Technical Analysis Around the World

Abstract:
Technical analysis is not consistently profitable in the 49 countries that comprise the Morgan Stanley Capital Index once data snooping bias is accounted for. There is some evidence that technical trading rules perform better in emerging markets than developed markets, which is consistent with the finding of previous studies that these markets are less efficient, but this result is not strong. While we cannot rule out the possibility that technical analysis compliments other market timing techniques or that trading rules we do not test are profitable, we do show that over 5,000 trading rules do not add value beyond what may be expected by chance when used in isolation.
