so Qorvo should gain:
0.960 x 10.74 = $10.31
It gained $10.08, which lines up closely.
Step three, so why do the percentages differ by more than four points?
Because the $32.50 of cash is fixed and does not move with the share price. Part of Qorvo's price is anchored, and only the other part, 0.960 Skyworks shares, rises with the acquirer. Divide the same absolute gain by a larger base and the percentage comes out smaller.
A test you can carry to any deal: when you see an acquirer up A% and a target up B%, find the consideration formula in the terms before deciding whether that gap is normal. The higher the cash share, the blunter the target's percentage move. Where the actual move departs clearly from what the formula gives, that is the signal worth following, because the market is repricing how certain the close is.
⚠️ One qualifier is necessary: the formula holds only if the deal completes on its current terms. Amended terms, a delayed close or a termination all break it. So read it alongside where the transaction actually stands.
What to Watch Tonight: The Fed Decides, and the Four Rulers of Inflation Disagree
The FOMC decision lands at 18:00 UTC with the dot plot and the economic projections, followed by the chair's press conference at 18:30 UTC. Lennar (LEN) reports after the close.
This is the sixth policy meeting of the year and one of the four that carry a Summary of Economic Projections. Its place in the policy chain is as the anchor that prices the rate path:
The decision only answers whether rates move this once. The dot plot answers how many moves come after.
The policy range stands at 3.50% to 3.75% and has held through five consecutive meetings since the December 2025 cut.
The tension tonight is that the sentence "inflation has come down to here" depends on which ruler you pick up.
The four readings: headline CPI 3.4%, core CPI 2.4%, headline PCE 3.7%, core PCE 3.3%.
⚠️ One point of basis has to come first, or the whole section reads wrong: CPI is the August 2026 print and PCE is July, since August PCE is not published yet. They are one month apart and cannot be subtracted from each other. The four bars compare levels. They do not do arithmetic.
Set together, the conclusion is direct: three of the four rulers sit above 3%, and the only one below is core CPI at 2.4%, which happens to be the one quoted most often.
More to the point: the target the Fed writes down is set on PCE, not CPI. That is not habit, it is the official basis. So the line that core inflation has already fallen to 2.4% and is close to target carries limited weight at tonight's table, because the ruler the Fed itself targets now reads 3.3%.
There is a practical reason CPI gets quoted most: it is published first each month and the market reacts to it first. But the ruler seen first and the ruler the decision actually uses are not the same one, and that distance is what makes the press conference worth listening to.
Drill-Down: Where the 1.0 Point Between Headline 3.4% and Core 2.4% Sits
Take August CPI apart into five components, year over year: energy 16.3%, services excluding energy 3.0%, shelter 3.0%, food 2.7% and core goods 0.7%.
The 1.0 point between headline 3.4% and core 2.4% sits almost entirely in the two components core removes.
The mechanism is direct enough that people skip it: core CPI is defined as the basket with food and energy taken out. Energy ran 16.3% year over year, with gasoline inside it at 27.4%, and food ran 2.7%. Remove those two and the line left behind is naturally much lower.
So however hard the oil price runs it never enters core. It does enter the headline, and it also enters the fuel bill every month.
Look at the right-hand end as well: shelter at 3.0% and core goods at 0.7%. Shelter is about a third of the basket and moves slowly, which makes it the ballast of the headline print, while core goods sit close to zero. The bulk of the basket has gone quiet.
That is where tonight divides. Treat headline inflation as the bar and energy becomes a policy variable, and energy is set by geopolitical supply rather than by rates. Switch to core and 2.4% is already close to target. One dataset, two bars, two opposite paths.
Two specific things to watch.
First, read the dot plot median at 18:00 UTC. Whether rates move is secondary. The year-end and 2027 medians are what price how many moves come after, and that is where the curve actually follows.
