Current factor models do not identify risks that matter to investors. To address this issue, we provide a factor model implementation of the ICAPM, which captures market risk and intertemporal risk (i.e., changes in long-term expected returns and volatility). We build our intertemporal risk...

The identical cash flow rights of Chinese A and B shares provide a natural experiment that allows us to explore how investor clienteles affect stock return patterns. Chinese domestic retail investors are responsible for the majority of trades in A shares, while foreign institutional investors...

Classical quantitative finance models such as the Geometric Brownian Motion or its later extensions such as local or stochastic volatility models do not make sense when seen from a physics-based perspective, as they are all equivalent to a negative mass oscillator with a noise. This paper...

The active-versus-passive asset debate falsely forces investors into an all-or-nothing decision between the two. Instead, following Margrabe, we use a “better-of-two” option to:(1) calculate the value of active management and,(2) find the optimal weights for an active-plus-passive portfolio...

This paper tells the history of Brazilian stock market returns since the creation of the Ibovespa (the main Brazilian stock market index). From 1968 to 2019, the arithmetic mean real return of the Brazilian stock market is 21.3% per year. The equity premium is 20.1% per year, with a huge annual...

This paper investigates the performance and characteristics of survivor stocks in the S&P 500 index. Using both in-sample and out-of-sample comparisons, survivor stocks outperformed this market index by a considerable margin. Relative to other S&P 500 index companies, survivor stocks tend to be...

Using a comprehensive set of 103 equity strategies, we analyze the value of volatility-managed portfolios for real-time investors. Volatility-managed portfolios do not systematically outperform their corresponding unmanaged portfolios in direct comparisons. Consistent with Moreira and Muir...

We document that the variation in market liquidity is an important determinant of momentum crashes that is independent of other known explanations surfaced on this topic. This relationship is driven by the asymmetric large return sensitivity of short-leg of momentum portfolio to changes in...

We estimate trends in diversification for equity, debt, and real estate within and across countries. After 2000, we uncover a marked and near ubiquitous decline in diversification, which coincides with sharply higher levels of investment risk. This decline is associated with country economic...
