Vincent Deluard finds GDP growth market timing fails to boost stock returns

7 articles · Updated · MarketWatch · Apr 29

Deluard’s analysis, covering 1948–2018, shows even with advance knowledge of quarterly GDP growth, passive buy-and-hold stock portfolios outperformed market-timing strategies by about 1 annualized percentage point.
Even knowing GDP growth a year ahead, market timing only slightly outperformed buy-and-hold, by less than 1 percentage point annually, highlighting the limited influence of economic growth forecasts on stock returns.
Deluard concludes investors should focus more on corporate profit margins and price-to-earnings multiples, as recessions and bear markets often do not coincide and economic data only partly drives stock performance.
