@Jeff Miller: very fair points, and the reason why most of my money is in mutual funds. With Tesla, though, I don't think the efficient markets hypothesis holds up--there are too many people using TSLA as a proxy for a personal POV about any number of factors, including (a) whether small public car companies can succeed, (b) whether the public is ready for EVs, (c) whether public policy will blow for or against EVs, and (d) whether Tesla management will stumble.
I think it's informative how few analysts have every touched a Model S, let alone driven one. More importantly, few of them have talked personally to anyone on the Tesla management team. There is, therefore, a large gap between the information (and credibility of the information) that those of us who follow TMC obsessively have and that which the typical institutional or retail investor has. This gap creates an opportunity for trading advantage that doesn't violate normal financial theory.
Summary: as I told my financial guy, "No one's ever lost money betting on Elon Musk."
Yeah, almost all my money is in low cost Vanguard index funds. I didn't start out investing this way, but that's where I have ended up.
I think there can, occasionally, be some inefficiencies in the market when it comes to small companies that are not heavily followed, so there
may be some excess return
from investing in one of them that you have studied and know particularly well. But given the high transaction costs associated with options, given the substantial
tax disadvantages of short term capital gains (top marginal rates of around 50% these days in most states, when you add up the federal, state and health care taxes),
and given that with options, you must also know not only "what" but "when", I'm somewhat doubtful that active trading is the way to go. If I were taking a bet on
Tesla (other than buying their cars), I'd buy the stock and then try to forget about it. The idea that it's possible to actively trade in and out with a profit (aside from one gained by chance) without having any special knowledge I find extremely implausible. It would mean that you have the ability to forecast the price of the stock and to value options
on short time scales (say months), better than the market - a skill that I don't believe exists. Even if you are a company insider and know everything that can be known about the company, there are many factors that are essentially unknowable - such as aggregate opinions on the topics on your above, not to mention
overall market movements - which will strongly affect the price of the stock and its options.
