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

Technicals — It closed at $1,258.58, down 6.81%, yet the week is still up 10.9% — the earlier run absorbed part of the earnings expectation, making this a sell-the-news reaction rather than a collapse. Price holds above the 20-day but sits 25.8% below the 50-day ($1,695.65) and far above the 200-day ($866.93). RSI(14) at 43.1 and RSI(7) at 43.0 are both neutral-to-soft with no overbought pressure. ATR of $188.27 implies a 15.0% daily range, still the most extreme on the board. The stock is 46.5% below its June high of $2,354.39 and down 22.3% on the month.

Fundamentals — FY26 Q4 revenue reached $8.965B, up 51% sequentially and 372% year over year, with GAAP net income of $6.90B and diluted EPS of $43.97, non-GAAP EPS of $39.25 and an 84.6% gross margin — all above the top end of guidance. Full-year revenue of $20.25B grew 175%. Roughly one third of the sequential gain came from volume and two thirds from pricing. Q1 FY27 guidance calls for revenue of $10.3–10.8B, a non-GAAP gross margin of 83–85% and EPS of $44–46, alongside a new $14B buyback authorization. The pivotal change: the trailing multiple fell from 49.6x pre-print to 17.3x — driven not by the share price but by an explosion in the earnings denominator.

News — SanDisk released FY26 Q4 results after the close on 8/5, beating the high end of guidance on every metric. Yet the stock fell 6.81% on 8/6 — not because of the print but because of what Western Digital said the same day: NAND spot pricing has turned down sharply, raising concerns about memory makers' gross margins. WDC plunged 13.03% and dragged the whole chain with it. The market's logic is plain: two thirds of SanDisk's 84.6% margin came from pricing, so if NAND has peaked, that margin is a cycle-top reading rather than a run rate. Management's Q1 FY27 guidance of an 83–85% gross margin explicitly disputes that reading.

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 $420.56, up 0.55%, finishing green on a day semiconductors were broadly pressured — excellent relative strength. Price holds firmly above the 50-day ($394.92) and 200-day ($367.20) in a complete bullish stack. RSI(14) at 62.5 is healthy and RSI(7) at 75.0 runs warm. Weekly and monthly gains of 10.6% and 14.7% leave 17.7% of headroom to the $495.00 high. ATR of $17.09 implies a 4.1% daily range, mild for semis. The 50-day at $394.92 is the nearest structural support, reclaimed and confirmed just yesterday.

Fundamentals — Q2 FY26 AI semiconductor revenue of $10.8B grew 143%, with Q3 AI revenue guided to $16B at over 200% growth. Trailing revenue growth is 32.3% with EPS up 125.8% on a 65.7% gross margin at 70.0x earnings. Today's doubt about hyperscaler returns on AI capex is arguably a tailwind for Broadcom: the more cloud providers need to prove spending efficiency, the greater their incentive to substitute custom ASICs for general-purpose GPUs — and that substitution is exactly where Broadcom's revenue comes from.

News — Broadcom rose 0.55% on 8/6, standing out against a gutted memory chain and broadly pressured semiconductors. The core driver remains expanding custom ASIC partnerships with major cloud service providers, as tech giants seek tailored silicon for proprietary AI workloads and Broadcom's leadership keeps winning high-value contracts. Morgan Stanley had reiterated Overweight across both Broadcom and Nvidia. Notably, the day's doubts about returns on AI capex did not touch Broadcom, suggesting the market files custom silicon under cost reduction rather than spending.

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 HK$178.00, down 0.95%, falling less than the broad market on a day the Hang Seng dropped 1.49% and HS Tech 2.28% — solid relative strength. Price holds above the 50-day (HK$146.36) and 200-day (HK$122.24) in a complete bullish stack. RSI(14) eased from 76.3 to 68.9 and RSI(7) from 86.7 to 71.2, materially relieving overbought pressure — exactly the healthy digestion anticipated when yesterday's note warned that any good news landing could trigger profit-taking. The week is still up 13.3% and price sits just 5.2% below the HK$187.80 high. ATR is HK$7.92.

Fundamentals — First-half 2026 revenue of RMB28.90B grew 38.93% with net profit of RMB11.08B up 29.43%, crossing RMB10B for a half year for the first time, while full-year revenue guidance rose from RMB51.3–53.0B to RMB58.5–60.5B. The stock trades at 21.5x trailing earnings with EPS up 65.7%, revenue up 29.9% and a 52.6% gross margin. Consensus targets have climbed from HK$188.77 on 8/4 to HK$208.74 on 8/5 and now HK$213.85 — two raises in three days, showing analysts still catching up to the guidance revision. Huachuang Securities has noted that warming pharma investment and financing globally should transmit CRO front-end order growth into earnings.

