It might be hard to tell by the S&P 500’s lethargic first-quarter performance, but the growth and momentum factors continued excelling to start 2018. As measured by the Russell Top 200 Pure Growth Index, domestic large-cap growth stocks returned 4.66% in the first quarter while the S&P 500 Index Momentum US Dollar Gross Total Return gained 3.39%.

The Dorsey Wright US Sector Momentum Index (DWUSSR) is topping the S&P 500 by approximately 160 basis points on a year-to-date basis as of April 18th, indicating that unique approaches to the momentum factor are bearing fruit this year.
