Bridgewater Research: Drivers of U.S. Stock Outperformance and Conditions Needed for Future Repeats

Bridgewater research indicates that since 2010, the excess returns of U.S. stocks relative to developed markets have been roughly equally driven by revenue growth, margin expansion, and rising P/E multiples, with a stronger U.S. dollar further boosting returns for unhedged global investors. The technology sector contributed 54% of the excess returns, of which 22% came from index overweights in technology and 32% from U.S. tech companies significantly outperforming their global peers.
