Entry, invalidation, target: the three numbers a hunch doesn't have

August 12, 2026

"I think this card is going up" is not a plan. It's a feeling with a price attached. A plan has three numbers, and they only mean something together.

Entry zone

Not a single price — a range you're willing to buy into. A range acknowledges that you don't know the exact bottom, and forces you to decide in advance what you'd actually pay, instead of chasing whatever the market prints in the moment.

Invalidation

The level where your original reason for buying is proven wrong. This is the number most collectors skip, and it's the one that matters most.

Invalidation is not a stop-loss you adjust by feel as the price moves against you. It's decided before you're emotionally attached to the outcome — while you can still think clearly about what would actually prove the thesis wrong, not just what would hurt to see.

Target

The good outcome if the plan works. Note the phrasing: if it works. A target is not a promise the market owes you. A card can invalidate before ever getting close to it, and that's not a failure of the target — it's the plan doing its job.

Why all three, not just one

A target with no invalidation lets a losing position run indefinitely on hope. An invalidation with no entry zone means you never had a real decision, just a reaction to whatever price you happened to see. An entry zone with no target means you don't know what "working" would even look like.

Three numbers, decided together, before you act. That's the difference between a plan and a hunch wearing a plan's clothes.
