FYI: Momentum is one of the most pervasive forces in financial markets. It has been observed in nearly every market studied. While targeting assets with strong recent performance appears to have been a winning strategy on paper, there are challenges with putting it into practice. It requires high turnover, which can be a lot of work for do-it-yourself investors and can lead to high transaction costs and poor tax efficiency.
