  • CXO profit-taking: Asymchem -8.2% after a 20% week, WuXi Bio -4.4% — no fresh negative, just profits leaving

  • Tesla at $391.06 sits 0.27% from the $390 stop into 7/22 earnings — trim Monday if still pinned; don't bet against a gap

Long
Score7/10The 50-day exam Level yesterday; 0.8% below the line this morningThis morning -1.6% — relatively firm in the risk-offWeek +4.5%Stop HK$108Position P&L ~+15% since inclusion

Technicals — Down 1.6% this morning at HK$115.00, 0.8% back under the 50-day (HK$115.89). The RSI-7 at 73.7 bleeds off its heat into the dip; the HK$110 round number and gap form second support with the HK$108 stop beneath — structure intact, exam merely postponed.

Fundamentals — The ~45% cloud-growth preview and the Qwen 3.7 flagship suite (Qwen3.7-Max/Plus) keep the re-rating case unchanged. WAIC 2026 opens in Shanghai today (7/17–20) — a dense catalyst window that resupplies Alibaba's narrative, even as it turns 'news to sell' for the already-run AI model names like MiniMax.

News — No company news; with the Hang Seng opening lower on the US tape, its -1.6% ranks among the book's most resilient — week two of the AI re-rating, and the money hasn't left.

Short-term · 1–3 weeks
Long Bullish

An external pullback (US chips) doesn't overrule the internal case (cloud + AI re-rating); a position stopped above cost can afford to wait for the exam to reopen, with four days of WAIC as potential narrative resupply.

Entry Hold with the HK$108 stop unchanged; a volume reclaim of HK$116 (the 50-day) restarts the advance, and a quiet HK$110–112 retest is the boarding zoneStop HK$108Target HK$130
