3. KOL Bull & Bear Views

US market & big tech

Bullish

• @RyanDetrick (≈100 likes): "The stock market has never peaked for the year in June… One small gain tomorrow and we are back at ATHs"; separately noted manufacturing at a 4-year high and recommends overweight equities, underweight bonds (≈119 likes). 𝕏¹ 𝕏²
• @MrMikeInvesting (≈43 likes): relaying BlackRock's Larry Fink calling for a 12-month bull run — "the technological revolution is going to power better profit margins." 𝕏

• @Biz_zatukora (≈33 likes, Japanese): PLTR's growth-rate curve is "the most striking chart" — possibly AI's biggest beneficiary. 𝕏

Hong Kong & China assets

Bullish

• @chad_ventures (≈41 likes): HSI forming a monthly cup-and-handle — "29,000 is the neckline to break"; long-term upside for Chinese stocks. 𝕏

Bearish / Cautious

• @michaelxpettis (≈76 likes): quoting commentary that "as long as external demand holds up, policymakers appear relatively untroubled by weakening domestic demand"; also quoting Yuekai's Luo Zhiheng on the economy's policy-dependent "U-shaped rhythm" with weak organic momentum (≈65 likes). 𝕏¹ 𝕏²
• @ChinaBeigeBook (≈12 likes): its survey points to weakness so broad that official retail figures "appear to paint a stronger picture than conditions on the ground." 𝕏
• @cnfinancewatch (≈25 likes, mixed): US/A-share hard tech likely "bottoming and oscillating — the big-drop phase is mostly over," but "don't touch" AI hard tech; HK internet ETFs, innovative drugs and consumption "worth a closer look." 𝕏

4. Buzz & Sentiment Shifts

• US market / Mag-7: chatter well above normal, structurally bullish (~7:2 bull/bear) — driven by the Dow's record close, outsized earnings beats (+27%/+55%) and Larry Fink's bullish call; @KobeissiLetter's index posts drew thousands of likes each. Versus the weekend's wait-and-see mood, sentiment has clearly rotated toward chasing strength; the main dissent is Bianco's long-running inflation-forecast skepticism and the Bezos sale.
• PLTR: the after-hours print was the single hottest ticker of the day (multilingual feeds flooded), almost uniformly bullish — focus on +150% US commercial growth and the raised guide; a classic earnings-driven heat spike.
• GME: high heat, deeply split sentiment — "Trust the Plan" bulls vs. sarcastic bears, while the stock actually fell 12.25%; the narrative-vs-tape divergence widened.
• Hong Kong: absolute volume remains light (media searches surfaced almost no HSI-specific posts), but the mix is shifting: technical KOLs posted bullish breakout setups for a second day, and the Stock Connect expansion adds a policy tailwind — "technicals + policy" double-bullish, against persistent macro caution from Pettis/ChinaBeigeBook (~55% bull / 25% bear). On the tape, HSI edged up 0.48%, Alibaba-W jumped 7.01% and Tencent gained 3.20%, consistent with the "look at HK internet" view.

5. US Options Flow

(Post-close scan of 162 liquid names, as of Aug 3 close; market-wide put/call premium ratio = 0.52, clearly bullish)

Deep dives:

1. MSFT — the day's heaviest bullish positioning. MSFT closed +4.93% at $487.65, and three call lines totaled over $300M in premium: the $510 call (74d) with vol/OI of 215.5 is almost entirely fresh positioning — pricing in another 5%+ rally over 2.5 months right after a new leg higher; combined with heavy 18-day $460/$500 call volume, money is crowding into the software giant's momentum on earnings-season strength — a "strength begets strength" bet, not a hedge.
2. SPY $620 puts (Nov) — systematic insurance at the highs. With the S&P 500 ~20 points from a record, 150k puts ~18% below spot ($758) were opened in one day (vol/OI 208.7). The depth of the strike and the length of the tenor say this isn't short-term bearishness — it looks like institutions buying tail-risk protection at index highs, a telling contrast with X's one-sided bullishness: chase the cash market, hedge in options.
3. TSLA ultra-short-dated at-the-money puts. ~37k contracts across the $320/$322.5 2-day lines, vol/OI above 50, IV 55–56%. TSLA closed +3.49% at $322.08, with strikes hugging the close — traders are paying rich IV for two days of downside exposure, either event hedging or a short-term pullback punt; watch for a TSLA catalyst this week.

Overall: the market-wide put/call premium ratio of 0.52 shows options money leaning clearly bullish, consistent with the cash market's record-high risk appetite — but the large fresh opening of far-OTM long-dated SPY puts signals smart money hasn't abandoned tail hedges at these levels.
