Finance Seminar（2019-34)

Topic: Buy-Side Competition and Momentum Profits

Speaker: Nagpurnanand Prabhala, The Johns Hopkins Carey Business School

Time: Wednesday, 18 December, 10:00-11:30

Location: Room 217, Guanghua Building 2

Abstract:

We show that a new measure of buy-side competition explains momentum profits. The monthly momentum spread is 1.39% when competition is low and negligible when competition is high. Better alphas are attained with superior Sharpe and Sortino ratios, less negative skewness and in more investible strategies featuring value-weighted portfolios and large capitalization stocks. Stock characteristics traditionally related to momentum do not explain our results. Evidence on long-term returns and the trading patterns of funds, their style peers, distant funds, and retail investors suggest that slow information diffusion and trend chasing explain momentum and its reversal in low competition markets.
