Boosting the Equity Momentum Factor in Credit
Investors can double alpha in the credit markets by using simple equity momentum strategies enhanced by applying machine learning with boosted regression trees.
Machine learning techniques have gained popularity in recent years but only to a limited extent in fixed-income research. This article shows some new work in the application of “boosted regression trees” for the equity momentum factor in the corporate bond market. We report significant performance gains to investors from using machine learning–driven forecasts, roughly doubling the alpha and information ratio of better known equity momentum strategies. In addition to past equity returns, we include size and liquidity of stocks and bonds in our model framework.
