Market Snapshot β September 23, 2026 (4:17 PM ET, post-close)
| Index | Level | Change |
|---|---|---|
| S&P 500 | 7,706.03 | β0.75% |
| NASDAQ | 26,936.037 | β1.13% |
| Dow Jones | 51,511.59 | β0.68% |
| VIX | 15.19 | +6.90% |
A hot services PMI did all the damage today. The print pushed the 10-year Treasury yield back above 5%, and that single move repriced the October Fed meeting, lifted the dollar, and knocked the goldilocks trade off the table. The S&P 500 slid 0.75% to 7,706.03, the NASDAQ fell 1.13% to 26,936.037, and the Dow gave back 352 points to close at 51,511.59. Volatility woke up too β the VIX jumped 6.90% to 15.19, its biggest one-day move in either direction this week. Oil complicated matters further: crude rallied on a global diesel shortage narrative even after an unexpected 3-million-barrel build in U.S. crude stockpiles, and gold broke below $4,300 as traders bet on a hawkish Fed.
Against that backdrop, here's the remarkable part: not a single semiconductor on our board flipped. The perfect-5 formation broke yesterday, but the 4 Bulls / 1 Bear board survived its first real stress test. Four of five chips closed red β some of them down more than 2% β and every bullish SAR level held with room to spare. The lone bear, NVDA, actually saw its flip wall get further away, not closer. On a day like this, that's the story: the technical structure of this sector is sturdier than the macro tape hitting it.

Board: 4 Bulls / 1 Bear (unchanged). Post-market drift as of ~4:17 PM ET: NVDA $225.389, MU $1,069.36, AMD $613.9225, INTC $122.35, AVGO $354.9988 β no damage done in after-hours.
New flips today: NONE. β‘ Near-flip watch: NVDA is the only name within 3% of its SAR, at +2.59% β and that gap widened from +1.29% yesterday.
Close: $225.51 | β1.47% | Flip at $231.35 (+2.59%)
Six days of gains ended today as the yield surge hit the most crowded AI trade first. But look at the SAR mechanics: the bearish dot dropped from $231.81 to $231.35 while price slid from $228.87 to $225.51 β the SAR is decaying faster than the stock is falling, so the flip wall widened from 1.29% to 2.59%. NVDA needs to close above $231.35 (a +$5.84 move) to flip bullish. Headwinds today were both technical and narrative: a Barron's piece on the "Google TPU conundrum" resurfaced custom-silicon fears, and a director sale of ~$300.15 million on September 18 added supply optics. The setup remains the same as yesterday β a coiled spring just under the flip line β but the cushion for the bearish signal has doubled. Watch $231.35 tomorrow; it's the single most important number on this board.
Close: $354.99 | β2.62% | Flip at $336.43 (β5.23%)
The board's newest bull β it flipped just yesterday β absorbed the worst loss of the group, dropping 2.62% from $364.54 to $354.99, and its SAR support still sits 5.23% below. That's the thinnest buffer among the four bulls, which is normal for a Day-2 signal where the SAR hasn't had time to climb. The fundamental tape actually helped: Anthropic is reportedly in early talks to lease up to 1 gigawatt of data-center capacity that would house Broadcom, Google, and Nvidia chips. AVGO closed at the day's low, though, so this is the bull to watch most closely if the yield-driven pressure extends into tomorrow.
Close: $614.61 | β1.47% | Flip at $512.86 (β16.55%)
AMD's 12-day uptrend shrugged off the macro hit with a mild 1.47% fade from $623.77, and its SAR climbed meaningfully from $494.69 to $512.86 β the biggest one-day SAR advance on the board, because the stock keeps printing higher prices. The flip wall at $512.86 now sits 16.55% below the close. The narrative side is heating up too: CEO Lisa Su confirmed she'll attend Thursday's TrumpβXi state dinner alongside Jensen Huang, Tim Cook, and Elon Musk β a seat at the table where AI chip export policy could get discussed. Social sentiment remains the most bullish of the group at +52, though retail chatter is starting to debate whether the run from the $456 area to $614 is overheated. The SAR says the trend is intact; discipline says respect the $512.86 line.
Close: $122.60 | β1.02% | Flip at $101.00 (β17.62%)
The best relative performance of the day belonged to the board's longest-running bull. INTC slipped just 1.02% and held above $122, keeping a massive 17.62% cushion beneath it β the widest safety margin of all five names. Its SAR continues stepping up ($98.37 β $101.00) as the rally off the $85 lows matures into a genuine trend. The turnaround narrative keeps collecting evidence: SK hynix partnership talks and CEO Lip-Bu Tan's insider buying remain the themes retail keeps citing. When the macro tape gets ugly, the stock that goes down least is telling you where the rotation money wants to live.
Close: $1,071.88 | β2.22% | Flip at $913.49 (β14.78%)
Micron caught the sharpest analyst crossfire of the day β Wells Fargo lowered its price target while Citi raised its own on stronger DRAM pricing expectations, and UBS framed the stock as a "battleground" as investors debate the durability of memory demand. Price told the cleaner story: a 2.22% pullback from $1,096.16 that stayed comfortably inside an uptrend whose SAR support rose from $905.84 to $913.49. That's still a 14.78% buffer. For anyone tracking this name, the lesson of the last two sessions is exactly what SAR discipline preaches: the analysts are arguing about the destination, but the dots above/below price only care about the trend β and the trend is up, day 3 and counting.
| Catalyst | Impact |
|---|---|
| Hot PMI sends 10-year yield above 5% | S&P β0.75%, NASDAQ β1.13% β markets repriced the October Fed meeting hawkishly; the day's dominant force |
| NVDA's six-day win streak snaps | NVDA β1.47% β yield pressure plus Google TPU competition fears (Barron's) and a ~$300.15M director sale (Sep 18) |
| Analyst crossfire hits MU | MU β2.22% β Wells Fargo cut its target, Citi raised its own on DRAM pricing; UBS calls it a "battleground" |

