Screening Chinese Stocks for Volatility, Turnover, and Three Limit-Up Days

Summary

This Chinese equity screen combines a daily amplitude threshold, a turnover-rate band, and a requirement that the stock had three consecutive limit-up sessions as of the previous day. It frames amplitude and turnover as measures of trading activity, with the streak serving as a signal of strong market attention and momentum. The article also includes example indicator logic and a Python illustration for applying the filters.

The method is explicitly speculative: it selects on short-term price action and trading activity without checking company fundamentals or financial condition. The article warns that the streak can reflect artificial hype and that buying after a sharp run-up can leave traders caught in a reversal. It suggests adding moving-average or MACD filters, fundamental and financial analysis, and disciplined position sizing and exits. It provides no backtest, performance evidence, or quantified risk analysis, and its sample implementation should be checked against the intended definitions of turnover and consecutive limit-up sessions before use.

Key ideas

• The screen requires amplitude above 1, turnover above 2% and no more than 9%, and a three-session limit-up streak ending the previous day.
• It treats turnover and amplitude as trading-activity filters and the streak as a short-term momentum signal.
• The approach is speculative because it does not assess company fundamentals or financial condition.
• The article cautions that hype and chasing a sharp rise can lead to losses.
• It recommends adding other filters and managing position size and exits, but provides no performance test.
