Daily Brief Archive: August 7, 2026 — U.S. & Hong Kong Stock Analysis

Technicals — It closed at $881.47, down just 1.31% on a day the memory chain was gutted — WDC fell 13.03% and SNDK 6.81% — and that relative strength is the most notable data point today. Price remains 9.3% below the 50-day ($971.96) and far above the 200-day ($531.67). RSI(14) at 47.9 and RSI(7) at 50.1 are both neutral. The 11.1% weekly gain is intact and the monthly decline narrowed from -14.3% to -4.5%. ATR of $84.95 implies a 9.6% daily range. The intraday span of $827.00–$905.80 was violent but the close landed in the upper half. The $800 level remains the structural line beneath my stop reference.

Fundamentals — Trailing revenue of roughly $41.46B grew 167% with EPS up 697% on a 72.6% gross margin — elite for a memory supplier — at 20.0x earnings. The key distinction from SanDisk is business mix: Micron's profit engine is DRAM and HBM, whereas today's panic concerns NAND spot pricing. Bank of America's framing is worth recording: its base case already assumes Micron's DRAM prices fall 10% and NAND 18% in calendar 2028, and even under a severe bear case it believes Micron sustains strong profitability relative to prior cycles.

News — Micron swung through a wide $827.00–$905.80 range on 8/6 before closing down 1.31%. The whole semiconductor and memory complex was under pressure: Western Digital collapsed 13.03% on a sudden drop in NAND spot pricing and elevated inventory ahead of its planned separation, while SanDisk fell 6.81% despite a large beat. The central debate has shifted from whether AI demand is real to whether hyperscalers will earn attractive returns on their enormous AI investments, and after a huge first half for memory stocks many investors are locking in gains. Bank of America reiterated its bullish stance, arguing Micron's profitability far exceeds prior cycles even under a severe pricing decline.

Technicals — It closed at $218.99, down 0.10%, essentially unmoved on a day the memory chain was gutted and semis broadly struggled — among the strongest relative showings today. Price sits well above the 50-day ($205.85) and 200-day ($193.77) in a complete bullish stack. RSI(14) at 61.4 is healthily firm with RSI(7) at 71.2 warm but manageable. Weekly and monthly gains of 13.2% and 13.8% leave it just 7.4% below the $236.54 high. ATR of $7.79 implies a 3.6% daily range, among the mildest of today's deep dives — a number that by itself explains the difference in holding experience.

Fundamentals — Trailing revenue grew 70.7% and EPS 110.3% on a 74.1% gross margin at 33.5x earnings — an unusually good growth-to-valuation match at a $5.3T market capitalization. Sixty-four analysts carry a 1.12 rating near strong buy with an average target of $314.29 implying 43.5% upside, the most unified bullish consensus among megacap tech. The market's emerging doubt about hyperscaler returns on AI capex is in theory Nvidia's largest long-term risk, yet in the near term it remains the direct recipient of that spending.

News — Nvidia finished essentially flat on 8/6, down 0.10%, showing marked resilience amid a broad tech and semiconductor selloff. Two pressures drove the sector: the NAND pricing panic triggered by Western Digital that dragged the memory chain, and a newly concentrated doubt over whether hyperscalers can earn attractive returns on their enormous AI investments — the first systematic challenge to the entire AI capex narrative. Headlines around Samsung and China's DeepSeek added further noise. Against that backdrop, Nvidia's flat close shows the market still prices it apart from the memory makers.

Technicals — It closed at $155.92, down 1.58%, a modest give-back on a day three heavyweight software names cratered together — DDOG -19.0%, HUBS -19.1%, APP -19.7% — making its relative strength conspicuous. Price holds above the 50-day ($131.81) and 200-day ($152.33), preserving the bullish stack built on the 8/4 gap. RSI(14) at 66.4 is firm without being overbought and RSI(7) at 72.7 is moderate. Weekly and monthly gains stand at 28.7% and 16.6%, with an ATR of $8.38 implying a 5.4% daily range. The $207.52 high is 33.1% above, while the 200-day at $152.33 is the key post-gap support and today's close held above it.

Fundamentals — Q2 revenue of $1.94B grew 93%, with US commercial up 149% and government up 90% at a 55.1% net margin, and full-year guidance was raised to $8.15–8.16B. At 133.3x trailing earnings it remains among the most expensive names here, but today's control group is instructive: DDOG trades at 611.9x with 29.5% growth and HUBS at 71.7x with 21.1% growth, and both were savaged for guidance that fell short. Against that comparison, Palantir's 78.9% revenue growth and 84.8% gross margin explain why it gave back only 1.58%.

News — Palantir slipped 1.58% on 8/6, a normal digestion after the 29.45% surge on 8/4. What deserves recording is the sector backdrop: Datadog fell 19.0% — its largest single-day drop on record — despite beating and raising full-year guidance; HubSpot fell 19.1%, also a record single-day decline, on soft guidance and net customer additions far below its internal target; and AppLovin fell 19.7% on a revenue miss and slowing core gaming. The common thread is decelerating growth, and Palantir's US commercial revenue grew 149% last quarter. That gap is why it wasn't swept up today.

Technicals — It closed at $114.92, up 6.14%, on relative volume of 2.93x — a high-volume advance on lockup day, the opposite of what the market broadly expected. The name still lacks 50-day and 200-day references, leaving the $104.83–$225.64 52-week range as the only anchor, with price 9.6% above the low and 49.1% below the high. RSI(14) at 42.5 and RSI(7) at 46.2 are both neutral. The week is down just 0.2% while the month is down 27.7%. ATR of $11.10 implies a 9.7% daily range. Technical analysis here remains constrained by the absence of moving-average structure.

Fundamentals — Q2 revenue of $7.81B grew 92% and beat estimates, but quarterly capital expenditure of roughly $18.4B ran at 2.4x revenue. The company is now a three-segment enterprise spanning space, connectivity and AI following the February 2026 integration of xAI and X, at a market capitalization near $1.51T. There is still no P/E or gross margin available for cross-checking, making it the least financially transparent name in today's deep dives. The $227.09 consensus target implies 97.6% upside, the highest on the board — but that figure rests on an extremely thin base of verifiable financials.

News — August 6 was SpaceX's first major post-listing lockup expiration — the foreseeable supply shock I named explicitly in the two prior briefs. The outcome inverted the expectation: the stock rose 6.14% on relative volume of 2.93x. The maiden report after the close on 8/4 had knocked it as much as 8.8% postmarket on $18.4B of quarterly capex, but that damage was largely repaired within two sessions. Two things follow: the market had priced lockup selling fully, arguably excessively, in advance; and the 92% revenue growth narrative still finds buyers. The question of payback on that capex isn't resolved — merely deferred.
