Screening Chinese Stocks for Institutional Buying and an Upward 30-Day Average

Summary

This stock-selection idea combines three signals: a stated daily increase in holdings above 5%, a recent institutional buying or bottom-fishing signal, and an upward-sloping 30-day moving average. The accompanying discussion interprets the first two as signs of buying interest and the moving average as a trend filter. It also suggests considering valuation measures such as price-to-earnings and price-to-book ratios, choosing entry and exit timing, and limiting position size.

The article acknowledges that institutional activity and fund flows can be misleading and that an upward trend can reverse. It supplies sample Python intended to calculate moving averages and turnover-based signals, but the code does not clearly implement the stated screening logic: the institutional signal is proxied by turnover, and later conditions use signal counts and a moving-average comparison that do not directly match the prose. No backtest results or evidence are reported, so the proposal should be treated as an outline requiring careful data and code validation.

Key ideas

• The proposed screen combines a daily holdings-increase measure, an institutional buying signal, and an upward 30-day moving average.
• The article suggests adding valuation checks and defining entry, exit, and position-size rules.
• Institutional buying and fund flows do not guarantee future price gains.
• The sample code uses turnover as a proxy for institutional buying and does not clearly match the written rules.
• The document provides no backtest results to establish the strategy's performance.
