Frequently Asked Questions
What is the Card Market Heat Map?
The Card Market Heat Map is a visual dashboard that shows the relative market temperature of every sports card segment. It cross-references sport (baseball, basketball, football, hockey) against era, value tier, or card type to create a color-coded grid. Hot segments (red) have high demand signals, cold segments (blue) have low activity. The temperature updates daily.
How is the temperature calculated?
Each segment temperature is based on four factors: card count in the segment (more cards = more collector interest), average card value (higher values = premium demand), rookie card percentage (more rookies = trending growth), and seasonal factors that shift daily. Temperatures range from -100 (coldest) to +100 (hottest).
What do the different views show?
Sport x Era shows market heat by sport and time period (Pre-War through Ultra-Modern). Sport x Value Tier shows which price ranges are hottest per sport. Era x Card Type compares rookie cards vs base cards across different time periods. Each view reveals different market dynamics — use them together for the full picture.
Should I buy cards in hot or cold segments?
It depends on your strategy. Flippers and dealers want hot segments where cards move quickly. Investors and value buyers often target cold segments where prices are depressed but fundamentals are strong. The heat map shows market sentiment, not intrinsic value — sometimes the best buys are in the coldest segments.
How often does the heat map update?
The heat map updates daily with fresh market temperature calculations. Seasonal factors shift each day, reflecting real-world events like the NFL Draft (football cards heat up), MLB Opening Day (baseball), NBA Playoffs (basketball), and NHL Stanley Cup (hockey). Long-term trends are visible when you check back regularly.
