Retrieved posts serve solely as a factual data source and do not represent the views of this platform or the author. Versus the prior day (which centered on pre-market Mag7 gains and Micron's Hiroshima expansion + Ford deal), this edition shifts the main thread to: Tuesday's tech-led US selloff — Nasdaq -1.16% as storage/chips gave back gains (Micron -4.7%, Tesla -4.0%, while Nvidia bucked the tape at +0.7%); a debate over "shifting AI leadership" sparked by Samsung's +1810% Q2 operating-profit surge; NY Fed 1-year inflation expectations rising to 3.67%, highest since Sep 2023; DeepSeek developing its own AI chip; and Hang Seng closing -0.51%. Only genuinely retrieved results are shown; nothing is padded.

1. Key Events

• Tech-led US selloff, Nasdaq -1.16% to 25,818.69 as chips gave back gains: @KobeissiLetter flagged intraday "Nasdaq 100 extends losses to over -1% as chip stocks pull back"; S&P 500 closed 7,503.85 (-0.45%), Dow 52,925.15 (-0.25%) — tech weights clearly lagged. 𝕏

• NY Fed 1-year inflation expectations rise to 3.67%, highest since Sep 2023: @unusual_whales, @zerohedge and @LizAnnSonders reported the 1-year up from 3.46% to 3.67% and 3-year from 3.13% to 3.34% (highest since 2022) — rising inflation expectations weigh on risk appetite. 𝕏¹ 𝕏²

• Hang Seng closes -0.51% at 23,496.89: @aideninvestment and @BBNTimes_en reported the index down 119.43 pts from Monday's 23,616.32 — HK extends its soft consolidation. 𝕏

• S&P 500 CAPE tops 40x, highest since the 2000 Dot-Com Bubble: @FirstSquawk reported the cyclically adjusted P/E climbing above 40x, an extreme valuation stoking caution. 𝕏

• Samsung Foundry challenges TSMC: order backlog reportedly up to KRW 50T, Meta/Anthropic eye Samsung 2nm: @dnystedt reported Samsung's foundry backlog rising, with Meta seeking Samsung's 2nm for its MTIA AI chips and Anthropic also interested — a wrinkle in the foundry landscape. 𝕏

2. Institutional & Media Coverage

Factual reporting

• Nasdaq leads lower, market drivers (@KobeissiLetter / @CNBC / @3Xtraders): @KobeissiLetter's "Nasdaq 100 down over 1%, chip drag" was the day's lead (250k+ views); @CNBC pre-market "futures little changed as investors weigh Middle East tensions and await Fed minutes"; @3Xtraders noted "NYSE failed to hold 24k, Nasdaq -1.25%, all AI-driven." All factual, pointing to a broad pullback led by tech weights. 𝕏¹ 𝕏²

• Inflation expectations tick up (@unusual_whales / @zerohedge / @LizAnnSonders): NY Fed June 1-year at 3.67% (prior 3.46%), 3-year 3.34% (prior 3.13%), reported by three accounts; @LizAnnSonders added it's the highest since Sep 2023, feeding marginal worry over the Fed's rate path. 𝕏

• Breadth and ISM data (@RyanDetrick / @LizAnnSonders): @RyanDetrick posted twice — "breadth keeps improving, more stocks above their 20/50/200-day MAs" and "NYSE common-stock A/D line at a new high, the bull market is alive and well" (~60k combined views); @LizAnnSonders updated charts showing ISM manufacturing/services employment components rising, services inventories pulling back, and prices-paid falling in June (no written view). 𝕏

• Valuation and geopolitics (@FirstSquawk / @DeItaone): @FirstSquawk reported S&P CAPE above 40x (highest since the dot-com bubble); @DeItaone reported "five NATO members projected to already spend over 3.5% of GDP on core defence this year." 𝕏

• 3-year note auction (@FirstSquawk / @financialjuice): The Fed placed $6.0B in bids at the US 3-year note auction — a factual rates-side flash. 𝕏

Views / ratings

• Samsung may signal an AI leadership shift, yet "everything revolves around Nvidia" (Jim Cramer, via @CNBC): Cramer said the market's reaction to Samsung may signal a leadership shift, while stressing "everything still revolves around Nvidia despite its lagging stock" — a two-sided read on an AI-leader changing of the guard. 𝕏

