Hobby Heat Index is radar for trading cards. Every morning we sweep 38,000+ athletes across every major sport and flag who's heating up — before their cards move. The heat score (1–100) shows signal strength right now. Here's what the signals mean: BUY NOW = undervalued, price likely rising  ·  SELL NOW = peak hype, best window to cash out  ·  HOLD IT = stable, sit tight  ·  WATCH = blip on the radar — something's developing, keep an eye on it. A 90 heat + SELL means the athlete is at peak buzz — ideal time to sell at top dollar before the market cools.
