Screening Small Profitable Stocks by Volatility and Large-Order Flow

Summary

This Chinese stock-screening proposal combines daily price range, market capitalization, profitability, and large-order net volume. It looks for stocks whose high-to-low range is at least 1%, whose market value is positive and no more than 10 billion yuan, and whose net profit is positive. The stated rule also requires large-order net volume above 0.05 for at least three days. The article explains these filters as a way to find smaller profitable companies with recent price movement and buying interest.

The post flags that high volatility can bring substantial risk, short-term order-flow readings can miss longer-term trends and company fundamentals, and capital flows can change abruptly. It recommends evaluating trends, valuation, earnings, and institutional flows alongside the initial criteria. Its sample screening code checks a three-day rolling sum against three times the threshold, which does not necessarily verify that each of the three daily readings individually exceeds the threshold. No historical performance evidence or risk-adjusted results are provided, so the proposed growth and investment potential remain untested claims.

Key ideas

• The screen combines a minimum daily trading range with a market-cap ceiling and positive net profit.
• The stated flow filter looks for large-order net volume above a threshold across three or more days.
• High volatility and rapidly changing order flow can increase risk and produce unstable signals.
• The article suggests adding trend, valuation, earnings, and institutional-flow analysis.
• The sample rolling-sum check may not enforce the stated per-day threshold on each of three days.
