Edmans, A, Goldstein, I and Jiang, W (2015) Feedback effects, asymmetric trading, and the limits to arbitrage. American Economic Review (AER), 105 (12). pp. 3766-3797. ISSN 0002-8282 OPEN ACCESS

Abstract

We analyze strategic speculators' incentives to trade on information in a model where firm value is endogenous to trading, due to feedback from the financial market to corporate decisions. Trading reveals private information to managers and improves their real decisions, enhancing fundamental value. This feedback effect has an asymmetric effect on trading behavior: it increases (reduces) the profitability of buying (selling) on good (bad)news. This gives rise to an endogenous limit to arbitrage, whereby investors may refrain from trading on negative information. Thus, bad news is incorporated more slowly into prices than good news, potentially leading to overinvestment.
