Best sectors for MM L/S

I'm biased, but I would look for an industry that offers a lot of breadth in terms of companies and subsectors as well as significant and growing market cap. To me, this is basically TMT, Consumer, and Healthcare. I've seen plenty of talented energy and FIG investors unable to really keep pace w/ changing environments as their sectors consolidate, shrink in market cap, and lose much of the dispersion that allowed them to generate alpha in the first place. Definitely not trying to knock these other sectors, especially if it's something you're passionate about or feel like you would have some sort of distinct advantage in. It just seems really hard to consistently make money.

If you look at most of the platforms, the teams that are large and growing tend to be biased to TMT, Consumer, and HC (in my experience) so I think they're probably the best place to start a career. Markets are always changing so who knows what the next 5 - 10 years will bring, but especially for TMT it's just such a broad sector that you can effectively "cover" any company you want while sticking to that high level mandate.
