    Why You See "Buying, 80%" (And What to Do About It)

    Every Facebook card group has the post. Cash in hand. Buying at 80% of comp. Same wording, different accounts, every week. Nobody asks where the 80% came from. Today we do. This episode walks through the why of that number, the three cognitive biases that keep sellers accepting, and two practical things to do so we can stop seeing those posts. Why this practice preys on the very people we should safeguard for the long term good of The Hobby: New Entrants. Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

    The Discoverable Market: Why Cards Aren't Like Stocks

    Both sides studied the stock market. Nobody applied this to cards. Until now. In this episode of Slabnomics, we introduce the Discoverable Market framework and make the case that the card market is neither efficient nor random. It's exploitable. The information exists. Most people just aren't using it. ✅ What the Efficient Market Hypothesis actually means ✅ The 3 conditions required for market efficiency ✅ Why collector behavioral errors aren't random The card market is newly becoming a real market. The frameworks that explain its behavior are barely being applied. The information required to price these assets correctly is freely available — and widely ignored. That's the definition of a discoverable market. The question is whether you want to do the work. Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

    Negotiation and How to Get Leverage in Sports Cards

    Most card collectors think negotiation is just haggling: subtract from the sticker price, meet in the middle, done. It's not. In this episode, Matt breaks down the actual framework behind why deals happen and why they don't using Chris Voss's tactical empathy principles applied directly to the card market. You'll hear both sides of a real card show weekend: a buy that closed at his number and eight cards that didn't sell and why both outcomes were exactly right. Leverage is the only variable that matters. Your job is to understand whether you have it. Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram

    Diving into Liquidity: 3 Types and How To Exit the Pool

    This episode applies institutional liquidity frameworks to the card market. Three types of liquidity and what each one means for your portfolio. Why soccer trades like a two-buyer auction room despite 91% index gains. How price slippage destroys your comp stack when you hold multiples and list them sequentially. The difference between a market that is moving and a market that is coasting on inertia. And the exit framework that captures the middle of a move without the ego of trying to sell the peak. Topics: Sports card liquidity explained • Price slippage and comp arbitrage • Why thin markets move violently • Spotting trend exhaustion • Scale out exit strategy • Time stop discipline • World Cup sell window mechanics • Card Ladder price accuracy Weekly Newsletter Signup: Slabnomics.com 🎥Youtube 📸Instagram
