摘要

We propose a novel approach to study if Latin America Stock Markets are Efficient. This test is based on a statistical arbitrage technique known as Pairs Trading, which is a relative value trading strategy consisting in taking a position in a pair of stocks that are chosen to have similar characteristics and taking a long position in one stock and a short position in the other stock. We use an approach introduced in Ramos et al. (2007) based on the evolution of the Hurst Exponent of a pair. We will show how in emerging markets this trading strategy is profitable though it is not in developed markets, which is according with the weak form of efficiency. (C) 2019 Elsevier B.V.
