HK MomentumHK Oversold

New today“Trucks +22%, AIDC gensets +240%, bank targets marching to HK$50 — not one word of the fundamentals turned bad; what turned was the market's mood for paying AI multiples. The fall from a RMB 300B-valuation party back to HK$29.78 isn't value destruction, it's a seasonal change in multiples — and being flagged by the hot and oversold channels simultaneously says the squeeze is mid-slope”

Score7/10Week -14.7%RSI(14) 31.4H1 HDT sales 66.1 万辆 (+22.6%)MS / Jefferies PT HK$47 / HK$50.8

Technicals — Friday's -7.05% on 2.3x volume closed at HK$29.78 for a -14.7% week, RSI 31.4 near oversold; the price sits 21.7% below the 50-day (HK$38), leaving the 200-day at HK$27.3 as the next structural support — hold it and the repair story keeps a floor, lose it and the stock re-prices as a truck cyclical

Fundamentals — June industry HDT sales ran 117k (+19.2%), H1 661k (+22.6%); 1Q26 revenue RMB 62.56B (+8.9%) with profit RMB 3.09B (+13.8%), AIDC large-bore genset volumes +240%, and gas gensets — at roughly 4x diesel margins — bunching deliveries into Q3. Consensus sees FY profit of RMB 14.3-14.7B (+30%): strip the AI multiple and what remains is an earnings-accelerating machine

News — No negative filings 7/15-17 — this is AI-chain liquidation by association. Up ~80% this year on the 'AIDC backup power' narrative to a record RMB 300B market cap in May, it traded this week as an AI-power proxy getting profit-taken; Friday's tape said it plainly, with utility operators rallying while Weichai slid — the market currently files it under crowded AI trades, not defensives

Neutral Sidelines

The dual-channel flag and the extreme fundamentals-price divergence earn it a seat on the watchlist, but until the AI-crowding unwind officially exhausts, knife-catching money is a donation to the market

Entry In a downtrend RSI 31 is an alarm, not an entry; a quiet hold of the 200-day at HK$27.3 is the first probe-able level, and only a reclaim of HK$33 (the old shelf's lower lip) starts the repair clockStop —Target —

Accumulate

An up-cycle in trucks, the AIDC second curve and high-margin Q3 gas-genset deliveries — the 'transformation breakout year' story is underwritten by 30% profit growth

A sustained AI-capex retreat zeroes out the AIDC premium
An interim miss versus the RMB 6.58B consensus triggers a second leg down

Community Voices

股吧 · Bulls call it a mid-cycle growth entry; bears ask what share of profit AIDC actually is and whether it can carry an AI multiple — both are right, which is exactly what an anchor-swap phase looks like

Ticker	Close	Change	Score	Direction	One-line take
2476 HK	HK$215	-10.71%	5	Neutral	Down 10.71% to HK$215 — the PCB darling has shed 46% in a month, ground zero of HK's AI-hardware wreck. RSI 30 is not a buy signal here. Staying away.
1772 HK	HK$37.82	-5.07%	5	Neutral	Down 5.07% to HK$37.82 with lithium off 38% on the month at RSI 22.5 — flat-exiting this position earlier was exactly right. Oversold is not a bottom; no knife-catching.
9696 HK	HK$32.46	-3.62%	5	Neutral	Down 3.62% to HK$32.46 — the other half of the lithium wipeout, -31.6% on the month at RSI 27.5. Capitulation isn't done; look, don't touch.
100 HK	HK$216	-15.62%	5	Neutral	Down 15.62% to HK$216, week two of the joint sell-side love letter failing — down 76% in three months because the market wants cash flow and conventions don't generate it. Stay far away.
148 HK	HK$51.4	-9.59%	5	Neutral	Down 9.59% to HK$51.4 — the copper-clad laminate name is off 47% in a month, guilt by AI-hardware association. Volume at 0.95x says even the panic is exhausted. Watching only.
2382 HK	HK$53.95	-4.34%	5	Neutral	Down 4.34% to HK$53.95 after a -28% month — at 11.7x the Apple-chain name sits in its historical valuation basement. Cheap, but I'm not front-running the bottom. Wait for it to base.
2577 HK	HK$42.3	-11.88%	5	Neutral	Down 11.88% to HK$42.3 — GaN can't escape the broken-IPO wave, -31.6% on the month and -27.2% on the week. Busted listings have no loyalty bid underneath. Pass.
3317 HK	HK$91.1	-8.81%	4	Neutral	Down 8.81% to HK$91.1 — the quant-tech concept has lost 74% in three months. This isn't a pullback, it's a meat grinder. No price makes it interesting. Avoid.
189 HK	HK$12.68	-5.02%	5	Neutral	Down 5.02% to HK$12.68 — with the refrigerant price-hike story dead, the fluorochem name is off 38% in a month. RSI 29.7 means it fell hard, not that it's a buy. Sidelines.
