Cloaked Trading. Lauren Cohen, Christopher Malloy, January 17, 2017, Paper, "Using a novel, proprietary database of micro-level trading activities by asset managers, we show strong evidence of asset managers engaging in strategic trading in order to “cloak” their most valuable trades. This takes the form, for instance, of a manager who sells her entire position of Microsoft on March 30, and then repurchases to re-establish the same position on April 1. This manager will economically be holding the same position throughout, yet without having to publicly signal this position. These cloaked trades earn an abnormal return of 370 basis points in the following month, or over 36% per year." Link