| TrumpβXi summit + tech CEO state dinner | Lisa Su, Jensen Huang, Tim Cook, Elon Musk to attend β AI safety and chip export policy on the table through Friday |
| Anthropic eyes 1 GW data-center lease | Would house Broadcom, Google, and Nvidia chips β structural AI demand signal for AVGO and NVDA |
| Oil rallies on diesel shortage; surprise crude build | Energy pressure returned despite a 3M-barrel stockpile build; Barclays argues oil + rates β not midterms β drive equities this fall |
| Gold breaks below $4,300 | Hawkish Fed bets lift the dollar β the anti-inflation trade is being unwound in real time |
Today was a macro repricing day, and it's worth being precise about the mechanism. The hot services PMI didn't just push the 10-year above 5% β it forced traders to reprice the probability of further tightening at the October meeting, with CPI still running +3.71% YoY (+0.40% MoM per the latest reading of 334.131). In that environment, long-duration equities get sold first, which is why the NASDAQ (β1.13%) lagged the Dow (β0.68%) and why the Russell 2000 (β1.77%) fared worst of all. The VIX at 15.19 (+6.90%) is still low in absolute terms β this was a rebalancing, not a panic.
What's genuinely interesting is how the semiconductor group behaved inside the decline. Four of five names fell between 1.0% and 2.6%, but none of them came within 5% of their bullish SAR levels, and INTC (β1.02%) actually beat the S&P. Compare that to the Aug 24 playbook, when a macro shock flipped MU bearish and pushed the board to 4 Bears / 1 Bull in a single session. The difference is trend maturity: INTC (Day 13) and AMD (Day 12) have SAR levels anchored to months of higher lows, while yesterday's flip (AVGO, Day 2) and Monday's flip (MU, Day 3) are the only fresh, vulnerable structures β and both still held with 5%+ cushions.
Rotation under the surface is the other storyline. Asia was mixed (Nikkei +1.38%, Hang Seng β1.01%), TSX slid 1.61% as Canadian tariff tensions simmered, and the Meta Muse narrative is splitting the AI trade into "agents that disrupt" and "chips that power" β note that Alphabet's 3% Muse-driven loss came on the same day Anthropic's reported 1-gigawatt lease would physically require Broadcom and Nvidia silicon. The market is punishing business-model risk and still paying up for compute capacity. If that distinction holds, our board's four bullish SAR dots are riding the durable side of the AI trade.
The week's binary is Thursday's TrumpβXi dinner. With Lisa Su and Jensen Huang physically at the table, any headline on chip export policy moves this entire board β and the two stocks closest to their SAR lines (NVDA +2.59% from a bullish flip, AVGO β5.23% from a bearish one) will react first and hardest.

The Parabolic SAR (Stop and Reverse) is a trend-following indicator that places dots above or below price. Dots below price = Bullish (uptrend). Dots above price = Bearish (downtrend). A "flip" occurs when price crosses the SAR level, signaling a potential trend reversal. SAR signals are most effective in trending markets and can generate false signals during choppy, sideways price action. This analysis is for educational and informational purposes only.