Second, listen at 18:30 UTC for the basis. Does the chair treat headline inflation as the bar, or core? The two point to completely different paths, and that prices more than the decision itself.
Academy: Sector Teardown, Whose Hands One Card Payment Passes Through
Swipe a card for $100 in the US and the merchant hands over about $2.40.
Visa (V) keeps none of it, and that is stated in its own annual report.
Payments gets read as one sector, but a single swipe passes through five companies and none of them collects the same slice. Three questions take it apart.
First, ask where it stands in the flow of that payment.
Visa (V) | the network, which only lets money pass. It processed about 258 billion transactions last fiscal year on roughly $40B of net revenue, which is about $0.16 kept per transaction. Market value $701.3B.
PayPal (PYPL) | the step selected on the checkout page. It handled $486.4B last quarter across 439 million active accounts, on $8.68B of net revenue.
Global Payments (GPN) | collects and settles for merchants. Worldpay was folded in this January, and last quarter brought $3.32B of revenue at a 42.0% adjusted operating margin.
Toast (TOST) | sells the register into restaurants and then takes a cut of the card volume. About 180,000 locations last quarter, with roughly 9,500 net additions.
Shift4 (FOUR) | takes over ordering and payment for whole venues. It handled $61B last quarter, up 22% year over year.
Different positions collect different money. Visa collects a fee for passage, Global Payments collects for acquiring and settlement, Toast collects software plus a cut, and Shift4 collects for the whole system.
Second, ask how much of the revenue it reports is collected on someone else's behalf.
This is the step most often skipped, and Shift4 is the clearest example: gross revenue of $1.295B last quarter, and $624M once the network fees owed to card networks and issuers are stripped out. That leaves 48.2%, so more than half is money passing through.
That line is one the company breaks out itself. Several payments companies do, and where it is broken out, read that line. Reading gross revenue doubles the apparent size of the business.
Third, ask who pays when something goes wrong.
Visa states in its annual report that it issues no cards, lends nothing and carries no credit risk.
Shift4 states in its own filings that a chargeback a merchant cannot cover is its own loss.
One swipe, two very different risk positions. That difference never shows up in revenue, but it shows up somewhere else, which is the next section.
The Further Downstream, the Wider the Price Band
Put the one-year price band of the five side by side: Visa (V) 1.31x, Global Payments (GPN) 1.57x, Toast (TOST) 1.89x, PayPal (PYPL) 2.06x and Shift4 (FOUR) 2.56x.
⚠️ First, what this figure is: the one-year price band is the 52-week high divided by the 52-week low, and the unit is a multiple. It measures how far apart the high and the low sat over the year. It is not a return and it is not a valuation.
⚠️ It is also not the same metric as the 52-week range position used in the previous Academy, which is (price − low) ÷ (high − low) × 100 in percent and measures where today's price sits inside the range. The two sets of numbers must not be quoted against each other.
The ordering speaks for itself: the further downstream, the wider the band.
The link that only lets money pass is the steadiest. Visa's high and low sat 1.31x apart over the year. It issues no cards, lends nothing and carries no credit risk, and it collects a fixed share of passage, so its volume follows overall consumption rather than the fortunes of any one set of merchants.
Further downstream a company signs merchants one at a time and stands behind them. Shift4's high and low sat 2.56x apart, nearly twice Visa's. It takes over whole venues, and its customers are stadiums, hotels and restaurants, industries that swing more than consumption overall. On top of that, by its own filings, a chargeback a merchant cannot cover is its own loss.
The link that absorbs the risk is paid for the risk. The other half of that sentence is that good days and bad days both run sharper. The band is what measures it.
Company Profile: Shift4 (FOUR)
Shift4 deserves a section of its own because it pushes all three answers above to the same extreme.
It takes over the whole site. Ordering, payment and ticketing sit in one system, and the customers are stadiums, hotels and restaurants. It handled $61B last quarter, up 22% year over year. In the payment chain it stands at the end closest to both the consumer and the merchant.
