His latest book is Efficiently Inefficient: How Smart Money Invests and Market Prices Are Determined

My research focuses on asset pricing and liquidity risk. It shows that a security’s required return is increased by market liquidity risk (as captured by the liquidity-adjusted capital asset pricing model) and funding liquidity risk (as captured by the margin CAPM), and how the interaction of market and funding liquidity can create liquidity spirals and systemic financial crisis. Indeed, when everyone runs for the exit,prices drop-and-rebound, margins increase, and risk management tightens.

These liquidity risk models can help explain equity returns, option prices, bond yields, currency crashes, valuation in OTC search markets, the CDS-bond basis and other failures of the Law of One Price, the effect of unconventional monetary policy such as central banks’ lending facilities, low-beta returns, embedded leveragepredatory trading, shortselling, optimal dynamic trading, and the why markets are efficiently inefficient.

In addition to liquidity risk, my research explores the other "big" factors that drive returns across markets and asset classes: market exposure across asset class, betting against beta, quality minus junk, carry, sizevalue, momentum, and time series momentum. Indeed, safe, high-quality, high-carry, cheap, and upward-trending securities tend to outperform risky, junky, low-carry, expensive, and declining ones. These factors explain the returns of global securities, hedge funds, Warren Buffett, and much more.
