Market Snapshot โ July 21, 2026 (4:15 PM ET)
| Index | Level | Change |
|---|---|---|
| S&P 500 | 7,509.20 | +0.89% |
| NASDAQ | 25,837.21 | +1.29% |
| Dow Jones | 52,224.64 | +0.74% |
| VIX | 16.98 | -8.96% |
Semiconductors stole the show on Tuesday, leading a broad market rally that sent the VIX tumbling nearly 9% back below 17. The relief was palpable across the chip space: all five of our tracked stocks posted solid gains, with MU surging more than 12% and both AMD and INTC adding over 8%. The bounce was powered by a mix of bullish analyst calls, positive AI hardware newsflow, and a classic buy-the-dip rotation after last week's brutal sell-off.
The Russell 2000 outperformed the major indices with a 1.53% gain, signaling that the rally wasn't confined to megacap tech โ broader market participation was evident. The NASDAQ led the majors at +1.29%, reclaiming the 25,800 level convincingly. But the real story is what happened at the stock level, and the SAR dashboard tells the tale.

NVDA extended its bullish SAR streak to Day 10, with SAR inching up from $197.80 to $197.97. The stock climbed nearly 2% on a wave of positive catalysts: the company confirmed its next-generation Rubin AI chips are now shipping to customers and entering full production. NVDA also disclosed a 9.3% passive stake in neocloud provider Nebius (NBIS), sending that stock soaring โ a strategic move that reinforces NVDA's ecosystem grip. Meanwhile, CNBC detailed NVDA's Vera CPU ambitions, setting up a direct challenge to AMD and Intel in the data center CPU market. With 4.50% of cushion above SAR, the bulls are comfortable โ but earnings season next week from Mag 7 customers will be the real test.
Close: $970.82 | +12.17% | Flip at $1,063.49 (+9.55%)
The star of the day. MU exploded 12% higher after Bank of America argued that cheap, open-source Chinese AI models โ rather than threatening chip demand โ could actually boost memory consumption as enterprise AI workloads multiply. Stephanie Link, CIO at Hightower, publicly bought MU on CNBC's "Halftime Report," adding institutional credibility to the dip-buying thesis. MU's SAR dropped sharply from ~$1,092 to $1,063.49 in a single day โ the fastest SAR compression among our five stocks. At this pace, if MU can string together a few more sessions like today, a bullish SAR flip could arrive much sooner than the 9.55% gap suggests. The stock traded as high as $982.88 intraday before settling at $970.82.
Close: $544.43 | +8.11% | Flip at $558.57 (+2.60%)
AMD is the stock to watch tomorrow. The 8% surge โ fueled by continued enthusiasm around the Microsoft Helios AI rack deal โ brings AMD within a razor-thin 2.60% of a bullish SAR flip. Tomorrow is AMD's "Advancing AI 2026" event in San Francisco, where analysts expect details on next-gen Instinct GPUs and potentially a new major customer announcement (Anthropic is the rumor). If AMD can rally just $14 from current levels, it will trigger a bullish SAR flip for the first time since July 2. Jefferies has a $615 target, and KeyBanc's John Vinh reiterated his bullish stance. The setup couldn't be more dramatic.
Close: $105.45 | +8.64% | Flip at $113.86 (+7.97%)
INTC joined the relief rally with an impressive 8.64% gain, reclaiming the $105 level from a $97 low just yesterday. The SAR resistance continues its descent โ now at $113.86, down from ~$118 โ reflecting the bearish trend's gradual erosion. However, with a 7.97% gap to flip, INTC still has considerable work to do. The stock remains the most deeply entrenched bearish signal in our group alongside MU. Barron's highlighted that TSMC is set to "ratchet AI costs even higher," a dynamic that could benefit Intel's foundry ambitions longer-term but adds near-term uncertainty.
Close: $386.50 | +2.21% | Flip at $405.55 (+4.93%)
AVGO posted a respectable 2.21% gain but underperformed the broader chip rally. At only Day 3 of its bearish SAR signal, AVGO's trend is still fresh. Morgan Stanley reiterated its overweight rating, calling AVGO "a core AI winner," while UBS suggested the semiconductor momentum unwind "could be approaching its final stages." The $405.55 SAR level is within reach โ a 4.93% move โ and with the Apple-Broadcom $30B chip deal as an ongoing tailwind, a bullish flip within the next week is a realistic scenario if the rebound sustains.

| GM beats & raises on strong Q2 earnings | Broad market sentiment boost; industrial demand signals confidence |
| 3M soars on strong earnings report | DJIA leader adds to positive macro tone |
| UBS: Semi momentum unwind "approaching final stages" | AVGO +2.21%, encouraging signal for battered chip holders |
Today's rally wasn't just about individual stock catalysts โ it reflected a broader shift in market psychology. After two weeks of relentless selling that saw the SOX semiconductor index drop sharply from its highs, buyers finally showed conviction. The VIX collapsing below 17 (-8.96%) tells you everything: fear is receding, at least for now.
The macro backdrop remains complex. President Trump's 50% tariff threat on Canadian goods injected fresh trade-war uncertainty, and the US-Iran conflict continues to roil energy markets with oil prices testing new highs. Yet equities shrugged it off โ a testament to the resilience of the AI investment thesis. Earnings season is providing a constructive backdrop: GM's beat-and-raise quarter and 3M's strong results set a positive tone ahead of this week's main events.
Speaking of which: Tesla reports Wednesday (July 22), and Alphabet reports the same day. Both are critical reads on AI spending trajectories. The options market is pricing a sharp move in TSLA, and GOOGL's cloud and AI commentary will directly impact the semiconductor demand narrative. This week is make-or-break for the relief rally.
One more notable data point: the Russell 2000's 1.53% gain outpaced the NASDAQ's 1.29%, suggesting the rally is broadening beyond the usual megacap suspects. This rotation into small caps โ if sustained โ would be a healthy sign that market participants see the economic expansion continuing despite geopolitical headwinds.
AMD is on the verge of a bullish SAR flip โ just 2.60% away โ Tomorrow's "Advancing AI 2026" event could be the catalyst. A close above $558.57 flips AMD bullish. Watch closely.
MU's 12% surge is the most dramatic SAR gap compression we've seen โ SAR resistance dropped $29 in one day. If the rally continues, the bullish flip target of $1,063.49 could come into view within a week, not weeks.
NVDA is the lone bullish signal โ and it's strengthening โ Day 10 bullish, Rubin chips shipping, Vera CPU ambitions expanding the TAM. NVDA is quietly rebuilding momentum while others play catch-up.
The VIX at 16.98 signals fear is fading โ but earnings season is the real test โ Tesla and Alphabet report this week. Their AI capex commentary will either validate or challenge the chip rebound thesis.
All bearish SAR levels moved lower today โ Even the stocks still in bearish trends (MU, AMD, INTC, AVGO) saw their SAR resistance compress. This is the ideal setup for potential bullish flips: prices rising while SAR resistance falls.

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.
