Why this product is stamped HOLD as of Jul 17, 2026.

  1. This weekBasically flat vs a week ago — the market is catching its breath.
  2. This monthUp 30.7% over the month — a real trend, not a blip.
  3. eBay supplyWe started counting live eBay listings recently — the month-over-month supply read unlocks as that history builds.
  4. Trend strengthOur core buy pattern: a powerful month-long climb that is still gaining this week. In our historical testing, established trends like this persisted far more often than they reversed.
  5. High convictionA premium product showing our highest-grade momentum pattern. Historically this is the most reliable signal we issue — serious-money products trend hardest in this market.
  6. Riding the highTrading near its all-time high with the broader trend intact. Confirmed in our own testing: in this market, strength at the top is fuel, not a ceiling.
  7. Steady premium climbA premium product grinding steadily higher without weekly drama. Our testing shows this quiet pattern pays at the top end of the market — and fails on cheap cards, so it only counts here.
  8. Room to runA strong trend on a card still trading well below its former peak — old ground left to reclaim. In our testing, momentum with headroom beat momentum at fresh record prices by a wide margin outside the premium bracket.
  9. Overheating checkThe price has gone near-vertical compared with its own recent average. Our testing found vertical climbs cool off more often than steady ones — so we withhold the buy stamp from cheaper cards in this state and treat premium ones with extra care.
  10. About dipsCounter-intuitive but tested: in this market, dips during uptrends usually keep dipping. A discount alone never makes us say buy.
  11. Rebound setupThe bargain-hunter pattern: a hard fall that has just turned upward, with price swings calming, on a set past its launch chaos. Speculative by nature — the winners historically paid well, but only about half the calls win.
  12. Why this stampNothing actionable either way. Most cards most days are exactly here — and patience costs nothing.
  13. New set cautionSets under about three months old swing wildly while boxes get cracked. Extra scepticism on brand-new sets.
