Using Northbound Flows for Market Timing, Sector Rotation, and Stock Selection
Summary
This report examines whether mainland China’s northbound investor flows can inform A-share trading. It tests flow thresholds for market timing, ranks sectors and stocks by net inflows, and combines sector selection with stock selection. The timing approach adapts its parameters through a rolling analysis from a fixed start point; the portfolio approach selects sectors first and then stocks within them. The report says weekly inflows into the leading sectors and stocks within each industry showed useful signals, while individual-stock inflows were not reliable timing signals.
The reported backtests include a 58.6% timing win rate and 63.53% cumulative return for the timing indicator, compared with a negative return for the CSI 300 over the stated period. A monthly sector-first strategy is also reported to have an annualized return of 35.13% after assumed two-way fees. These are historical results from the report, not guarantees. Fixed flow thresholds are sensitive to parameter choice and become less suitable as flow volatility rises; the findings may also reflect the strong past performance of popular large-cap holdings and favored sectors.
Key ideas
- Northbound fund flows may help time the broad A-share market, but fixed thresholds are sensitive to their calibration.
- A rolling timing indicator is presented as an alternative when flow volatility changes.
- Weekly flows into leading sectors reportedly provided stronger sector-selection signals than monthly flows.
- Individual-stock net flows were not useful as standalone entry and exit signals in the reported analysis.
- Selecting sectors first and then stocks within them is the basis of the report’s combined strategy.
