Filtering Volatile Chinese Stocks by Institutional Activity and Auction Turnover

Summary

This Chinese equity screen selects stocks with a daily range above 1%, an institutional participation measure described as exceeding 25% over a 15-day period, and prior-day auction turnover above 0.26. Its final version also requires circulating market value of at least 5 billion yuan. The stated idea is to combine price movement with signals of institutional and broader market attention.

The article recommends adding company fundamentals, considering overall market conditions, and adjusting exposure to manage risk. It offers indicator and Python references, but no backtest, performance evidence, or clear definition for several measures, including “institutional bottom-fishing” and auction turnover. The examples are illustrative rather than a complete validated system; the Python snippet references symbolic fields without showing how they are calculated or retrieved. Because the selection relies on short-term activity and omits operating fundamentals, its candidates may be noisy and sensitive to changing market conditions.

Key ideas

• The screen combines a daily range threshold, institutional participation above 25% over 15 days, and auction turnover above 0.26.
• The final proposed filter adds a circulating market value floor of 5 billion yuan.
• The article frames institutional and trading activity as attention signals, not as demonstrated predictors.
• It recommends adding fundamentals, market context, and exposure controls.
• The supplied examples do not define all measures or report backtest results.
