Not another stock picker
Seeking Alpha and Motley Fool tell you if a stock is a good pick. We tell you if it's real, before you decide anything else.
Every result shows the exact signals we checked, not a score you have to trust blindly. See how it works →
“It felt rude to double-check. I did it anyway.”
How it works
A quiet second opinion, before the money moves.
ScamDunk isn't a broker, a newsletter, or an algorithm telling you what to buy. It's the 15-second check most people wish they'd done.
You get a tip.
From a friend, a group chat, a message you weren't expecting. It sounds convincing.
We check the fingerprints.
Filings, promoter history, message patterns, price behavior, the exact signals fraud investigators look at.
You get a plain answer.
In 15 seconds, with the receipts. Every flag comes with what we found and where.

ScamDunk is a free stock scam and fraud checker for self-directed investors. Enter a US stock ticker (NYSE, NASDAQ, AMEX, or OTC) or paste a suspicious stock tip, and ScamDunk analyzes it for pump-and-dump patterns, unusual volume and price behavior, promoter history, SEC alert-list hits, and manipulation red flags — then returns a plain-language risk verdict with the exact signals found, in about 15 seconds. ScamDunk is not a stock picker, broker, or newsletter and gives no investment advice; it checks whether a tip is real before you decide anything else. 6,900+ US stocks are scanned automatically every trading day.
