· 3 min read
Sessions of Monday, September 21 and Tuesday, September 22, 2026. A week after the Federal Reserve raised rates and the 10-year Treasury yield closed above 5%, the market took the Fed week back and then some. The S&P 500 rose 1.49%, the Nasdaq Composite 2.72% and the Dow 0.35% — and almost all of it happened on Monday.
The scorecard
| Close | Sept. 18 | Sept. 22 | Move |
|---|---|---|---|
| S&P 500 | 7,650.50 | 7,764.64 | +1.49% |
| Nasdaq | 26,522.54 | 27,244.28 | +2.72% |
| Dow | 51,682.64 | 51,863.69 | +0.35% |
| Russell 2000 | 2,860.40 | 2,889.92 | +1.03% |
| 10-year yield | 4.998% | 4.968% | −0.03 |
| VIX | 14.81 | 14.21 | −0.60 |
Year to date, the S&P 500 is up 13.4%, the Nasdaq 17.2% and the Dow 7.9%. Every close since, session by session, is listed on S&P 500 today, Nasdaq Composite today and Dow Jones today.
Monday did the work
Monday was the session. The S&P 500 rose 1.49%, the Nasdaq 2.26% and the Dow 0.71%. Tuesday added almost nothing: the S&P 500 closed unchanged to the second decimal, the Nasdaq added 0.45%, and the Dow gave back 0.36%. Two sessions, one of them real — worth remembering when a two-day move gets described as momentum.
The 10-year backed away from 5%
The 10-year Treasury yield closed at 4.968%, down from 4.998% on Friday and from the 5.006% print on September 16 that set the tone for the week before. In bond terms that is a small move. In mood terms it is not: 5% was the round number the market had been watching, and this rebound arrived with the yield sitting just under it rather than just above. Where it stands now, and every close before it, is on 10-year Treasury yield today.
What did the lifting
| Company | Sept. 18 → Sept. 22 |
|---|---|
| Meta (META) | +10.64% |
| Tesla (TSLA) | +4.02% |
| Nvidia (NVDA) | +2.97% |
| Broadcom (AVGO) | +1.94% |
| Apple (AAPL) | +1.08% |
| Microsoft (MSFT) | +0.85% |
| Amazon (AMZN) | +0.50% |
| Alphabet (GOOGL) | +0.46% |
Meta rose 10.64% over two sessions on its own. A handful of the largest technology companies did nearly all of the lifting, which is why the tech-heavy Nasdaq gained 2.72% while the Dow managed 0.35% — the same gap, in the same direction, as the week before. To see how the leaders compare, try Alphabet vs Meta or the Nvidia analysis.
What a bounce like this means for your portfolio
Two good sessions after a bad week feel like a recovery, and for the index they were one. Whether they were one for you depends on what you hold. A book leaning on the largest technology names took back more than the index did; one built on dividend payers, utilities or small caps took back less — and the headline number will not tell you which you own.
Is my portfolio actually diversified? walks through how to read your own weights, and the crash test carries the book you hold today through windows the market has already delivered, so you can see what it does when the two days go the other way.