• Goldman upgrades Nittobo to Buy, cautious on TSMC's glass substrate (@mingchikuo): Ming-Chi Kuo said a key reason for Goldman's Nittobo upgrade was its cautious view on TSMC's glass core substrate (GCS) progress, and that the likelihood of TSMC giving major GCS/CoPoS updates at its July earnings call may be low — a cooling of the advanced-packaging narrative. 𝕏

Note: This round, @Reuters, @WSJ, @FT and @business mostly posted macro/bank-research wraps with little substantive single-name US flash; HK/China coverage from authoritative media (@yicaichina, etc.) was thin, with the real volume concentrated in @cnfinancewatch's A-share/supply-chain pre-market notes.

3. KOL Bull & Bear Views

US broad market / Semis·AI

Bullish / structurally optimistic

• Breadth improving, bull market alive (@RyanDetrick, ≈270 likes / 27 reposts / 23k views): "A/D line at a new high; as we've said for months, this improving breadth is a good thing and suggests the bull market is alive and well" — the day's weightiest bull case. 𝕏

• US market still strong, S&P follow-through signal (@yo_is_nekura, ≈1 like / 30 views): "US regime 74/100, strong but slightly overheated... S&P 500 has a follow-through day signal, the market is still strong." 𝕏

• Nvidia GPUs still the standard, pricing power over AMD/MTIA (@jukan05, ≈20 likes): "When GPU capacity is re-rented, Nvidia GPUs command far higher prices than MTIA or AMD. Nvidia GPUs are still the standard" — a moat endorsement for the leader. 𝕏

• WFE demand could explode — "like adding another TSMC" (@jukan05, ≈915 likes / 64 reposts): "UBS's bold call: SPCX's Terafab could spend $50B on WFE in 2030/2031 alone — basically adding another TSMC. If real, we should be buying WFE right now." 𝕏

• Adding growth leaders (@HappyBullTrader, ≈2 likes / 34 views): "I picked up $CELH $NVDA $NFLX 👍" — representative of retail bullishness. 𝕏

• Memory modules strong, H2 growth intact (@livermoerR, ≈128 views): "ADATA and other memory-module makers posted strong June revenue; Micron is lifted by AI-server demand and rising memory prices; module makers, aided by low-cost inventory plus pricing gains, should sustain high growth into H2." 𝕏

Bearish / cautious

• Nasdaq 100 down over 1%, chip drag (@KobeissiLetter, ≈2,304 likes / 279 reposts / 251k views): The window's highest-engagement event/bear post, pinning the decline on the chip pullback. 𝕏

• Worried memory becomes a "funding short" like Nvidia (@jukan05, ≈510 likes / 18 reposts): "I'm worried memory could become a funding short like Nvidia — fundamentals keep making new highs while the stock just moves sideways. Could memory follow the same path?" — the core doubt on the durability of the storage rally. 𝕏

• From SaaSpocalypse to AI-chip bubble in 24 hours (@PatrickMoorhead, ≈97 likes / 10 reposts): "We swing from the SaaSpocalypse to AI chip bubble bursting and software now cool in 24 hours. Sure." — mocking the whipsaw of market narratives, a jab at the day's "AI-chip bubble" scare. 𝕏

• Nasdaq relative weakness vs. S&P (@WyckoffAnalysis, ≈1 like / 920 views): "The Nasdaq continues to show relative weakness compared with the S&P 500" — a bearish technical tilt. 𝕏

• A bearish brew for US equities (@CEOTechnician, ≈7 likes / 1,290 views): "A Bearish Brew For US Equities," naming $SPX $MU $SPY — a technical bear read. 𝕏

• Nasdaq-100 bear markets increasingly frequent (@OddStats, ≈33 likes / 3,065 views): "There have been 8 bear markets on the Nasdaq-100... 4 in the past 8 years. So either we're not due for a decade, or they're happening a lot more often." 𝕏

• TSMC faces Samsung foundry challenge (@dnystedt, ≈73 likes / 8 reposts): Samsung's foundry backlog up to KRW 50T with Meta/Anthropic eyeing Samsung 2nm — a marginal negative for TSMC's dominance. 𝕏

Hong Kong / A-shares / China ADRs

Bullish / structurally optimistic (event catalysts)

