This paper aims to examine the Adaptive Markets Hypothesis in six Latin American stock market indices. The results of the bootstrapped versions of the Chow-Denning and Brock, Scheinkman, Dechert, and LeBaron independence tests and the Runs test applied to fixed-length moving subsample windows reveal the linear time-varying adaptability of the Argentinian, Brazilian, Chilean, Colombian, Mexican, and Peruvian stock indices, while the evidence of non-linear adaptability is not strong. The six indices also adapt to specific market conditions, although this varies with each market. There is evidence of adaptability in Latin American stock indices, but investors should view each market independently.
