Caught the market action from early February and it was pretty interesting how things shook out. The stock market was doing that classic rotation thing where money moves between sectors. Tech stocks took it on the chin that day - the Nasdaq dropped 1.5% with those AI chip names getting hammered, but the Dow actually went up 0.5%. Classic divergence. The S&P 500 fell 0.5%, so basically a mixed day across the board. What stood out to me was the sector split. Energy, materials, and consumer staples were the winners that day, up between 1.5% to 3.2%. But tech, comms, and healthcare all tumbled, with the tech sector down 2.2%. You could really see where investors were rotating their money. Volume was pretty heavy too at 24.6 billion shares, above the 20-day average. The VIX ticked up 3.6% to 18.64, so people were getting a bit more nervous. On the individual stock side, AMD reported solid earnings but the stock market didn't care - it crashed 17.3% because apparently the expectations were even higher. Amgen had a better day though, jumping 8.2% on decent results. Private payrolls came in weak at 22k new jobs in January, which probably added to the caution. This was one of those days that reminds you the stock market doesn't always reward good earnings if sentiment shifts. Interesting to watch how it all played out.
