I agree and I'm looking forward to watching this play out but my real eye is on the long-term growth of the company. Because as the company goes, so will the share price. What we have witnessed today is the beginning of the market adjusting to Tesla's actual prospects. It's still under-valued. Play the volatility at your own risk.
I agree with this and want to pile on.
I first bought shares in TSLA back in late 2012 when the stock price was bouncing around in the 20's and 30's. I'd test driven the Model S and somehow my brain put together the idea that the product mattered, and a product that altered your life was going to do well.
So I bought some shares with a 10+ year horizon based pretty much exclusively on Model S (and later X - the car I actually wanted).
Good thing I had that 10+ year horizon - in 2013 there was a surprise profitable quarter and the stock went from the 30's to the 180's over 6 months I think it was. I was never tempted to sell along the way, but I remember many people in the investor thread that sold / locked in their gains in the 40's, 60's, 90's. Many of them expecting the stock to trade back down where they'd get back in. And then later, after missing 10's of $ in gain, buying back in anyway (or never buying back in and missing a 5-10x move).
If you're trading the stock, then this doesn't mean anything to you. If you've got a 3 year time horizon, or you've got money that needs a particular outcome in a few months or years, this idea isn't meaningful (so ignore everything I'm writing).
If you're a long term owner of the company, then by definition you shouldn't be trading in and out. The risk is too high that a day like today will happen and you'll sell at $250 going into earnings, expecting to buy back at $220 tomorrow. Then wake up with the stock at $300 and miss that move.
Of course, the stock can still trade back down to $220 (the stock market is a casino in the short term, and can easily be irrational longer than any of us can stay solvent), but it also might never go back. With a 10+ year time horizon and a reasonable (to me) investment thesis for a $6000 share price, selling for anything under $2000 in the very short term is leaving a lot of money on the table. (NOTE - that's my investment thesis, and useful to my situation).
Which also means, and this is equally important - I no more made $50/share today on the earnings call, than I lost $150 on some of my shares on the way down earlier this year. I still own all of them, in both cases, and I'm still looking at a company I think worth $6000 sometime in the next 5-15 years, and that I think there's a reasonable chance I'll own until I'm dead (much more than 10 years).
Another interesting thought that's gone through my brain. I've been waiting for the market to have a collective oh heck moment, when it suddenly realizes TSLA is incorrectly valued (as happened back in 2013). Then it was a run from 30 to 180 (ish). I consider it at least possible that we're at the front end of a similar revaluation of the company - a run from here to $1500-2500 over the next 6 months doesn't strike me as silly.
At some point, the stock price will become disconnected from the last several years of trading history, and it'll float off to go find a new trading range. I don't know where that'll be - only that if I'm right, then the last several years of trading history will become irrelevant until a new trading range / valuation is found.
(No trading advice here for anybody's particular situation - just an idea to think about - be clear about your own investment thesis and what you're looking to accomplish, and don't work at cross purposes to your own outcome).
