Screening Stocks by Price Range, Turnover, and Trading Value

Summary

The post proposes selecting stocks using three recent market-activity measures: daily high-to-low amplitude above 1, actual turnover between 3% and 28% on the prior day, and prior-day trading value above 60 million yuan. It frames the combination as a way to find stocks with price movement and sufficient trading activity, but gives no empirical test or evidence that these conditions predict returns.

The article supplies example indicator and Python implementations, alongside a warning that turnover and trading value can be noisy proxies and that short-term selection may encourage excessive focus on near-term results. It recommends combining the screen with technical and fundamental information and applying risk controls. The formulas and examples may need adaptation to the data source and the intended date alignment; the post does not define a portfolio construction or exit rule, and its discussion does not establish a measurable advantage.

Key ideas

• The screen combines daily price amplitude, prior-day turnover, and prior-day trading value thresholds.
• The stated turnover band is 3% to 28%, and the trading-value threshold is above 60 million yuan.
• The author warns that activity measures can be noisy and do not by themselves establish investment value.
• The examples provide screening logic, but no tested returns, portfolio rules, or exit criteria.
