Testing Strategies from Stock Connect Holdings and Flows

Summary

This research summary examines the validity of mainland China Stock Connect ownership data and describes portfolio strategies built from investor holdings, sector allocations, style exposures, leading trades, and net capital flows. It reports persistent overweights in food and beverage, home appliances, electronic components, and healthcare, alongside a large-cap and momentum tilt. It also describes mostly negative beta exposure and relative underweights in book-to-price, earnings growth, and leverage characteristics.

The summary gives reported backtest excess returns for several approaches and holding periods. The leading-trade and net-flow variants show the largest cited results against the CSI 300 and CSI 500, while sector- and style-based portfolios are also reported to outperform selected benchmarks. These figures are presented without the underlying report's detailed methodology, test dates, transaction costs, risk statistics, or discussion of data availability and look-ahead bias. They should be read as summarized historical backtest claims, not as evidence that the strategies will perform similarly in live trading.

Key ideas
