So the market closed just under $320 then in after hours it went to $320 exactly.The stock market has just entered the Triple Witching Hour prior to a quarterly expiration of stock index futures and options and individual stock options. That combined with end-of-year portfolio rebalancing by institutions and tax loss selling by individuals prior to a low volume holiday week, could make this hour quite interesting.
Open interest in TSLA December 21st $320 puts is huge. Interest in the related calls is relatively modest. I suspect it likely that market makers and hedge funds would want to support a close of at least $320 to shut out put owners. In fact the situation is similar at the $330 strike price. If they have the muscle, the deep pocket writers of those puts may want to try to push the share price above that level too.
Is the settlement price at the bell?
Based on my post count I may never post again!
