In empirical tests of the CAPM, the theoretical risk-free asset is typically assumed to be 1-month Treasury bills. This paper examines the implications of a mis-specified risk-free asset, i.e. the possibility that the ‘true' risk-free asset is a longer-maturity Treasury bond. A simple...

This paper makes a breakdown of common Fama-French style equity factor portfolios into their long and short legs. We find that factor premiums originate in both legs, but that (i) most added value tends to come from the long legs, (ii) the long legs of factors offer more diversification than the...

We dissect the realized performance of factor-based equity portfolios using a characteristics-based multi-factor return model. We show that generic single-factor portfolios, which invest in stocks with high scores on one particular factor, are sub-optimal because they ignore the possibility that...

Some exchange-traded funds (ETFs) are specifically designed for harvesting factor premiums, such as the size, value, momentum and low-volatility effects. Other ETFs, however, may implicitly go against these factors. This paper analyzes the factor exposures of US equity ETFs and finds that,...

The low-volatility anomaly is often attributed to limits to arbitrage, such as leverage, short-selling and benchmark constraints. One would therefore expect hedge funds, which are typically not hindered by these constraints, to be the smart money that is able to benefit from the anomaly. This...

The added value of smart beta indices is known to be explained by exposures to established factor premiums, but does that make these indices suitable for implementing a factor investing strategy? This paper finds that the amount of factor exposure provided by popular smart beta strategies...

This paper takes another look at the recommendation of Blitz [2012] to allocate strategically to the value, momentum and low-volatility factor premiums in the equity market. Five years of fresh data shows that such a factor investing strategy continued to deliver out-of-sample. The potential...

The evidence for the existence of a distinct low-volatility effect is mounting. However, implicit exposures to the Fama-French value factor (HML) seem to explain the performance of straightforward U.S. low-volatility strategies since 1963. In this paper I show that the value effect can neither...

In this paper we critically examine the novel concept of fundamental indexation. We argue that fundamental indexation is by definition nothing more than an (elegant) value strategy, because the weights of stocks in a fundamental index and a market capitalization-weighted index only differ as a...

By having the flexibility to take on short positions, so-called 130/30 funds provide classic beta exposure in combination with an enhanced potential for generating alpha. We discuss the main theoretical pros and cons of 130/30 investing and compare various ways in which 130/30 funds are being...
