When 4 quantitative seats appear on the dragon-tiger rankings, it indicates significantly increased market attention and potential formation of short-term hotspots. Enhanced capital coordination provides stronger stock price momentum, but short-term volatility also intensifies, presenting both opportunities and risks. Investors should monitor thematic coordination and price-volume relationships to capitalize on participation opportunities. In terms of future trends, short-term performance may be strong, but caution is needed regarding risks from rapid quantitative fund withdrawals.

**IV. Stocks with 5 or More Quantitative Seats on Dragon-Tiger Rankings**

When 5 or more quantitative seats appear on dragon-tiger rankings, it often signals high market consensus formation regarding specific sectors or individual stocks, becoming focal points for concentrated capital inflows or outflows. Short-term direction becomes relatively clear with significantly increased volatility, and trends may continue, but this often indicates proximity to cyclical peaks. Investors should be alert to liquidation pressure and short-term reversal risks from overcrowded trading structures. While short-term momentum may persist, pullback risks are simultaneously accumulating.
