With the advent in recent years of large financial data sets, machine learning and high-performance computing, analysts can backtest millions (if not billions) of alternative investment strategies. Backtest optimizers search for combinations of parameters that maximize the simulated historical...

Correlation matrices are ubiquitous in finance. Some key applications include portfolio construction, risk management, and factor/style analysis. Correlation matrices are usually estimated from historical empirical observations or derived from historically estimated factors. It is widely...

This paper documents that option-implied tail risk in the U.S. financial sector predicts real economic activity. The predictability is found to be incremental to the information content in a stock price-based measure of financial sector tail risk. This finding holds both in- and out-of-sample...

We prove that high simulated performance is easily achievable after backtesting a relatively small number of alternative strategy configurations, a practice we denote “backtest overfitting”. The higher the number of configurations tried, the greater is the probability that the backtest is...

Futures contracts on the New York Mercantile Exchange are the most liquid instruments for trading crude oil, which is the world’s most actively traded physical commodity. Under normal market conditions, traders can easily find counterparties for their trades, resulting in an efficient market...

The existing weight of evidence suggests that financial structure (the classification of a financial system as bank-based versus market-based) is irrelevant for economic growth. This contradicts the common belief that the institutional structure of a financial system matters. We re-examine this...

This paper studies the impact of stock market development on cross country relative prices (the real exchange rate). A nonlinear relationship is uncovered in the cross section: prices and the stock market increase together in the beginning; then prices fall as the stock market continues to...

This paper re-examines the performance of the "Dogs of the Dow" (DoD) investment strategy in a different market setting and over a different time period. In particular, we use Finnish data over the period 1988-2008 to examine whether the DoD strategy can be successfully replicated in different...

We investigate the link between stochastic properties of exchange rates and differences in capital-output ratios across industrialized countries. To this end, we endogenize capital accumulation within a standard model of exchange rate determination with nontraded goods. The model predicts that...

We investigate the relationship between Value, Growth and two forms of Momentum across a wide range of developed and emerging international equity markets using MSCI total return ‘smart beta' indices. As would be anticipated, Value generally beats Growth. A distinction is then made between...
