Yeah…just a side note: Those are VERY unusual gains, that won’t be common. But I’m thrilled he got them. The massive surge/rebound that came helped to be a tailwind on those.
But that’s how systems work. You’ll have some “knock it out of the parks” and some sub-pars and many very solid gains and some losers. And when you mix it all together over time, you’ve got a respectable overall return.
