Right, if the SP is driven up very quickly due to shorts covering, then it can be expected to come down again quickly.
But what worries me is that during this short time, the SP will run through the order books at an insane rate, so the bid-ask spread can become huge, so some tier-N retail traders like myself will be far from getting timely updates to the bid-ask - so there is a risk that one's limit order will be filled right at or very close to the limit, although at that moment the bid-ask may look very different.
Think about it, if the SP goes up (or down) at say 100$ every minute (and 10 times that for options), the average retail trader will likely enter a far from optimal trading order - and some market makers may have someone on their desk who tries to (illegally) profit from that, on the thinking that with the extreme volatility and volume overload no one will notice.
So while it is an interesting thought that we momentarily reach ArkInvest's 4k $ SP some time this spring, that moment could also be a moment were the ill-informed and ill-equipped retail seller who tries to take some profit gets completely screwed over.
So a recurring pattern of a 1-2% daily gain for a few days followed by some minor correction actually seems better, to me at least.
