We propose a novel specification strategy using a SVAR identified with zero and sign-restrictions to uncover real-time financial shocks in an emerging market. By adding a foreign exogenous block and differentiating between local and US risk premia, we build on the literature that employs...

We show that immediate and delayed abnormal returns following earnings announcement surprises differ across market states. Immediate abnormal returns are more sensitive to earnings surprises in down markets, while delayed abnormal returns are less sensitive; underreaction is attenuated in down...

We study the interaction between ETF rebalancing and hedge fund “front-running” trades and its implications for the capital market. First, we document that ETF rebalancing has a strong negative relation with future stock returns. Second, we observe that hedge funds gradually increase...

I find that hedge funds are unique: they anticipate analyst reports, and then reverse their positions after analysts publish reports. These trends are strongest for hedge funds and analysts most...

We measure investors' short- and long-term stock-return expectations using both options and survey data. These expectations at different horizons reveal what investors think their own short-term expectations will be in the future, or forward return expectations. While contemporaneous short-term...
