FYI: These past several years have not been kind to quantitative-, systematic-based strategies, and the period spanning October 2018 through April 2019 has felt like additional salt thrown onto a festering wound.
This year has seen a strong double-digit advance in stocks recovering from the sell-off in the fourth quarter of 2018. However, this year’s advance has been quite narrow, having been led (once again) by U.S. growth technology stocks (proxied by Nasdaq-100), leaving other sectors, styles, and regions far behind (Figure 1)
