Screening Main Board Stocks by Turnover, Gains, and Capital Inflow
Summary
The document describes a short-term China A-share screening rule for main board stocks. It selects stocks with turnover between 3% and 12%, a daily gain above 1% relative to a comparison benchmark, and a measure of increased holdings or capital inflow above 5%. It presents the rule as a way to combine trading activity, price strength, and same-day market flows. Indicator and Python examples illustrate how such a screen might be assembled, though the examples use different comparison calculations and data fields, so their implementation does not unambiguously match the stated rule.
The author notes that requiring same-day inflows can exclude stocks with potential that lack that signal, while short-term price swings can affect selections. Suggested refinements include adjusting thresholds and considering company fundamentals, industry position, or additional indicators. The document provides no performance results, validation, or details on portfolio construction and risk controls; the screen should therefore be read as a selection concept rather than evidence of a profitable strategy.
Key ideas
- The screen combines turnover, daily relative price strength, and a same-day capital-flow condition.
- It limits candidates to main board stocks and uses specified thresholds for each signal.
- The examples provide implementation references, but their calculations do not fully align with one another.
- Short-term volatility and the inflow requirement may exclude otherwise promising candidates.
- The document suggests adding fundamental or technical filters but reports no backtest evidence.
