$Tesla(TSLA.US) The broader market has already started to sell off. I opened a short put on TSLA at 425 and made 20 points, the position wasn't large. As expected, it still couldn't break through and stabilize above 425. The next couple of days look a bit pessimistic. However, I still believe TSLA will rise for about half a day. The support level remains 413-415. I'll take a small call position at 413-415. If it breaks below and grinds with low volume, get out quickly. It's highly likely to trigger a broader sell-off. (Also watch the broader market trend; if the market strengthens, don't panic too much.)
