Why fundamentals, even for traders?
You don't have to be a value investor to need these. Fundamentals tell you what you're trading and why a move has a reason behind it. They matter most to the long-term owner — but a single earnings beat or catalyst can move any stock in seconds, and the broad market turns on macro data like the Fed and inflation. The more widely followed and liquid a market is, the faster information is priced in — so part of the skill is knowing how much weight fundamentals deserve in your game.
