Chinese Stock Screen for High Amplitude and Institutional Buying Signals

Summary

This Chinese stock-selection note proposes screening for shares with daily amplitude above 1, signs of large-player control on the prior day, and an institutional buying signal. It presents the combination as a way to find volatile stocks that may have near-term opportunity. The article offers a brief rationale but no backtest, performance figures, or evidence that these signals predict returns.

Its example Python filter adds conditions for trading volume, amplitude, turnover, nonnegative price-to-earnings and price-to-book values, circulating market capitalization relative to total capitalization, and positive holder counts. These implementation details do not directly encode the stated institutional buying or prior-day control signals, so the example does not fully reproduce the described screen. The note identifies difficulty interpreting institutional activity as a risk and suggests including financial, market, industry, and technical analysis. It provides no rules for position sizing, entry timing, or exits.

Key ideas

• The proposed screen combines amplitude above 1 with prior-day large-player control and institutional buying signals.
• The article frames volatility and institutional activity as potential clues to short-term opportunity.
• The sample Python filter adds turnover, valuation, capitalization, and holder conditions that differ from the stated signal logic.
• Institutional behavior may be difficult to interpret, and the note provides no performance evidence.
• The author suggests adding fundamental, market, industry, and technical analysis.
