Research on angel investors is sparse because data are sparse. Most comprehensive studies of angel investors have focused on the US and UK. In these studies, definitions of angel investors and estimates of returns on angel investments vary dramatically. What can we make of this wide range of...

We cross-sectionally analyze the presence of aggregated hidden depth and trade volume in the S&P 500 and identify its key determinants. We find that the spread is the main predictor for a stock's hidden dimension, both in terms of traded and posted liquidity. Our findings moreover suggest that...

This research uses macro factors to explain four standard U.S. stock market risk premia, i.e. the market excess return (RM-RF), size (SMB), value (HML), and momentum (WML). We find in-sample predictive power of macro factors, in particular at a one-year horizon. Differentiating between bull and...

From 1963 through 2015, idiosyncratic risk (IR) is high when market risk (MR) is high. We show that the positive relation between IR and MR is highly stable through time and is robust across exchanges, firm size, liquidity, and market-to-book groupings. Though stock liquidity affects the...

Following Chairman Ben Bernanke’s comments before Congress that the FOMC may ‘take a step down in the pace of asset purchases if economic improvement appears to be sustained’, US 10-year interest rates picked up sharply and gross capital flows to emerging market economies (EMEs) reversed....

Inter-dealer trading in US Treasury Securities is almost equally divided between two similar electronic trading platforms. This provides a natural experiment within which to test the propositions of Bloomfield & O'Hara (1999 and 2000) about price discovery in fragmented markets. We examine the...
