Intraday Trade-Count Factors for Chinese Equity Selection

Summary

The report develops stock-selection factors from one-minute Chinese equity data, adding transaction counts to price and volume inputs. It examines average trade value and the direction of large-trade activity, then evaluates these signals both alone and alongside an existing multifactor model.

The reported tests find positive selection results for the share of average trade value associated with outflows, including after orthogonalization and controls for common factors. Factors based on net large-trade inflows and large-trade-driven price increases show negative associations with subsequent returns in the reported sample. Adding the intraday factors modestly improves the model’s rank information coefficient, information ratio, and equal-weighted returns for its highest-ranked stocks. These are backtest findings from the report; the supplied summary does not specify the sample period, transaction costs, or robustness across markets, so the results do not establish live-trading performance.

Key ideas

• One-minute transaction counts can augment price and volume data when constructing stock-selection signals.
• The report tests average trade-value measures, including the share of average trade value associated with outflows.
• Large-trade net inflow and price-impact measures are evaluated using the minutes with the largest average trade values.
• The reported factor relationships persist after orthogonalization, though their measured strength is reduced.
• Adding the factors modestly improves the reported multifactor model metrics and top-ranked portfolio returns.
