I have no doubt he has better returns than me lately. I don't do his style of swing trading anyway, so I am not following any of his trades closely and I used to follow his blog but not anymore. But set aside investments for a moment. The point about COVID is that he is still, to this day, on the side of the lunatic fringe saying that it is completely nothing AS A MEDICAL ISSUE. If he is so utterly wrong about something so basic, I find it hard to have much confidence in his judgement on anything else.
It seems like he could be a parallel to Larry Jeddeloh, who was the Director of Equity Research at Leuthold for quite a few years. Now, I haven't seen any of his work in the past decade, but he has run TIS Group for many years and it turns out he is a batshit crazy conspiracy theorist and in the years that I saw performance on his separate accounts, they were quite poor. I have to believe that Jeddeloh had some talent to have been a partner at Leuthold, but it seems the craziness overruled any genius he might have had. So Kuppy may well have a very good knack for some things, but at the same time he is inexplicably divorced from reality on some things. Could be a recipe for crash and burn.
