Screening Stocks by Volatility, Recent Top-Trader Lists, and Institutional Holdings

Summary

This Chinese stock-selection post proposes combining three filters: prior-day price amplitude above 1%, appearance on the previous day’s top-trader list, and evidence of institutional buying or holdings. Its rationale is that elevated movement may create opportunities, top-trader activity signals notable capital flows, and institutional interest could indicate perceived value. It offers illustrative screening logic and code references, but reports no backtest results or performance evidence.

The post cautions that simulated returns can differ from live trading, institutional purchases do not guarantee a rise, and top-trader activity may be affected by manipulation. It suggests adding volume, valuation, financial, market, and news information, while using risk controls and capital management. The thresholds and data definitions are not fully consistent across the examples, and the post does not specify a tested holding period, transaction costs, or a validation method. The screen should therefore be treated as a proposed heuristic rather than evidence of a profitable strategy.

Key ideas

• The proposed screen combines price amplitude above 1%, previous-day top-trader-list activity, and an institutional-interest condition.
• The post interprets volatility and top-trader activity as possible signals, while acknowledging that neither guarantees future gains.
• It recommends adding financial, market, volume, valuation, and news factors to strengthen selection.
• Backtest and live results may differ, so risk controls and capital management are advised.
