Meta-tagging 311 Sales: Lessons My Sports Card Portfolio Taught Me

from Slabnomics · host Matt

 I analyzed every trade I made over 10 months in one of my buckets:311 sales, $55,000 deployed and fed it all into Claude AI to find patterns. The result was a complete rebuild of how I think about sports card portfolio construction. Using meta-tags to track performance across player tier, set quality, rarity, and card type, I discovered that sets really do matter, and GOATs matter most in soccer. The finance brain wanted diversification across mid-cap players and international markets...the data said concentration in quality beats spreading thin. With the 2026 World Cup approaching, this analysis revealed exactly what to buy, when to sell, and why timing catalysts matters more than outcome gambling. Includes operational principles, meta-tagging methodology.
