Size and momentum profitability in international stock markets
Schmidt, Peter S.; Arx, Urs von; Schrimpf, Andreas; … - 2015 - This version: August 25, 2015
We study the link between the profitability of momentum strategies and firm size, drawing on an extensive dataset … covering 14 stock markets across the globe. International momentum profitability is markedly higher in medium-size than in big … stocks. Momentum premia are considerably diminished by trading costs, when taking into account the actual portfolio turnover …

Has the pricing of stocks become more global?
Petzev, Ivan; Schrimpf, Andreas; Wagner, Alexander F. - 2015
We show that in recent years global factor models have been catching up significantly with their local counterparts in terms of explanatory power (R2) for international stock returns. This catch-up is driven by a rise in global factor betas, not a rise in factor volatilities, suggesting that the...

The acceleration effect and gamma factor in asset pricing
Ardila, Diego; Forró, Zalán; Sornette, Didier - 2015
We report strong evidence that changes of momentum, i.e. "acceleration", defined as the first difference of successive … returns, provide better performance and higher explanatory power than momentum. The corresponding Γ-factor explains the … momentum-sorted portfolios entirely but not the reverse. Thus, momentum can be considered an imperfect proxy for acceleration …

Machine Learning and the Implementable Efficient Frontier
Jensen, Theis Ingerslev; Kelly, Bryan T.; Malamud, Semyon; … - 2022
We propose that investment strategies should be evaluated based on their net-of-trading-cost return for each level of risk, which we term the "implementable efficient frontier." While numerous studies use machine learning return forecasts to generate portfolios, their agnosticism toward trading...

A theory of scenario generation
Schneider, Paul - 2019
We show how distributions can be reduced to low-dimensional scenario trees. Applied to intertemporal distributions, the scenarios and their probabilities become time-varying factors. From S&P 500 options, two or three time-varying scenarios suffice to forecast returns, implied variance or...

Moment component analysis : an illustration with international stock markets
Jondeau, Eric; Jurczenko, Emmanuel; Rockinger, Michael - 2010
It is well known that non-normality plays an important role in asset and risk management. However, handling a large number of assets has long been a challenge due to the curse of dimensionality. We describe a statistical technique, which we call Moment Component Analysis (MCA), that extends...

Volatility spillovers, asymmetry and extreme events in securitized real estate returns
Hoesli, Martin; Reka, Kustrim - 2010
This paper analyzes the relationships between local and global securitized real estate markets, but also between securitized real estate and common stock markets. First, the volatility transmissions across markets are examined using an asymmetric t-BEKK (Baba-Engle-Kraft-Kroner) specification of...

The exchange rate effect of multi-currency risk arbitrage
Hau, Harald - 2012
This paper (i) proposes a simple multi-currency model of speculative foreign exchange (FX) trading, (ii) uses a natural experiment to identify the implied components of the optimal trading strategy, and (iii) proposes a new spectral inference method to strengthen the statistical evidence on the...

Dynamic Currency Hedging with Ambiguity
Polak, Pawel; Ulrych, Urban - 2021
This paper establishes a general relation between investor's ambiguity and non-Gaussianity of financial asset returns. Based on that relation and utilizing a flexible non-Gaussian returns model for the joint distribution of portfolio and currency returns, we develop an ambiguity-adjusted dynamic...

Ambiguity and the home currency bias
Ulrych, Urban; Vasiljević, Nikola - 2020 - This Version: August 2020
This paper addresses the question of optimal currency exposure for a risk-and-ambiguity-avers international investor. A robust mean-variance model with smooth ambiguity preferences is used to derive the optimal currency exposure. In the theoretical part, we show that the sample-efficient...
