I'm pretty much in the same boat. At least in the short term, it's not so much the paper losses that matter as in how confident the paper losses are not symptomatic of a broader problem.
I think I've finally reached a strategy for today, regarding my view of being overexposed to TSLA. I'm going to sell some, but not at opening price, which I just consider unacceptably low for after a report like this. I'll have an order to sell in the ~$331 range, and then some low-probability "in case there's a big rise" orders at ~$345, ~$354, and ~$359. If we never hit ~$331... so be it. Tomorrow I'll reevaluate based on today's market performance and set some more "informed" sell targets which I'll maintain until they're either hit or clearly not going to be hit.
