A number of top-tier high-frequency trading firms have started expanding into the mid-frequency space. These firms already have excellent infra and have invested heavily in ML talent, which makes me wonder whether traditional stat-arb firms will increasingly get squeezed out by these highly sophisticated competitors. Do you think this is actually happening? Have people in the industry seen meaningful alpha decay in mid-frequency strategies as a result?

I have known some people from grad school that are also in the industry but we were not super close and usually do not hang out.

Otherwise, I just live my day to day and mostly socialize with people in my own company. How do you get to know more people?
