I'm wondering if there are others that have thought through whether to focus on specific sectors or be a generalist. Particularly those that trade solely on fundamentals. I've been a successful REIT trader for many years and believe my expertise in the sector is my edge. Though I remain profitable, I'm finding fewer good opportunities these days and it has been difficult to put all my money to work (and remain reasonably diversified). I'm considering going with a more generalist focus, but it seems hard to get a fundamental edge without being an expert in other sectors. Any thoughts?