Half of its revenue is not its own. Gross revenue was $1.295B last quarter and $624M after the network fees owed to card networks and issuers. That line is one the company breaks out itself, so it is not hidden. It is simply easy to skip.
Market value is $3.86B, the smallest of the five.
Put the three together and its position is clear: it stands at the far downstream end, half of the revenue it reports is money passing through, and when something goes wrong the loss is its own. All three point the same way, which is why it carries the most risk and also the widest price band, at 2.56x.
None of that says whether the company is good or bad. It says that Visa and Shift4 are not in the same business, even though both are called payments companies, and they should not be read with the same expectations.
A test you can carry to any name in the sector. The lesson closes like this: before you look at what a payments company sells, ask where it stands in the flow of one payment, how much of what it reports actually stays, and who pays when a customer fails. With those three answers you know what kind of swing to expect from it.
Frequently Asked Questions
Q: Skyworks (SWKS) rose 13.55% on September 15 while the group averaged −1.03%. Can that be written as a name rising alone against the market?
A: No. Qorvo (QRVO) rose 9.34%, Qualcomm (QCOM) 4.25% and onsemi (ON) 2.16% in the same session, so the whole mobile radio frequency line was moving. This was a group move. The average is negative because the AI equipment names, Broadcom at −1.58% and Lam Research at −0.96%, carry more weight in that classification. A negative average is not the same as one name rising alone.
Q: Has the Skyworks and Qorvo merger completed?
A: No. It is in its final stage and the antitrust waiting period has expired, but it has not closed. On September 15 the company extended the exchange offers on two Qorvo bond series, with more than 90% already exchanged, and management targets a close within 2026. Extending an exchange offer is itself evidence of work in progress. Timing and final terms remain subject to company announcements.
Q: Why did Skyworks rise 13.55% while Qorvo rose only 9.34%?
A: Because part of the consideration is fixed cash. The terms are $32.50 in cash plus 0.960 Skyworks shares per Qorvo share. In absolute terms the two do line up: Skyworks gained $10.74, so Qorvo should gain 0.960 x 10.74 = $10.31, and it gained $10.08. But that $32.50 does not move with the share price, so in percentage terms it dilutes the gain.
Q: Four of the five dimensions score above 94. Does that mean there is no risk here?
A: No. Volatility Control at 59 is the one reading in the middle band, and it corresponds to a beta of 1.52: when the market moves 1%, this name moves about 1.5%. The shape is not pointing at a gap. It says four full corners were bought with a wider swing, and that row should not be lost behind the other four.
Q: Core CPI has fallen to 2.4%. Is that close to the Fed's target?
A: The line skips one change of basis. The target the Fed writes down is set on PCE, not CPI. Three of the four rulers sit above 3%: headline CPI 3.4%, headline PCE 3.7% and core PCE 3.3%. Only core CPI reads 2.4%, and it happens to be the one quoted most often. CPI is simply the measure published first each month.
Q: Can the CPI and PCE figures on the chart be subtracted from each other?
A: No. CPI is the August 2026 print and PCE is July, since August PCE is not published yet, so they are one month apart. The four bars compare levels and do not do arithmetic.
Q: Is the one-year price band the same as 52-week range position?
A: No, they are different metrics. The one-year price band is the 52-week high divided by the 52-week low, and the unit is a multiple, measuring how far apart the high and the low sat. The 52-week range position used in the previous Academy is (price − low) ÷ (high − low) × 100 in percent, measuring where today's price sits inside the range. The two sets of numbers must not be quoted against each other.
Q: Can Shift4's $1.295B of quarterly revenue be compared directly with other payments companies?
A: Carefully. That $1.295B is gross revenue, and $624M remains once the network fees owed to card networks and issuers are stripped out, a retention of 48.2%. The company breaks that line out itself, so read that line where it is given. Comparing on gross revenue doubles the apparent size of the business.
