I document a new stylized fact: the higher the degree of institutional ownership (IO) in a portfolio, the more time-varying expected returns rather than changes in expected dividend growth drive changes in its valuation. Empirical evidence suggests that institutions' time-varying sensitivity to...

We give an explicit algorithm and source code for constructing risk models based on machine learning techniques. The resultant covariance matrices are not factor models. Based on empirical backtests, we compare the performance of these machine learning risk models to other constructions,...

We analyze the out-of-sample performance of variables shown to forecast future mutual fund alphas. The degree of predictability, as measured by alpha spreads from quintile sorts or by cross-sectional regression slopes, falls by at least half post-sample. These declines appear to be primarily the...

This paper documents a significant time-series momentum effect that is consistent and robust across all examined conventional asset classes from 1969 to 2015. We find that the duration and magnitude of time-series momentum is different in developed and emerging markets, but this is no longer the...

This paper provides evidence of the impact of hedge funds on asset markets. We construct a simple measure of the aggregate illiquidity of hedge fund portfolios, based on the cross-sectional average first order autocorrelation coefficient of hedge fund returns, and show that it has strong and...

This paper uses the correlation of money flow among mutual funds to forecast the skewness of stock returns. We show that asset returns are highly negatively skewed when their mutual fund owners experience correlated liquidity shocks. In addition, stocks with high mutual fund ownership are more...

We provide evidence that institutions place lower trading priority and delay their trading in small, illiquid stocks. The slow trading of small stocks in turn delays the adjustment of small stock prices. In contrast, for large, liquid stocks, institutions demand immediacy, which generates some...

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...

I investigate the importance of local demand shocks on excess comovements and return predictability for 4560 twin-pairs of Exchange-Traded Funds (ETFs) from 15 country-pairs. The returns on ETFs traded in the same country comove excessively with one another. These comovements are stronger for...

This paper proposes and tests an investment-flow based explanation for three empirical findings about return predictability -- the persistence of mutual fund performance, the "smart money" effect, and stock price momentum. Motivated by prior studies, I construct a measure of demand shocks to...
