📈 Buy / Hold / Sell Outlook

Every card's own 90-day move set against its set's move, graded by what the same setup did next in seven years of real sales (2019 on, 90 monthly checkpoints). This is a measured tendency, not a promise: the odds and the typical move are printed on every row.

How we know

Two years of real sales, nothing else. At the start of every month from January 2025 to June 2026 we looked at each card's last three months of sales against the nine months before (the card's own move) and the same thing across its set (the set's move), then watched what the card actually sold for over the next three months. That gave 22,637 card-quarters with a real follow-up sale. Two things held in both years: a card's own three-month move tends to reverse, and a set's move tends to keep going. The table below is the whole rule; every card carries its row's numbers.

Base rate over the same period: a median +5.3% with 55% of cards rising. "Flat" means within ±10% for the card and within ±3% for the set. A card with no sale in the last 90 days has no own read and shows HOLD.
