How Trend Following Strategies Shape Return Distributions [Alpha Architect]

Trading Costs Wipe Out the Overnight Return Anomaly [Alpha Architect]
At least once a year, the press and Twittersphere propagate the mistaken idea that investors can earn excess returns by buying the S&P 500 at the close of the market, then selling it at the open the next day. The logic is that by exposing themselves to only overnight returns, investors can seek
