Market took a hit today across the board. S&P 500 dropped 0.58% to 6,829.91, Nasdaq slipped 0.26%, and the Dow fell harder at 1.61% to close near 47,954. The main culprit? Oil prices absolutely surged 9% amid ongoing Iran tensions, which also pushed natural gas futures up 4%. Shipping through the Strait of Hormuz basically ground to a halt, so investors are getting nervous about inflation creeping back into the picture.

The semiconductor names took it on the chin today after reports surfaced about potential new AI chip export restrictions. Nvidia, Lam Research, and Applied Materials all retreated as traders worried about licensing requirements for overseas sales. Pretty much the whole stock market today was feeling that pressure.

One bright spot though - The Trade Desk absolutely popped off, jumping around 18% after some positive media coverage. The company apparently started early talks with OpenAI about helping them roll out ads on their platform. Even better, the CEO Jeff Green disclosed he'd been buying shares on the open market - his first time doing that in years. After the stock had tanked 79% from its peak, that kind of insider buying definitely caught people's attention. Signals like that can matter when everyone's reassessing risk in today's market environment.
