The pale blue line is DRW an ex-US reit fund. It declined, but had been on a tear before the start of this episode. The others moves almost lockstep to the down side. As you can see they've stabilized in the last month.
Yields are:
Symbol Current Yield Price % of 52 Week Range NRO 9.34% 37.6% VNQ 4.68% 24.8% EWRE 1.78% 28.7% WPC 6.42% 24.2% DRW 6.64% 60.8%
There's not very good correlation between yield and depth of decline right now. As you can see some were hurt worse than others but most are at about 25% to 40% of the 52 week price range. Only DRW is better.
