Using a semi-supervised topic model on 7,000,000 New York Times articles spanning 160 years, we test whether topics of media discourse predict future stock and bond market returns to test rational and behavioral hypotheses about market valuation of disaster risk. Focusing on media discourse...

Active managers have strong incentives to concurrently realize tax losses and window dress portfolios at the ends of calendar quarters. Consequently, stocks with capital losses experience downward price pressure, and a large share of returns to momentum strategies is earned at these times. This...

This contribution studies the out-of-sample performance of trading strategies applying 2-State-Markov-Switching models. Thereby, different probability thresholds are considered where the investor decides when to go in, respectively, out of the stock market. Furthermore, the investor may decide...

In contrast to the seasonality for risky, less visible firms, we found that highly visible stocks display return seasonality that shows the opposite trend. Fund managers are prone to gamesmanship, putting...

We implement a novel approach to derive investor sentiment from messages posted on social media before we explore the relation between online investor sentiment and intraday stock returns. Using an extensive dataset of messages posted on the microblogging platform StockTwits, we construct a...

There are many well documented behavioral biases in financial markets. Yet, analyzing U.S. equities reveals that less than 1.21% of returns are predictable in recent years. Given the high number of biases, why are returns not more predictable? We provide two pieces of new evidence for one...
