Abstract

News mostly drive overnight returns, whereas investors' trading mostly drives intraday returns. We use this fact to test theories of momentum and reversal with a sample of intraday and overnight return spanning 1926 to 2019. Portfolios formed on past intraday returns display short-term reversal and momentum without long-term reversal. In contrast, portfolios formed on past overnight returns display only long-term reversal. These results are consistent with underreaction theories of momentum, where investors underreact to the information conveyed by the trades of other investors.

Keywords: Momentum, Reversal, Intraday, Overnight, Underreaction