• Oil, semi packaging/testing, PCB and Apple chain all firing (@cnfinancewatch, July 8 pre-market): "US ends Iran oil-sanctions waiver → oil sector opens higher"; "Huatian Technology top of the net-buy leaderboard at RMB1.577B, semi packaging/testing leads net inflows"; "Kingboard issues another laminate price-hike letter, PCB chain price pass-through continues"; "Apple's first foldable iPhone into mass production, Apple-chain foldables ignite." 𝕏

𝕏

Bearish / cautious

• A-shares may pull back near 3,800, short-term "dead time" (@cnfinancewatch, ≈49 likes / 2 reposts / 58.8k views): "This round A-shares need to pull back to roughly 3,800... the coming period may be junk trading time; tech won't truly regather energy until year-end; the rebound is tech bulls' last chance." — a short-term bearish tilt. 𝕏

• HSI futures still in a bearish trend, hold shorts (@BusinessTodayM1, ≈70 views): "HSI futures could extend the rebound, but the broader bearish trend remains intact and we continue to recommend holding short positions." 𝕏

4. Buzz & Sentiment Shifts

• US semis/storage ($MU / $NVDA / $SMH / Samsung): Still the undisputed center of volume and divergence, but sentiment turned notably cautious versus yesterday. Bulls cite Samsung's +1810% Q2 profit, a 20% DRAM hike, module-maker price strength and UBS's WFE call; bears cite Micron's -4.7% close, @jukan05's "memory as funding short," @PatrickMoorhead's "AI-chip bubble" jab, and Samsung's foundry challenge to TSMC. Sharp internal dispersion (NVDA green, MU red) replaced yesterday's broad rally, with buzz staying elevated and bull-bear tension rising.

• US broad market ($SPX / $QQQ): Nasdaq leading lower, CAPE above 40x and rising NY Fed inflation expectations combine to weigh on risk appetite; @RyanDetrick's "breadth at new highs, bull alive" offsets @KobeissiLetter's "Nasdaq down over 1%" and @OddStats' "bear markets increasingly frequent." With the market "awaiting Fed minutes and weighing Middle East tensions," sentiment shifted from bullish to neutral-cautious.

• Hong Kong / China ADRs: Hang Seng closed -0.51% with no standalone catalyst and thin authoritative coverage; @BusinessTodayM1 keeps a bearish HSI-futures stance. Buzz eased further from last week; sentiment neutral-to-soft.

• A-share linkage: @cnfinancewatch dominated volume, anchoring on "oil (Iran waiver ends) + semi packaging/testing (Huatian/Tongfu) + PCB price hikes + Apple-chain foldables," bullish at the event level; but cautious on the index ("pull back to 3,800, dead time"), resonating with the US semis "bubble/sideways" worry.

5. US Options Flow

Key reads

• Micron (MU) — a two-way pre-earnings bet: MU took multiple top-premium slots on 3-day-to-expiry contracts (implying earnings are imminent), with $920/$930/$950/$1000 calls and $900 puts surging simultaneously at IV of 118-121%; Call $920 vol/OI hit 36.3 and Call $925 reached 95.0. This is classic pre-event two-way pricing — the market betting on a big move rather than a direction. Combined with MU's -4.7% close and the KOL clash of "memory as funding short vs. Samsung's profit surge + DRAM hike," the intensity is high.

• Nvidia (NVDA) — counter-trend medium-term calls: Against a Nasdaq-led, chip-wide selloff, the $195 (73d, $73.6M premium — largest on the board) and $200 (10d, ~70k contracts) calls still surged with vol/OI of 2.5, alongside NVDA's +0.7% green close — reflecting continued bets on medium-term leader upside, echoing Cramer's "everything still revolves around Nvidia."

• Tesla (TSLA) — downside puts built into the drop: The $430 puts (3d, vol/OI 9.0) surged after TSLA's -4% close — in-the-money directional/hedge positioning, a bearish near-term tilt.

Overall sentiment: The market-wide put/call premium ratio is 0.88 (<1, slightly bullish), but structurally "MU two-way and NVDA counter-trend calls on single names + SMH/SPY index put hedges" coexist — not one-sided optimism, but a cautious bull keeping leader upside while hedging sector and index risk into a tech pullback, Micron's earnings and the Fed minutes.
