Today was the day the AI and memory trades finally split apart. Nvidia delivered a blowout earnings report Wednesday evening β revenue roughly doubled year-over-year and the company guided to ~70% growth next fiscal year β and the stock ripped nearly 9% to touch $230 intraday, pushing the company's market cap back above $5.5 trillion. The bellwether didn't just lead the tape; it flipped its daily Parabolic SAR from Bearish back to Bullish mid-session, the kind of aggressive dot-reversal that confirms momentum investors are all-in on the AI-infrastructure story again.
But the green at the top of the screen masked a genuine divergence underneath. Memory names β Micron above all β fell into Nvidia's celebration, and AVGO rallied hard on the AI theme while Intel caught a jolt on its own infrastructure news. The index that matters most here, the NASDAQ, surged +1.57% to 26,541.35 while a hotter-than-expected PCE print and a quieting VIX told a two-sided story about where risk appetite really stands. Let's dig into the SAR dashboard and what each of the major names is telling us into the close.

Close: $227.98 | +8.74% | Flip at $207.25 (-9.09%)
This is the headline signal of the session. Moving into the open, NVDA was carrying a Bearish SAR that had built throughout last week's earnings-season de-risking. Today the ~8.7% surge β the stock closed at $227.98 off an open near $222.86, printing a high of $230.47 β carved straight through that resistance. The SAR immediately rolled lower to $207.25 as bullish support, marking a clean BearishβBullish flip (Day 1). The flip distance of -9.09% is now your buffer: the stock has room to breathe before a bearish retest. With ~70% forward growth guided and Hugging Face acquisition chatter (reportedly ~$13B) swirling, the trend change here is backed by freshest fundamental fuel on the board β well worth tracking into Jackson Hole.
Close: $476.67 | -0.89% | Flip at $451.34 (-5.31%)
AMD quietly extended its bullish streak to a 10th day on the SAR, but that -0.89% drift on NVDA's best day in the sector is telling: money rotated toward the winner (NVDA) more than the runner-up today. Cathie Wood's ARK trimmed ~$18M of AMD β pairing that with fresh ~$20M AVGO β and the fact AMD didn't catch the same wave suggests the second-place premium is still being questioned. SAR at $451.34 gives it a -5.31% buffer to defend. If NVDA-at-$5.2T keeps squeezing AI money toward one stock, AMD's long-running bullish stand is the one to watch most closely.
Close: $935.39 | -0.32% | Flip at $1,027.40 (+10.01%)
The most instructive non-mover of the day. MU fell while NVDA soared β because while NVDA is pure-units-play, memory is the price component that the market now worries is a tariff target. The Trump administration is reportedly weighing broad semiconductor tariffs (Politico), and that has memory names (MU -2%, SNDK -1.7%, WDC down) sliding even as NVDA's earnings validated AI demand. There's a genuine silver lining: Nvidia itself flagged memory as a key constraint to AI growth β which is structurally bullish for Micron's pricing power long-term, and rebounded into the close after that. But the SAR is unambiguous Bearish Day 4 at $1,027.40; the stock needs a +10.01% grind up to flip. Watch for the tariff overhang + the Sept 30 earnings keep this a murky one.
Close: $92.04 | +4.36% | Flip at $99.18 (+7.70%)
Intel rose +4.36% on Thursday even as it holds Bearish Day 8. The trigger was the expanding Advantech AI-infrastructure partnership (Intel powering its racks) β a reminder that "foundry + physical AI" is the story Intel is selling into its $20B capital raise. But don't mistake it for a SAR shift: price at $99.18 flip level still sits +7.70% away, and the bearish dot is still firmly overhead. A strong close is a start, but trend-followers need the flip, not the headline.
Close: $371.54 | +4.49% | Flip at $402.72 (+8.39%)
AVGO had a strong day β +4.49% to $371.54 β as chips broadly caught a bid and OpenAI built its JalapeΓ±o accelerator with Broadcom in the mix. Cathie Wood's ARK bought 57k shares ($20.5M) ahead of AVGO's next earnings, which is a live hand. But the SAR is still Bearish Day 10 and the price remains a full +8.39% below its $402.72 flip target β the pattern that's held for ten sessions just isn't broken yet. Watch this stock as much as NVDA now: it's a popular tool for riding the AI wave back.
| Catalyst | Impact |
|---|---|
| NVDA blowout: revenue doubled, |
NVDA +8.74%, bullish SAR flip, market cap back >$5.2T |
| NVDA flags memory as a key AI constraint | Long-term bullish for MU pricing power |
| Trump admin weighing broad semiconductor tariffs (Politico) | MU -0.32%, SNDK -1.7%, WDC under pressure |
| ARK rotation: +$20.5M AVGO / -$18M AMD | Differentiated semis: AVGO up, AMD drifting |
| July PCE +3.7% YoY beating forecast | Higher-for-longer inflation; yields re-price |
| INTC-Advantech AI infrastructure partnership | INTC +4.36% |
| Jackson Hole Fed risk / VIX at 14.50 | Overall risk-on but earnings-dependence |
The tape told two stories simultaneously. On the surface it was a banner risk-on session: NASDAQ +1.57%, VIX down nearly 5% to 14.50, NVDA pushing the S&P up +0.72%. The AI infrastructure trade, led by the clear energy/semis leaders, is regrouping after a brutal August memory correction. But the divergence is the actionable signal β NVDA essentially owns the AI momentum trade, and memory (MU, SNDK, WDC) sold off even into bullish, price-validating guidance on the tariff fear. That's an intra-sector rotation, not a uniform rally.
The macro pill acts as ballast: July PCE came in at +3.7% YoY, above the ~3.6% consensus, extending the elevated run. With Fed chief Kevin Warsh noted to be watching a "roaring" tech trade carefully, there's a Jackson Hole / policy-reaction risk underneath all this chip strength. The VIX is grinding lower, but long yields baking in re-rating pressure means the forward-looking gold-silver trade, the Treasury component and the macro print all still matter for this sector.
As the board settles at 2 bulls / 3 bears, the clearest read is a pause-for-concentration: NVDA proved the AI-capital base is firm, memory is where the market is waiting on hardware/tariff clarity, and the value + retail + infrastructure player names (INTC, AVGO) hold bearish patterns despite solid bounces. The next bell β an ecosystem of earnings, a hot PCE, a Jackson Hole β will decide whether the NVDA flip is the start of a sustained re-listening, or an overshoot.

The Parabolic SAR (Stop and Reverse) is a trend-following indicator that places dots above or below price. Dots below price = Bullish trend. 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.
