This product's Amazon sales rank jumped 3× over its own pre-surge baseline. We called it a dud: the data said this spike would fade fast.

Faded — back near its old rank by day 21.

Amazon sales rank, inverted — higher = selling better. Dashed line = the day we made the call.

HOW THIS CALL IS GRADED

Every call is graded against the same fixed bar, set before the call is made: three weeks after the surge began, is the product still selling at at least 2× its pre-trend pace AND ranking among its category's proven sellers? Clears both = a keeper call was right. Fails either = a dud call was right. No judgment calls, no moved goalposts. This call applies the exact same live rules, day by day, to held-out history the model was never trained on (model trained through Feb 2026).

Scryup calls Amazon trends — keeper or dud — on day 3, from the data.

Every call is posted publicly and graded three weeks later, hits and misses both. See the whole board, or check any US product free — paste an ASIN and we'll email you the keeper-or-dud call.
