Combining Market Risk Filters, Stock Timing, and Conditional Averaging

Summary

This BigQuant strategy tutorial outlines a framework for combining a broad-market risk signal with individual-stock timing and position management. The proposed workflow builds separate feature expressions for index-level risk and stock-level conditions, connects and arranges the resulting data, and uses the backtest engine to make decisions about holding, selling, or adding to positions. It also describes preparing data on holdings and handling unfilled orders before the market opens. One example uses a comparison of five-day and ten-day average index volume as a market-wide sell-risk indicator.

The approach is aimed at strategies that may hold stocks for several days or longer, where both market exposure and individual positions need ongoing management. The post explains how the signals fit into a platform workflow, but the excerpt provides no completed stock-level rules, performance results, or validation of the example indicator. Its proposed handling of limit-up holdings and averaging into selected stocks therefore requires explicit rules and independent testing, especially because the market signal may not reliably anticipate losses.

Key ideas

• The framework combines a broad-market risk signal with separate timing rules for individual stocks.
• A five-day versus ten-day index-volume average comparison is presented as an example market-risk feature.
• The backtest workflow includes data preparation, position-state checks, and pre-market handling of unfilled orders.
• Stock-level signals may trigger selling or adding to positions, while the market signal may guide overall exposure.
• The excerpt provides no performance evidence or validation for the proposed rules.
