This paper studies the predictability of ultra high-frequency stock returns and durations to relevant price, volume and transactions events, using machine learning methods. We find that, contrary to low frequency and long horizon returns, where predictability is rare and inconsistent,...

We test and compare the effects of introduction of two new financial information technologies, EDGAR and XBRL, on well-known asset pricing anomalies often attributed to mispricing. EDGAR facilitates easier access to public accounting information about public firms; XBRL reduces the cost of...

Hirshleifer, David; Shi, Yushui; Wu, Weili - National Bureau of Economic Research - 2022

We examine how sell-side equity analysts strategically disclose information of differing quality to the public versus the buy-side mutual fund managers to whom they are connected. We consider cases in which analysts recommend that the public buys a stock, but some fund managers sell it. We...

We propose a tractable model of an informationally inefficient market featuring non-revealing prices, no noise traders, and general assumptions on preferences and payoff distributions. We show the equivalence between our model and a substantially simpler model whereby investors face...

Gandhi, Mihir; Gormsen, Niels; Lazarus, Eben - National Bureau of Economic Research - 2023

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...

Complexity in Factor Pricing Models

Didisheim, Antoine; Ke, Shikun; Kelly, Bryan T.; … - National Bureau of Economic Research - 2023

We theoretically characterize the behavior of machine learning asset pricing models. We prove that expected out-of-sample model performance--in terms of SDF Sharpe ratio and test asset pricing errors--is improving in model parameterization (or "complexity"). Our empirical findings verify the...

Harvey, Campbell R.; Mazzoleni, Michele G.; Melone, … - National Bureau of Economic Research - 2025

Institutional investors engage in trillions of dollars of regular portfolio rebalancing, often based on calendar schedules or deviations from allocation targets. We document that such rebalancing has a market impact and generates predictable price patterns. When stocks are overweight, funds sell...

A Quantity-Based Approach to Constructing Climate Risk Hedge Portfolios

Alekseev, Georgij; Giglio, Stefano; Maingi, Quinn; … - National Bureau of Economic Research - 2022

We propose a new methodology to build portfolios that hedge the economic and financial risks from climate change. Our quantity-based approach exploits information on how mutual fund managers trade in response to idiosyncratic changes in their climate risk beliefs. We exploit two types of...
