Momentum strategies are based on the observation that assets with the best recent performance tend to outperform the market.

“Curiously, even though the market for nominal U.S. Treasury securities is among the deepest and most liquid in the world, no one has rummaged through government bond term structures to find similar strategies that work, no matter what the future general direction of interest rates,” writes J. Benson Durham, assistant VP of the Federal Reserve Bank of New York’s markets group.
