Tesla shares rose more than 6% at one point, with unusual activity in the trading of $375 call options.

Tesla shares surged on Thursday, rising more than 6% at one point, becoming the focus of the US stock market that day. Tesla ultimately closed up about 5.4% at $376.37, reaching its highest level since mid-July.

While the spot market surged, the Tesla options market also saw significant fluctuations. Specifically, the trading volume of call options with a strike price of $375 significantly exceeded the number of open interest (OI) contracts at the time , indicating a large influx of new trades and increasing market bets on a short-term rise in Tesla's stock price.

This unusual activity also caught the attention of options traders. One trader posted his trading records on the social media platform X, stating that based on Unusual Whales' options fund flow data, he bought Tesla call options on Thursday and locked in a profit of approximately 50% after the stock price rose.

Tesla's recent surge is closely linked to its upcoming Cybercab event. The company will hold its self-driving Cybercab event in Austin, Texas on Thursday, with the market anticipating further details from Tesla regarding the commercialization of its autonomous taxis. Several media outlets have also previously pointed out that investors are viewing this event as a crucial juncture in assessing the scale-up prospects of Tesla's autonomous driving business.

It's worth noting that $375 was a crucial price level between the options trade and the spot price on that day . Tesla closed at $376.37, meaning the stock price had already surpassed the $375 strike price. The triggering of call options could further fuel the upward trend.

Amid a general upward trend in U.S. stocks, Tesla significantly outperformed the market that day. While the S&P 500 rose approximately 1% and the Nasdaq rose approximately 1.4%, Tesla's gains exceeded 5%.
