Abstract

Using unique data on TSX Attributed Trading and a new proxy of Tobin’s Q that accounts for intangible capital (Peters and Taylor, 2017), we investigate the impact of anonymous trading (AT) on managers’ ability to obtain informative feedback from the stock market to improve investment efficiency. We show that AT reduces investment efficiency and that both anonymous buyer-initiated and seller-initiated trades have comparable effects. The negative effect of AT on managerial learning from stock prices is significant for both buyer- and seller-initiated trades but is significant only for tangible investments. Taken together, our new evidence indicates that AT distorts investment sensitivity to Tobin’s Q, plausibly because anonymity attracts additional (uninformed) liquidity trading, which negatively impacts the effectiveness of asset price in aggregating private information and in revealing fundamentals.
