As much as I think TSLA/SPCX are overvalued there is nothing unique about their drop compared to many other companies in the last day or two. I wouldn't even hazard a guess on whether the floor has fallen out on anything yet, it could just as well be a temporary reaction to the election results and volatility following the uncertainty of that for these types of companies.
Of course one can always pick a set of tickers and day ranges that make it seem like any trend if you filter the view enough.
