I used to when I started, but I don't anymore. Now I just buy stocks of companies I like. Lately for instance, I bought some NVDIA shares because I like what they do. Also last year I realized I didn't own any AMZN share and I thought that was not right, without even considering the fact that they don't pay any dividend at all. Same for Netflix or Cray or Tesla.
In truth, my mindset is more of a collector than an investor :P
