The $TSLA drop at the beginning of the day was in lock-step with the -1.5% drop on NASDAQ, i.e. standard correlation. The high volume spikes looked like long position stop orders cascading.
Rest of the day so far was dip-buying with a fair amount of shorts covering as well I believe: $280 price levels are pretty good to cover at, for those shorts that shorted at around $300 levels sometime during the year and who have no intention to risk holding a short position across the Q3 deliveries and production letter which is only 3.5 weeks away, and the Q3 quarterly report which is 7.5 weeks away.
There was no significant TLSA-specific selling pressure that I've seen so far, price action was mainly macro driven.
I'd hate calling a bottom because the probability of getting the call right is so low statistically, but during most of the day buying pressure was at least equal to selling pressure, despite the very negative macro environment. Absent some negative event it's a pretty good discount if you are bullish about the rest Tesla's financial year.
