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.

Long Lean bullish

Maintaining the long. Today was this position's first stress test and it passed: with the chain gutted — WDC -13.03%, SNDK -6.81% — Micron gave back only 1.31% and kept an 11.1% week intact. Business mix is the reason: today's panic originated in NAND spot pricing while Micron's profit engine is DRAM and HBM. The stop stays at $798 below the $800 level, a break of which invalidates the whole reversal; the entry zone shifts slightly from $855–885 to $845–880 and the target holds at $1,000. BofA's base case already embeds 2028 price declines, which buys this position time.

A 20.0x multiple against a 72.6% gross margin and 167% revenue growth, with structural HBM and DRAM demand driven directly by AI compute. BofA's bear-case math shows that even if a pricing downcycle arrives, the earnings base sits far above prior cycle troughs.

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.

Maintaining the long and the bullish stance. Today's entire signal is relative strength: the memory chain was gutted, semis broadly struggled, the AI capex narrative faced its first systematic challenge — and it fell 0.10%. Entry at $208–216 above the 50-day at $205.85, stop at $198 structurally above the 200-day at $193.77, and a $250 target just beyond the $236.54 high. With a 3.6% ATR, that 9.6% stop distance absorbs more than two standard deviations of daily movement, so this can be sized as a normal allocation rather than a wager — a scarce property among today's names.

A 74.1% gross margin and 70.7% revenue growth still hold at a $5.3T valuation, and 33.5x is not expensive for that pair. Sixty-four analysts converging on 43.5% upside reflects fundamental consensus rather than a crowded trade.

Score8/10RSI(14) 62.51-week gain +10.6%P/E TTM 70.0AI semi growth +143%Consensus upside +25.9%

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.

Maintaining the long and the bullish stance. Today validated yesterday's read: the reclaim of the 50-day at $394.92 held, and it finished green on a day the sector struggled. Entry at $400–414 above the 50-day, stop at $383 structurally between the 50-day and the 200-day at $367.20, and a $470 target short of the $495 high. There is a second layer to the logic: today's doubt about returns on AI capex sharpens hyperscalers' incentive to cut costs with custom ASICs — the same doubt that is a risk for Nvidia is an order book for Broadcom.

Custom ASIC is the only realistic path for hyperscalers to reduce general-purpose GPU dependence and demonstrate efficiency on AI spending. AI semiconductor growth of 143% and a 200%-plus Q3 guide show that substitution accelerating.

Score8/10RSI(14) 66.41-week gain +28.7%P/E TTM 133.3Signal return +23.88%Consensus upside +26.8%

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.

Long Lean bullish

Maintaining the long. Today was a quality check on this position: in the same expensive-software cohort, DDOG, HUBS and APP each fell roughly a fifth while Palantir gave back 1.58% and held the 200-day at $152.33. The difference is verifiable growth — 149% US commercial expansion is not a narrative. Entry at $148–155 near the 200-day, stop at $137 below the gap's midpoint, and a $196 target all carry over from 8/4, because neither the logic nor the key levels have changed. The 133.3x multiple remains the single largest risk, which is why this stays lean bullish rather than bullish.

Twin engines at 149% US commercial and 90% government growth prove enterprise AI spending has entered scaled integration, and a 55.1% net margin shows it isn't growth bought with cash burn. But 133.3x prices years of flawless execution in advance.

  • At 133.3x a single deceleration is unforgiven, and today's DDOG is the live case study
  • Heavy government exposure ties revenue to budget and political cycles
  • The entire software sector's valuation is being systematically reassessed
