What is a pump and dump scheme?
In one line: A pump and dump is a scam where people hype up a cheap stock or coin to push its price up, then sell their shares to the buyers they lured in.
What it means
A pump and dump is a scam in 2 steps:
- Pump. A group buys a cheap stock or coin. Then they hype it everywhere: posts, chats, emails, videos. New buyers rush in and the price jumps.
- Dump. The group sells into all that buying. The price crashes. The late buyers are left with the loss.
The hype was never about the business. It was about finding buyers.
Is it illegal?
Yes, in US stocks it's securities fraud. Pushing up a price with false or misleading claims, then selling, is market manipulation. The SEC brings cases against pump-and-dump schemes. Some crypto tokens count as securities and the same laws can apply. The SEC's investor site, Investor.gov, has alerts on this scam.
Where it shows up
- Penny stocks — very cheap shares, often traded over the counter, with little public information.
- Small coins and tokens with few holders.
- Shares with a tiny Share float, so a little buying moves the price a lot.
Warning signs
- Urgency. "Buy before it's too late!" "Next 10x by Friday!"
- Unsolicited tips. A stranger messages you about a stock or coin.
- A sudden price and volume spike with no real news.
- Promises of huge, fast gains. Real businesses don't come with guaranteed returns.
- Paid promoters. Look for small print saying someone was paid to promote it.
- Little or no real information about the company or the team.
If someone needs you to buy right now, ask why they're in such a hurry to find buyers.
A simple example
A $0.20 stock nobody talks about suddenly fills group chats. "This one's going to $2!" Volume jumps 50 times its normal level. The price hits $0.60 in two days.
Then it falls back to $0.15 in an afternoon. The promoters sold near the top. Many late buyers become Bag holders. This is a described example of the pattern, not a real ticker.
How to protect yourself
- Never buy on a tip from a stranger or a chat group.
- Check filings on sec.gov for US companies.
- Keep every trade small and with a stop. See how much to risk per trade.
- If you suspect fraud, you can report it to the SEC through sec.gov.
