We use intraday data to estimate the daily foreign exchange exposure of U.S. multinationals and show that macroeconomic news affects these firms' foreign exchange exposure. News creates a substantial shift in the joint distribution of stock and exchange rate returns that has both a transitory and a persistent component. For example, a positive domestic demand surprise, as reflected in higher-than-expected nonfarm payroll, increases the value of the low-exposure domestic activities and results in a persistent decrease in foreign exchange exposure.
The choice of weighting method in constructing an equity portfolio affects not only the financial performance, but also its Shariah-compliance. We show how the implicit bets in market capitalization, fundamental value, equal and low risk weights can affect the individual's perception of Shariah compliance of the financial portfolio. For the universe of Shariah-compliant S&P 500 stocks over the period 1986-2014, we find that the risk-adjusted performance is improved when using the alternative weighting methods compared with the traditional use of market capitalization weighting. The choice of weighting method matters for the Shariah-compliant equity investor, both in terms of compliance with the primary objectives of Shariah investing and in terms of the secondary objective of optimizing the financial performance of the portfolio.
Les stratégies d’assurance CPPI sont des investissements d’horizon moyen à long terme, qui allouent dynamiquement entre un actif sans risque et un portefeuille d’actifs risqués. Leur objectif est de combiner un potentiel de gain tout en garantissant un capital à l’horizon. Notre article utilise une approche de simulation par bloc pour déterminer si la combinaison de stratégies « smart beta » et l’assurance de portefeuille est utile sous divers scénarios de marché. Nos résultats montrent une amélioration significative de la performance pour le CPPI combiné avec un portefeuille « low-risk ». Ceci est cohérent avec le véga négatif des stratégies CPPI ainsi qu’avec leur dépendance par rapport aux pertes passées.
