Improving RSRS Index Timing with Weighted Regression and Signal Damping

Summary

This review evaluates an RSRS market timing strategy out of sample across several Chinese broad-market indices from March 2017 to November 2019. It reports generally positive timing results, strongest on the CSI 300, while the CSI 500 results were more modest. The strategy also tended to outperform or reduce drawdowns relative to the index on several other benchmarks, according to the document.

The report identifies choppy markets as a weakness: signals trigger more often and become less reliable, with win rates falling sharply for the SSE 50 and ChiNext in the 2019 range-bound period. It tests weighted regression variants, finding that time-based weights did little to improve results and turnover-based weights helped mainly on the CSI 500 and ChiNext. A damped RSRS measure incorporates return volatility to reduce false signals in sideways markets; the report says this improved timing across indices. These are historical findings from a particular sample, and the document does not establish that the changes will generalize to other periods or trading conditions.

Key ideas

• The report assesses RSRS timing out of sample across multiple Chinese equity indices.
• RSRS signals became less stable and more frequent during sideways markets.
• Time-distance weighted regression did not materially improve the reported timing results.
• Turnover-weighted regression helped some smaller-index results but had limited benefit on large-cap indices.
• A volatility-informed damped RSRS indicator reportedly reduced false signals across the indices.
