Tesla is a long-term bet, but a virtue of the stock market is that the market's horizon for payouts is potentially much longer than any individual's. If I'm holding a bunch of TSLA stock and want a payout in 2018, it doesn't matter to me what Tesla's profits are in 2018, it only matters how optimistic the market is about Tesla's long-term future- since that dictates how much I can sell my shares for in 2018. If Elon Musk shuts down sales altogether in 2018 but somehow convinces everyone that 2019 (or later) will be a complete blockbuster year, it still works out in my favor, since the market has superhuman patience I lack.
