Research in behavioural finance has shown the importance of investor sentiment to explain stock market returns. In light of the changes in the media landscape from traditional print media towards social media platforms, this paper analyses and compares the ability of investor sentiment measures...

You're probably familiar, at least in passing, with the 'convexity' of long-term bonds - i.e. that yields dropping 1% produce a bigger price move than yields rising 1%. A significant amount of brainpower has gone into understanding all the ramifications of this convexity in the fixed income...

This paper studies the impact of mandatory portfolio disclosure of mutual funds on the liquidity of disclosed stocks and on fund performance. We consider a theoretical model of informed trading with different mandatory disclosure frequencies. Using a regulation change in May 2004 that increased...

Utilizing monthly aggregate flow data for U.S. equity mutual funds over 1986-2008, we document several new findings on investor behavior. First, we find a strong negative relationship between changes in expected market volatility as measured by the VIX index and net equity fund flows. Second, we...

We show that mutual funds contribute to cross-sectional momentum and excess volatility through positive feedback trading. Stocks held by positive feedback funds exhibit much stronger momentum, almost doubling the returns from a simple momentum strategy. This “enhanced” momentum is robust to...

We explore whether style investing by mutual fund investors contributes to return comovement of stocks in the same style, classified by market capitalization and book-to-market ratio. We find that a stock's comovement with other stocks in its style is significantly greater when this stock is...

We provide novel evidence supporting the notion that arbitrageurs can contribute to return comovement via ETF arbitrage. Using a large sample of U.S. equity ETF holdings, we document the link between measures of ETF activity and return comovement at both the fund and the stock levels, after...

We examine the impact of mandatory portfolio disclosure by mutual funds on stock liquidity and fund performance. We develop a model of informed trading with disclosure and test its predictions using the SEC regulation in May 2004 requiring more frequent disclosure. Stocks with higher fund...

Purpose - This article examines whether deviations from fundamental value or closed-end country fund's discounts or premiums forecast future share price returns or net asset returns. Design/methodology/approach - The main empirical (econometric) tool is a vector autoregressive (VAR) model. The...

We use trade-level data to examine the role of actively managed funds (AMFs) in earnings news dissemination. We find AMFs are drawn to, and participate disproportionately more in, earnings announcements (EAs) that include bundled managerial guidance. When the two pieces of news are directionally...
