Quote from Ghost of Cutten:
Ok I don't want to come off as using hindsight bias here, but this clearly wasn't a fraud, or bankrupt stock, there was no insanity, and it was arguably not all that overhyped either (at least, no more hype than any high growth company with blue skies potential). It's a potentially revolutionary product that could bank enormous long-run profits, just like Ebay or Amazon or whatever.
Also, 'might' is never a reason to put on a trade. 'Probably will' is minimum.
If there's one thing I've learned in shorting, it's never try a long-term short in a hot stock with a hot product where the news flow and momentum are positive. No matter how crazy the valuation, it is just too easy for either i) you to be wrong, and the business really IS growing that fast ii) you to be right, but the gogo crowd send it up another 100%+ on pure BS anyway iii) you to be right, but your put expires worthless because the move doesn't happen in time, or happens from a much higher price. Those kinds of stocks are only worth buying puts on when the momentum has *clearly ended*; and really, it is best to wait for momentum to go into a clear downtrend - this has to happen for all big declines anyway.
Also, hype alone is just not enough odds in your favour. The best shorts are things where EVERYTHING is in your favour - the business is deteriorating significantly, not improving; where the momentum is negative, not positive; where the flow of news is likely to have negative shock after negative shock, not the reverse; where the management is dishonest, clueless, or helpless, not where it's run by one of the best entrepreneurs in the world. At least try to get 75% of factors before taking the risk.
In fact, although the valuation argument is obviously more favourable now, and the momentum has cooled off, I would not even look at shorting TSLA now up at 160. The next $50 is a coin flip.
Stick to slam dunks, like some of the other good trades you posted on this thread. When you have a proven method, it's important to stick to it rigorously, and not pollute the results or trading process with marginal trades decided on a whim, or for emotional reasons such as thinking the price is 'too high'.
