The “workup” mechanism, a trading protocol used in the U.S. Treasury securities market, is designed to mitigate the instantaneous price impact of a trade by allowing market participants to trade additional quantities of a security after a buyer and seller first agree on its price. Nevertheless, workup trades are not necessarily free of information. In this post, we assess the role of workups in price discovery, following our recent paper in the Review of Asset Pricing Studies (an earlier version of which was released as a New York Fed staff report).
