TSLA is at a great spot to scoop shares for the long term. Factor in the volatility to size the trade. You could spend 2% of your account on it, perhaps a bit more but not more than 5%. For swing trading, your risk is 15 dollars per share here. This level has held almost all declines so far, and price's turning up from here. The massive short interest makes for decent income while you hold positions as well, if your broker pays you part of what it charges to short sellers.
