D.un and BEI.un both down over 30% in 12 months. While most REITs are down in the last year, D.un and BEI.un are making the others look good by comparison (until a month ago I would have included ONR.un too, but since then it's reversed its downward spiral whereas these two continued down). These 2 seem to be unique in their extreme poor stock performance. Are their problems similar? Would you buy one, both, or neither? Thanks & GLTA.
