I have noticed some angst, particularly over the past week, over the share price. I think that to avoid stress over investing in TSLA, it is best to follow this strategy: (1) Always have a "core" of (relatively) safe investments. These might be mutual fund holdings in a 401(k) or IRA that account holders can't access easily until retirement. I recommend broad market index funds. Sure, they are not 100% safe, and will go up and down with the whole market, but over time they generally go up. This is a backstop in case holdings in individual stocks go to pieces. Don't sell your core holdings, except to re-balance your asset allocation (stock/bond/cash percentages). Always contribute periodically to your core holdings. 401(k) contributions are the most common way to do this. The "core" will not make you rich quickly. It may never make you rich at all. It's there to ensure retirement security. (2) Use money that is less or not at all critical, for investment in individual stocks, like TSLA. This is money that can make you rich. But if it plummets to 0, the core will still be there for you. (3) Derivatives can cause a lot of stress. Know how you react to this level of risk and avoid derivatives if they freak you out. So hypothetically, suppose I have been working for awhile and I have, say for the ease of argument, 100k in my IRA (contains rollovers from old 401(k)s, some other contributions). Suppose, based on my age and projections, I need 75k in funds to grow to meet my retirement goals. Allocate 75k to the "core": 70k in stock index funds, 5k in bond index funds, or whatever is age appropriate. Allocate 25k to individual stocks. Divide additional contributions between "core" and non-core assets as time goes on. If you are fortunate enough to have $ for investment in taxable accounts, use the same strategy. Enjoy the gains from individual stocks. Sleep at night knowing that if you bet on a couple wrong companies, you won't be left with nothing. Just my 2cents, based on experience over the past few decades.
