Far too early to call. As
@generalenthu mentioned, market makers were able to dump millions of shares yesterday after delta hedging requirements were lowered due to profit taking (and I think also lower IVs).
Furthermore, the amount that index funds will have to buy is enormous. Even if benchmarked funds are mostly positioned already (but they could not be), those 26M shares that will have to be bought by index funds is no small numbers.
And last but not least, don't forget we're talking about TSLA here. Once buying starts, and SP starts to run up, not only will delta hedging mechanisms add fuel to the fire, so will shorts covering, traders, retail FOMO, etc.
I'm not saying there will 100% be a crazy run up next week nor later when S&P inclusion happens, but it's also far too early to say this will not happen. All the things that we've theorized could cause a crazy squeeze are still there. 1-2 red days post ER changes nothing about that. After Q4'19 ER, stock price got pinned to $650 too on Thu and Fri, to be followed by 2 of the craziest days of trading I've ever seen on Feb 4th and Feb 5th.
