“Explaining the Realized pre-Announcement Drift”

- Job Market Paper -

I propose a theoretical explanation for the puzzling positive pre-announcement drift that has been empirically documented to occur before scheduled announcements, using as main example the drift before the Federal Open Market Committee (FOMC) meetings. I construct a general equilibrium model of disagreement (difference-of-opinion) where two groups of investors react differently to the information released at the announcement and also to signals regarding this information available between two announcement dates. The model matches consistently key empirical facts such as (1) the upward drift in prices just before the announcement, (2) lower price volatility, before the announcement, followed by higher volatility after the announcement, and (3) low (high) trading volume before (after) the announcement.
Keywords: FOMC Announcements, Difference-of-Opinion, Scheduled Announcements, Sentiment Risk, Optimal Stopping Time.

“Active vs. Passive: Information Acquisition in the Presence of Corporate Governance” with Jinyuan Zhang

We provide a theoretical framework to understand the implications of passive investors' corporate governance on the information acquisition in financial markets. We allow investors to affect a firm's payoff via corporate governance in an otherwise standard information model. Our model highlights that when passive investors increase a firm's payoff, they generate higher information inefficiencies than when they decrease a firm's payoff. We also provide empirical predictions unique to our model,and discuss the policymakers' trade-offs when regulating the participation of passive investors in corporate governance. We close by applying our insights to two critical passive funds' governance issues: ESG policies and product market competition from common ownership...Keywords: Mutual Funds, Passive Investment, Corporate Governance, Information Acquisition, Strategic Complementarities, Conflict of Interests

“A Theory of Momentum Crashes”

We offer an economic mechanism that rationalizes crashes in the momentum strategy. We propose a general equilibrium model of disagreement (difference-of-opinion) where two groups of investors, Speculators and Fundamentalists, trade in the financial market. Disagreement arises because speculators use a spurious signal to learn about fundamentals, whereas Fundamentalists regard it as pure noise. Furthermore, all investors can engage in costly, though infrequent, research to learn about the true fundamental of a firm. The different interpretation of information creates sentiment risk that drives return persistence, which resembles momentum at short-horizons and mean-reversion at long-horizons. Nevertheless, build-ups in disagreement and uncertainty make the fundamentalist investor willing to pay a cost to research a firm and take a glimpse of its true fundamental. The outcome of research on a firm is revealed in the market, generating sharp market-wide rebounds that cause momentum crashes. The model predictions match complementary empirical evidence on momentum crashes.
