Just for fun, I'm giving very serious thought to purchasing out of the money long dated puts on Tesla? Paired with long, dated at the money call options on Alibaba.

Alibaba at six times free cash flow seems outrageously cheap. Tesla at 80 times earnings or whatever the hell it is, seems outrageously overvalued for a capital intensive business with relentless competition and vapourware that appears to be utterly worthless.

There I've said it, I realise this is not in keeping with sound investing principles as advocated by Mr Buffett. However, I have rarely seen these kind of extremes and I have a strong sense that this market is going to take a dive over the next 2 to 3 years and Tesla may be the poster boy.

I realise this is speculation on my part, and I'm therefore only allocating a tiny fraction of my net worth to it. I just don't want to miss it.
