This is the first time I've walked through the full Slabnomics process from start to finish. Post-mortem to pattern recognition to filter to hunt to execution decision. End to end, with one real trade as the worked example.
I talk about:
Post-mortem methodology and tag-based pattern recognition
The four-tag rule for win-rate stacking
MLD framework applied to a current superstar's valuation
Supply structure analysis on Prizm World Cup Silver parallels
Alpha decay and the half-life of an information edge

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.

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.

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.

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
