U.S. Stock Computing Power and Storage Sector: Two-Day Tiered Observation Checklist (Market + Fundamental Trading Signals)

1. Day One: U.S. Stock Market Regular Opening Day (Sentiment + Liquidity Verification Day)
Core Purpose: Differentiate overnight liquidity dips from genuine sector fund outflows, only for position defense and trial-and-error judgment, not for medium- to long-term tone-setting.
1. Price Recovery Range (Strongest intra-day signal)
• Healthy Recovery (Liquidity Mispricing)
Recover more than 60% of the overnight decline within the first 30 minutes of opening
Qualitative: Downturn caused by overnight low liquidity, quantitative sell-offs, passive position reduction leading to emotional volatility, with no fundamental damage.
Operation: Continue holding the core position, gradually buy the dip in small lots for trial.
• Weakness Continuation (Ongoing Capital Outflows)
Volume increases throughout the day with continued weakness, hitting new lows, recovery less than 20% of the overnight decline by close
Qualitative: Cross-market position reduction sentiment persists, sector risk appetite continues to decline.
Operation: Pause all adding actions, reduce positions on high-flying stocks, and tighten holdings.
2. Philadelphia Semiconductor Index Quantitative Verification (Sector-Level Confirmation Signal)
Trigger Condition: Trading volume today > 1.5 times the 20-day average volume, and the index closes lower
Qualitative: Confirms systemic deleveraging in the global semiconductor sector, with large-scale fund outflows, shifting from short-term volatility to medium-term valuation digestion.
Operation: Reduce overall semiconductor and AI hardware sector positions, lower sector exposure.
3. Internal and External Market Linkage Strength (Sentiment Clearing Verification)
Track intra-day trends of leading Korean stocks (SK Hynix, Samsung Electronics):
• Korean stocks stabilize without new lows, U.S. stock computing/storage stocks oscillate and stabilize → Short-term panic sentiment fully cleared, market gradually reverts to its own logic.
• Korean stocks continue to decline sharply, sentiment persists → U.S. stocks remain under pressure, volatility risk not over, maintain light positions and observe.
4. Institutional Fund Flows (Safety of Bottom-Fishing Judgment)
Track main/ institutional fund flows in core U.S. stock storage and AI chip stocks:
• Continuous net outflows: main funds not absorbing, no rush to bottom-fish on the left side.
• Narrowing outflows and shifting to mild inflows: reduced divergence in funds, increased probability of market stabilization.
