he exercised call options. I havent seen disclosed what he paid for them. The stock is at 160. Exercise price was 150
He could have just sold the call options. Maybe he wanted the stock so he could write calls or puts on it.
He could have just rolled over the calls if he was expecting a big price jump
He could very easily be down on those calls. NVDA is a GREAT stock and they have lots of stuff going relative to AI and other advanced applications. That said, NVDA is down along with most other NASDAQ stocks, and could be A LOT (40-50 points) down. But if the calls were short term, he may have exercised them anyway so as not to lose his entire investment.
