Combining Bull-Bear Indicators for Index Timing and Industry Rotation

Summary

The document describes three equity strategies built around a bull-bear indicator: a direct timing rule for broad indexes, monthly indicator-change rotation among industries, and index allocation based on the share of constituent stocks signaling a long position. The direct timing approach adapts the fast-versus-slow logic of moving-average strategies, while the industry approach selects relatively strong sectors and can be combined with market timing. The constituent-based approach scales index exposure according to the proportion of stocks with long signals.

The report gives historical results for Chinese indexes and sectors, including excess returns, a Sharpe ratio, and claims of reduced volatility and drawdown. It says parameter selection was checked using a CSCV overfitting framework and notes that the direct indicator strategy trades more often than a moving-average version. These are reported backtest findings, not guarantees: the excerpt gives limited detail on costs, implementation, data construction, or robustness beyond the stated tests, and the evidence is specific to the examined Chinese equity universe and historical period.

Key ideas

• A direct timing strategy compares short- and long-horizon bull-bear indicators to adjust broad-index exposure.
• Monthly changes in the indicator can rank industries for rotation, with market timing added to manage risk.
• The fraction of index constituents producing long signals can determine the index allocation level.
• The report describes historical excess returns and risk reductions, but these results depend on the tested Chinese equity markets and periods.
• The direct timing strategy trades more frequently than its moving-average counterpart.
