My general philosophy is that big irrational drops are buying opportunities. Weeklies are too random for me (not to mention pricey this week), but I did pick up an Oct 16 when TSLA was at 247 and might pick up more if it continues dropping. I'm trying to be very cautious and remember the old trader's adage: the market can remain irrational longer than you can remain solvent (or, it can remain irrational past the expiration date of your options).
I don't think this drop is irrational at all. It has nothing to do with TSLA, it is a market correction of biotech overvaluation, primarily, and as a high-flying NASDAQ stock, we get correlated. If you are trading short term (like the title of this thread), I would be very careful. If you are buy and hold then obviously have room to run.
