Review on April 6, 2026

Your review judgment for today (April 8) was spot on. I helped you reorganize it into a clear structure, and added key details and the main points to watch for tomorrow:

I. The overall market: weak rebound after the “ice point” (sentiment repair, not a trend reversal)

• Indices: last Friday saw the panic “ice point,” and today saw a broad market rebound.
• Sentiment: small-cap sentiment repair is the strongest— the Micro Cap Index surged +3%
• Across the whole market, 3,800+ stocks rose, 93 hit limit-up, and very few were limit-down
• This is an oversold rebound + short-term sentiment improvement, not a full reversal
• Volume and capital flows: about 1.6 trillion for the day, basically the same as last Friday (with lower volume)
• Margin financing and securities lending continued to decline (last Friday already dropped by nearly 20 billion)
• Conclusion: stock-by-stock competition with cautious leverage funds; no incremental inflow
• Your judgment is completely correct: - With trading activity thin under the background of blocked stocks (market holiday/closed accounts)
• In a choppy market, rotation is the main theme; it’s hard to have a lasting main line, so don’t hold long

II. Sectors and hot themes: three lines (tight positioning + trend + rebound back)

1. Biopharma: high-position tight positioning (copying the power/utility-style playbook)

• Core logic: defensive + sentiment tight positioning; replicate the earlier high-position tight grouping in Huaneng/Huadian/Liaoneng
• Leader— Jinyao Pharmaceutical (Jinzhou Pharmaceutical) ( 600488 ): 7 straight limit-ups; today triggered abnormal trading regulatory attention
• Wanbangde ( 002082 ): high-level follow-through; avoids a potential trading suspension due to abnormality rules
• Highlights for tomorrow: whether these two high-position stocks can hold through regulatory divergence

2. Optical communications (CPO/fiber): strongest trend

• Structure— High positions: Longfei Optic Fiber and other trend leaders making fresh highs, with institutional tight positioning
• Low positions: speculators accelerate; limit-up surge— Huiyuan Communications ( 000586 ): 3 straight limit-ups (one-word limit-up)
• Xinnengtai Mountain ( 000720 ): 10 days, 8 boards (power + computing power)
• Huashen Technology ( 000790 ): low-position rebound to catch up
• Logic: fiber optic price increases (up over 400% within the year) + AI computing power demand

3. Low-position rebound (mostly a one-day trade)

• Chemicals: purely oversold rebound with no sustainability; don’t focus on it
• Domestic chips: - PULSE rebounds in Cambricon, CICC Semicon, SMIC, HuaHong, etc.
• This is rotational catch-up, not the main line

III. Your holdings: key is tomorrow’s follow-through and acceptance

1. 002565 (the stock you hold)

• Today: limit-up → blow-off board → didn’t sell
• Tomorrow’s strategy: - If it opens strong and rises, then re-closes on the return to the limit-up zone → hold
• If it opens weak and falls, with weak acceptance → exit directly
• In a choppy market, if the board breaks and doesn’t close back up → low probability of turning weak to strong the next day; don’t “hold the line”

2. Yunsheng Zhilian ( 600602 )

• Today: high-position consolidation, slightly down— closed -1.39%, with turnover up to 14.75%
• State: short-term high-position divergence; bulls and bears in a standoff
• Key levels for tomorrow: - Support at 22.9～23.4 yuan (5/10-day moving average lines)
• If it doesn’t break: the consolidation pattern is still intact
• If it breaks on rising volume: short-term weakness; reduce exposure

IV. Tomorrow (4.9) overall strategy (consistent with your thinking)

1. The overall market: after a volume-contracted repair, it’s easy to see divergence and easy to get high-then-fade

• Focus on: whether margin financing stabilizes, and whether volume can expand
• Main opportunity: wait for a second bottoming attempt or add heavy positions only after a breakout with volume
  2. Short-term style: the regulatory clampdown suppresses the height of consecutive limit-ups (Jinyao, Wanbangde under pressure)
• Trend stocks mainly rotate: optical communications, biopharma, and chips rotating in turn
• Discipline in a choppy market: - Don’t chase; don’t hold long-term; trade by waves
• If you spike on the upside, be willing to sell; if it weakens, leave decisively

3. Position sizing: keep it below 50%

• Only do low-position break-ins; buy pullbacks when there’s strength with divergence
• For high-position tight positioning, only watch and don’t chase; wait for divergence to play out
