Just caught up on that crazy market day back in early March when everything started to sink hard. The whole market was getting hammered - S&P 500 down over 2%, Nasdaq down more than 2.3%, and crude oil just kept climbing past 8-month highs. That Iran situation was really spooking everyone, especially with talk about the Strait of Hormuz and threats to oil shipments.

What really got me was watching the domino effect play out. Energy prices were surging, which meant inflation concerns came roaring back, and suddenly bonds started selling off too. The 10-year yield jumped to 4.12%, which immediately put pressure on rate-sensitive stocks like homebuilders and airlines. Oil up that much means jet fuel costs spike, so the airline stocks were taking a beating. Meanwhile, the chip sector got absolutely destroyed - Micron down 8%, a bunch of other semiconductor names down 5-7%.

The tech megacaps weren't spared either. Tesla dropped over 4%, and Nvidia was sliding on top of export restriction concerns. But honestly, the whole market was in risk-off mode that day. Even with earnings season looking decent overall - like 73% of companies beating expectations - it didn't matter much when geopolitical risk and inflation fears are dominating the narrative. That's the kind of day where you just watch everything sink together.
