>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
This has nothing to do with a 2018 payout.
Do you know what you are buying when you buy a share of TSLA? You are buying a claim to future profits. You expect to be paid in the future: when and how much? If you can't answer those questions, why are you buying stocks ?
