SanDisk Surged 11.90% and Micron 6.10% on One Analyst Note. A Stronger Jobs Report Barely Moved the Index

One bullish note on memory-chip supply moved more capital Friday than a jobs report that beat consensus by a factor of three.

The S&P 500 (SPY) closed Friday at $770.19, down a modest 0.39%, even after the Bureau of Labor Statistics reported 162,000 August payroll additions against a consensus estimate of roughly 53,000 — a beat large enough to push September Fed rate-hike odds to 60% and spike short-term Treasury yields, per same-day Motley Fool coverage. The index barely noticed. Underneath it, SanDisk rose 11.90% to $1,740.00 and Micron rose 6.10% to $1,016.59 after Lynx Equity Strategies issued bullish notes rating both stocks a clear buy — 49% anticipated upside on SanDisk, 33% on Micron — citing AI-driven memory demand as chipmakers ramp production, per the same day's Motley Fool coverage. ASML, which supplies the lithography systems those chipmakers depend on, gained in sympathy. Meanwhile Netflix fell 5.35%, Palantir 4.49%, Coinbase 4.18%, and Apple 2.51% on real, dated news of its own: production issues with its foldable iPhone and a canceled foldable MacBook, compounded by the same memory-chip scarcity that lifted Micron, per Motley Fool. Friday looked calm from the index level and violent underneath it.

Story one: a 49%-upside call on SanDisk, a 33%-upside call on Micron

Lynx Equity Strategies rated both SanDisk and Micron a clear buy in a note covered the same day by The Motley Fool, citing 49% anticipated upside for SanDisk and 33% for Micron, on the view that both chipmakers are ramping production to meet AI-driven computing demand. SanDisk closed at $1,740.00, up 11.90% on the day; Micron closed at $1,016.59, up 6.10%. The note wasn't the only tailwind: a separate same-day Motley Fool piece tied part of SanDisk's move to Nvidia's $12.9 billion acquisition of Hugging Face and to Dell's own commentary about memory-supply constraints in AI servers, while a same-day Zacks Investment Research piece gave SanDisk a Zacks Rank #1 (Strong Buy), citing datacenter revenue that "doubled sequentially and surged 437% year-over-year" on favorable NAND pricing. For Micron, a separate same-day Motley Fool market wrap reported the stock rose specifically on news that the company plans to double AI-oriented high-bandwidth-memory production by 2027. ASML, which supplies the lithography tools chipmakers need to expand that capacity, rose 4.17% in sympathy, framed in the same coverage as a "pick-and-shovel" beneficiary of the buildout.

Story two: the jobs report that beat big and moved little

The Bureau of Labor Statistics reported 162,000 August payroll additions, roughly three times the approximately 53,000 consensus estimate, according to same-day Motley Fool coverage. That beat pushed September Fed rate-hike odds to 60% and sent short-term Treasury yields higher, the kind of data point that has moved markets sharply on other days this year. Friday it didn't: the S&P 500 fell just 0.39% to $770.19, the Nasdaq-100 (QQQ) actually rose 0.18% to $718.96, and the same Motley Fool piece explicitly argued the jobs report "wasn't really why" the major indices dipped, pointing instead to Apple's foldable-device production issues and a 6.16% decline in Tesla (not covered on this site) following disappointing early Cybercab reviews. Elsewhere, Lululemon fell roughly 18% on a revenue miss and cut guidance, and Fair Isaac fell nearly 16% after public pricing criticism from the Federal Housing Finance Agency — both per the same day's Motley Fool "Stock Market Midday" coverage, and both outside this site's coverage list.

Story three: the mechanism connecting Apple's decline to Micron's rally

Apple's 2.51% decline is the clearest thread tying Friday's two storylines together. The same Motley Fool coverage that reported Apple's foldable-device production issues specifically named "expensive and scarce memory chip availability" as a compounding factor — the identical memory shortage that Lynx Equity Strategies cited as the bull case for Micron and SanDisk. One company's input-cost problem is, mechanically, the reason two other companies' stocks rallied 6-12% the same day. That is not a coincidence of two unrelated headlines landing together; it is the same scarce-supply-and-pricing-power dynamic read from opposite sides of the AI-hardware supply chain.

What the analyst note's own numbers imply for SanDisk

Lynx Equity Strategies' 49% anticipated-upside figure for SanDisk is a single analyst's dated call, not a consensus and not this site's forecast. Held out as one endpoint of a range rather than a guaranteed outcome, the table below sizes what that call and its opposite — giving back Friday's entire rally — would look like in price terms.

ScenarioImplied pricevs. Sept 4 close
$1,740.00 (today's close, unchanged)$1,740.00
+25% (partial move toward the analyst target)$2,175.00+25.0%
+49% (Lynx Equity Strategies' full anticipated upside)$2,592.60+49.0%
Reversal to Wednesday's $1,554.99 close (giving back all of today's rally)$1,554.99−10.63%

Assumptions, stated plainly. This table applies Lynx Equity Strategies' reported 49% anticipated-upside target for SanDisk, disclosed via Motley Fool coverage on September 4, 2026, as one endpoint of a range, alongside a partial-move and a full-reversal scenario. It is one analyst's dated call, not a consensus figure and not this site's own forecast, and it says nothing about timing — reaching $2,592.60 eventually is not the same claim as reaching it soon. NAND pricing power, the mechanism behind Friday's rally, is itself cyclical: memory-chip shortages have reversed before, sometimes as quickly as they built. The downside scenario shown is not a prediction either; it simply sizes what giving back one day's gain would mean in dollar terms.

Elsewhere on the tape

AMD rose 4.69% to $477.57 and Intel rose 4.51% to $95.80 with no dated company-specific headlines of their own beyond the same broad AI-infrastructure and memory-chip coverage lifting the rest of the sector. Vertiv rose 4.35% and Talen Energy rose 3.76%, both power/data-center-infrastructure names, again with no fresh dated news found. Estée Lauder rose 2.97% to $103.86 with no dated headline found in the sources checked. Microsoft fell 2.04% and Salesforce fell 1.97%, both with no company-specific news found; both moved with the broader softness this site's Opinion piece examines in more detail.
