I can understand low oil price causing an issue, but the terror attacks in Brussels not - NASDAQ is up overall, why hit TSLA?
In any case, the cheaper oil gets, the more that idiots burn it, the less there is for the future = finite resource...
Trailing stops protected my gains. Now to determine when the terror attacks stop the market downturn to purchase more shares at a discount. All trading is done in retirement account, so short term trades are not an issue.
