"Mortgage REITs endured a very rough period during March. The index plunged by more than 50%. In April, we saw a resurgence as mortgage REITs rallied from incredibly large discounts to book value. In May, share prices have been relatively weak and opportunities have been growing again. We don't expect a full repeat of March and see a significant upside built into the sector already due to the low price-to-book ratios."