News — Hong Kong weakened across the board on 8/6: the Hang Seng fell 1.49% to 25,530.28 and HS Tech 2.28%, with platforms broadly lower — Baidu -4%, Alibaba -2.89%, Tencent -2.64%, Xiaomi -2.82% — while southbound flows turned to net selling of HK$1.46B, the first flip from buying in recent sessions. Against that, WuXi AppTec fell only 0.95%. The prior session on 8/5 had seen its H-shares gain more than 11% and its A-shares hit limit-up at a five-year high, adding over RMB38B of market value in a day. TCM and innovative-drug names were among the few directions attracting money that day.

Technicals — It closed at HK$125.40, up 0.80% on this cross-timezone snapshot basis, while the local Hong Kong session on 8/6 fell 2.89%. Price holds above the 50-day (HK$111.45) but remains 8.8% below the 200-day (HK$137.56) — still the key unreclaimed gate, and a wider gap than the 7.5% of the prior two sessions. RSI(14) eased from 68.9 to 63.8 and RSI(7) from 79.6 to 67.8, relieving overbought pressure. The week is up 9.9% and the month 29.3%, a 41.5% recovery from the HK$88.65 low. ATR is HK$4.88.

Fundamentals — It trades at 20.8x trailing earnings with EPS down 16.7%, revenue growth of just 4.6% and a 39.3% gross margin — the reported fundamentals remain unremarkable, and this rally is priced off an AI asset rerating rather than the current income statement. The Qwen3.8 model released on 8/3 carries 2.4 trillion parameters and ranks second only to Anthropic's Claude series on the third-party Arena leaderboard. The HK$184.97 consensus target implies 47.5% upside, the highest among today's Hong Kong names and wider than yesterday's 45.0% as the price pulled back.

News — Hong Kong platform stocks weakened across the board on 8/6, with Alibaba down 2.89% in the local session alongside Baidu off more than 4%, Tencent -2.64%, JD -2.08% and Xiaomi -2.82%, as the HS Tech index fell 2.28% to 4,820.78. The notable shift was in flows: southbound turned to net selling of HK$1.46B, a sharp reversal from 8/4 when Alibaba led turnover on both the Shanghai and Shenzhen channels. The names that firmed were pure AI model plays — MiniMax up more than 17% and Zhipu up 4% — so money didn't leave the AI theme, it rotated from large platforms into model-native names.

Technicals — It closed flat at HK$479.20 on this cross-timezone snapshot basis, while the local Hong Kong session on 8/6 fell 2.64%. Price holds above the 50-day (HK$454.16) but sits 11.7% below the 200-day (HK$535.36), a gap that widened noticeably from 8.9% two sessions ago. RSI(14) eased from 60.7 to 55.8 and RSI(7) from 68.5 to 56.3, returning to neutral — amid today's field of extreme overbought and deeply oversold readings, Tencent's position remains among the least worrying. The week is up 2.0% and the month 3.9%, with an ATR of HK$15.48 and the 50-day at HK$454.16 as the nearest structural support.

Fundamentals — It trades at 17.2x trailing earnings with EPS up 21.3%, revenue up 15.0% and a 54.8% gross margin, putting the PEG well below 1 — the best growth-to-valuation match in today's field. Fifty-three analysts average a HK$690.65 target implying 44.1% upside at a 1.14 rating, an unusually tight consensus, with the gap wider than yesterday's 41.2% after the price eased. Tencent's central tension is unchanged: the fundamentals are beyond reproach but there is no catalyst to force a rerating — and today's rotation into pure model names like MiniMax and Zhipu bypassed it once again.

News — Tencent fell 2.64% in the local Hong Kong session on 8/6, tracking the HS Tech index down 2.28% alongside the broader platform complex. Baidu fell more than 4%, Alibaba 2.89%, JD 2.08% and Xiaomi 2.82%, while southbound flows turned to net selling of HK$1.46B. The names that rose were AI model plays — MiniMax up more than 17% and Zhipu up 4% — plus defensive corners such as coal and traditional Chinese medicine. Tencent had no standalone negative and simply traded as sector beta, but for a second consecutive session money chose to route around it toward pure model names, confirming it still isn't in the front rank of AI-theme allocation.
