I agree though that due to what appears to be a bubble, these investments aren't that safe at the moment. It appears that these type of stocks have benefited recently by retail investors entering the market and piling in. ( https://thehill.com/policy/finance/510796-are-trading-apps-p... -- though, as the article points out, the Robinhood investor bubble is smaller than the effect of the Fed's QE etc. ) Under normal valuation, Tesla at this point I don't think would be considered "speculative" -- risky, but not as risky as some. But a P/E ratio of 1000+ even after this recent dip is IMHO pretty difficult to justify.
r/wallstreetbets is pretty unreal to me -- many people are focusing on high-risk options on these heavily valued stocks, and (by the comments) appear to be putting a lot of their "eggs" in only one or two "baskets", to use the popular phrase. It's not ending well for some of them, judging from some of the posts.
