But he avoids SpaceX and Tesla, which I think is probably the driving factor in not using QQQ. Maybe he values that more than $500
I'm unsure what SpaceX's weighting would be in QQQ but with Tesla being <3.54% weighting it would take both companies being 0s within a year to offset the cost in taxes from reweighting...
tombert should instead long QQQ and short the bits they don't like
If that was his genuine concern, then instead of trying to balance a portfolio of 103 stocks... you simply buy QQQ and short Tesla at 3.53% worth of your QQQ holdings.
