Summary

This research explores whether online search interest can serve as a timely measure of investor sentiment and help identify shifts between large-cap and small-cap Chinese equities. It treats search activity related to each style as a sentiment proxy, examines its relationship with market moves, and proposes using changes in sentiment to time rotations between indices.

The report gives historical results for two rotations: the Shanghai 50 against the CSI 500, and the CSI 300 against the CSI 500. It reports annualized returns of 29.35% and 15.84%, respectively, with information ratios of 1.80 and 1.48. The supplied text does not detail the test period, signal construction, transaction costs, or robustness checks. The authors caution that the analysis extrapolates from past data and may not hold under different future market conditions.

Key ideas

  • Online search activity is used as a proxy for investor attention and sentiment toward large-cap and small-cap stocks.
  • The proposed timing signal relies on sentiment changes being positively related to market changes and potentially leading them.
  • The strategy rotates between the Shanghai 50 and CSI 500, or between the CSI 300 and CSI 500.
  • Historical results are reported, but the provided text omits details needed to assess the tests fully.
  • Past performance may not persist if market conditions change.
