Using Search Sentiment to Rotate Between Chinese Equity Indices

Summary

This research summary proposes using online search interest about large-cap and small-cap stocks as a proxy for investor sentiment. It argues that changes in this attention measure are positively related to market moves and may lead them, then uses sentiment changes as a timing signal to rotate between Chinese equity indices. The motivation is that internet data may add information beyond factors built from financial statements and market prices, whose shared inputs can contribute to crowded trades.

The summary reports historical results for two rotations: Shanghai 50 versus CSI 500, and CSI 300 versus CSI 500. It gives annualized returns of 29.35% and 15.84%, respectively, with information ratios of 1.80 and 1.48. These figures are reported without the underlying test period, construction details, transaction costs, or robustness checks in the provided text. The authors caution that the analysis extrapolates from past data, and that future market conditions may differ.
