I investigate whether or not the multi-period trades of financial institutions cause mispricing in the stock market. After controlling for the magnitude and trends in institutional trades, I find evidence consistent with institutional trades pushing prices away from fundamentals. Stocks heavily...

A great proportion of stock dynamics can be explained using publicly available information. The relationship between dynamics and public information may be of nonlinear character. In this paper we offer an approach to stock picking by employing so-called decision trees and applying them to XETRA...

This paper evaluates if sentiment extracted from social media and options volume anticipates future asset return. Using both textual based data and a particular market data derived call-put ratio, between July 2009 and September 2012, this research shows that: 1) features derived from market...

This paper studies the joint dynamics of momentum and reversal strategies in the U.S. stock market. Momentum investors face uncertainty about whether past patterns of price movements will continue (momentum) or reverse, thereby increasing volatilities of momentum returns and occasionally leading...

We correlate analysts' forecast errors with temporal variation in investor sentiment. We find that when sentiment is high, analysts' forecasts of one-year-ahead earnings and long-term earnings growth are relatively more optimistic for “uncertain” or “difficult to value” firms. Adding...

This paper analyzes the life cycles of hedge funds. Using the Lipper TASS database it provides category and fund specific factors that affect the survival probability of hedge funds. The findings show that in general, investors chasing individual fund performance, thus increasing fund flows,...

This paper reveals that in addition to fundamental factors, the 52-week high price and recent investor sentiment play an important role in analysts' target price formation. Analysts' forecasts of short-term earnings and long-term earnings growth are shown to be important explanatory variables...

We examine whether, and to what extent, investors focus on salient and easy-to-process features in responding to analyst forecasts. We focus on rounding as arguably the most salient forecast feature. We find that while rounding is only marginally associated with forecast accuracy, investors...

I estimate a theory-based behavioral momentum using analysts' predictable underreaction (APU) as a proxy for newswatchers underreaction. The results show that APU strongly predicts analysts' errors and, more importantly, stock returns. A long-short strategy based on APU generates a...
