Personally, if I were a hedge fund manager, I'd be really careful with this and pick carefully which malls (or rather, the companies that own them) I think are going to fail. The newer, trendy "lifestyle centers" seem to be doing just fine mostly, and even the places like Macy's are still hanging on in some places, just not in others. Macy's isn't going out of business any time soon, but they are downsizing a lot, which means certain locations just aren't viable any more. Even regular malls are still doing OK in many places, but that segment of the market is shrinking.
