ASML had heavy bullish option activity reported on 11/18 with many PUT contracts hitting at or near the BID. One such contract was the $660 strike expiring TODAY (11/22/24). Now, there is the matter of these potentially being a hedge against a net-short equity position on the underlying; a theory that gains weight because of the trending growth in the short interest over the past three months. This means, however, that there may be a further unwinding of that net-short position to balance the delta which could bid up the stock today.
ASML We are at levels seen last November / December. If you're long already, just hold, this is still a valuable company. If your looking to purchase, there is risk at this price level, though in the long run it is still at a massive discount.
As bullish as I am, I would say that it would be more prudent to have a long entry around the $560 level than where we are today. I take nibbles every now and then, but the bulk of my order is at $560.
Options are a good way to hedge risk, and with IV averaging around 36% and December IV at that average, I would be buying PUTs over selling CALLs to hedge short-term risk. A vertical PUT spread buying ATM puts and selling OTM around $560 can help hedge at a reduced cost.
