Man, what a bloodbath in the stock market today. The major indices got hit hard - S&P 500 down over 1%, Nasdaq dropped 1.13%, and the Dow absolutely tanked 1.66%. That 822-point slide in the Dow was brutal.

The whole thing started with Trump's tariff announcement over the weekend. He bumped those "global" tariffs from 10% up to 15%, and Wall Street did not like that at all. You could see it playing out in real time - multinationals and financial stocks got hammered. IBM, American Express, Visa, JPMorgan Chase all bleeding. Even the big names weren't safe.

What's interesting is how the tech sector split. Nvidia actually managed to stay slightly green, up almost 1%, but software stocks and cybersecurity got crushed. Salesforce was one of the worst performers today. The whole AI narrative is getting mixed signals - people are worried about disruption (especially after Anthropic's new tools spooked the market), but also waiting to see if the AI infrastructure spending actually pays off.

Honestly, everyone's watching Nvidia's earnings report coming Wednesday. If they deliver solid numbers with strong guidance, that could flip the mood back to bullish. If they disappoint, the Nasdaq could sink further. Expect volatility for the next couple trading sessions - this tariff uncertainty combined with earnings season is creating a lot of moving parts.
