We discuss various performance measures of beta hedging and offer a new synthetic criterion that accounts for both risk-adjusted return and loss of the trading strategy. We consider two long portfolios hedged by the SPDR S&P 500 ETF (SPY) that mimics the S&P 500 index. The first portfolio...

The authors study whether the pricing of systematic factors depends on the investment horizon over which risk is measured. Market beta and Fama--French value beta are priced when risk is measured over intermediate horizons, while liquidity beta is priced over short horizons. Alpha on a...

By choosing investment strategies that intentionally create exposure to factor betas, investors may be obtaining uncompensated risks. We show across a wide variety of factors and geographical markets that factors constructed from fundamental characteristics have earned high returns, whereas...

In this paper, we tackle the Beta anomaly, namely the fact that high-Beta assets tend to be associated with lower risk-adjusted returns than low-Beta assets, and connect it to mutual funds' expectations. We present a model with two types of investors, mutual funds and hedge funds, with...

Investors’ return on their portfolios, as proxied by the market, is a theoretically appealing but empirically unsuccessful asset pricing factor. In practice, many institutional investors choose to deviate substantially from the market portfolio. We propose a simple model in the spirit of...

In this paper we will try to improve on the Modern Portfolio Theory (MPT) as developed by Markowitz (1952). As a first step, we combine the MPT model with generalized momentum (see Keller 2012) in order to arrive at a "tactical" MPT. In our second step, we will use the single index model (Elton,...

Dynamic beta is a program that dynamically allocates to beta assets based on formal rules. It contrasts with standard mean-variance optimization and static risk-parity approaches, which are static. Dynamic beta lowers the overall risk of the fund — where risk includes volatility of returns...

We considered five risk-based strategies: equally-weighted, equal-risk budget, equal-risk contribution, minimum variance and maximum diversification. All five can be well described by exposure to the market-cap index and to four simple factors: low-beta, small-cap, low-residual volatility and...

In this paper we examine the characteristics and stability of individual stock and portfolio betas of stocks listed in the Istanbul Stock Exchange (ISE) using samples of 500 individual stocks and 500 portfolios of 10 stocks each. We begin with a methodology similar to the basic event study...

CAPM alpha explains hedge fund flows better than alphas from more sophisticated models. This suggests that investors pool together sophisticated model alpha with returns from exposures to traditional (except for the market) and exotic risks. We decompose performance into traditional and exotic...
