Pump and Dump
How operators inflate a thin stock with hype, then sell into retail demand.
Seven concepts. Pump-and-dump is a time story: quiet accumulate, loud hype, sharp dump. The animated price path is the teaching figure — tables name the phases; the plot shows the trap.

1Three phases
A classic pump-and-dump has three phases: accumulate (operators buy quietly), pump (tips and chatter lift the price), dump (operators sell into the rush).
Retail usually arrives in the pump and is left holding after the dump.
Figure. Price is walked up on thin float, then collapses when operators exit.
| Phase | What happens |
|---|---|
| Accumulate | Quiet buying in a thin name |
| Pump | Tips, screenshots, urgency |
| Dump | Operators sell; price collapses |
Retail investors most often get hurt in which phase pair?
- Buying in the pump and holding through the dump
- Only in the accumulate phase before any tip
- Never, because SEBI guarantees tip profits
Late tip buyers fund the dump.
2Why thin names are used
Illiquid, low free-float names move more on small orders. That makes a manufactured spike cheaper to create.
A liquid large-cap is a poor playground for the same trick.
Figure. Thin names: small volume can move price a lot.
| Trait | Why operators like it |
|---|---|
| Low float / illiquid | Small buys move price |
| Quiet history | Spike looks like a "breakout" |
| Tip-friendly | Story fills the vacuum |
Pump-and-dump schemes prefer
- Illiquid or low free-float names
- The most liquid Nifty heavyweights only
- Only government T-Bills
Thin float is easier to mark up.
3Tip flood is the fuel
The pump phase is social: WhatsApp forwards, "research" PDFs, and urgency. The story is the product.
If many strangers suddenly agree a forgotten stock is a multibagger, ask who needs your buy orders.
Figure. Operators accumulate, retail chases the tip, liquidity exits, late buyers are stranded.
| Signal | Read as |
|---|---|
| Sudden tip flood | Demand manufacturing |
| Urgency + secrecy | Pressure, not analysis |
| No document | Story without substance |
A sudden flood of tips on an illiquid name is best read as
- A demand-manufacturing warning
- Proof SEBI endorsed the tip
- A free lunch
Tip flood = fuel for the pump.
4Who wins and who loses
Early holders and operators who sell into strength win. Late tip buyers who provide exit liquidity lose.
Your fill during a euphoric tip is often someone else's exit.
| Actor | Typical outcome |
|---|---|
| Operator / early | Sells into strength |
| Late retail | Buys the top; holds the fall |
| Quiet peer stock | Often unchanged |
In a dump, late retail tip-followers mainly provide
- Exit liquidity for earlier holders
- Guaranteed profits from SEBI
- Free demat credits
You may be the exit.
5Volume and chatter together
Unusual volume plus a tip flood in a sleepy name is a stronger warning than either alone.
Price without volume can be noise; volume without a story is still worth suspicion in a thin stock.
Figure. Tip floods often arrive with unusual volume in an otherwise quiet name.
| Combo | Warning |
|---|---|
| Tip + volume spike | Classic pump tell |
| Price up, no volume | Weaker signal |
| After dump | Volume fades; bagholders remain |
The louder warning is usually
- Tip flood plus unusual volume in a thin name
- A single polite analyst note on a liquid giant
- An index rebalance announcement alone
Combine signals.
6Decision: do not chase
If you already missed the quiet accumulate, chasing the tip is volunteering for the dump.
Walk away. Capital preserved beats a screenshot of a spike you did not need.
Figure. By the time a tip reaches you the quiet accumulate is over, so the only role still open is exit liquidity. Refusing is not missing out - it is declining to pay for someone else's exit.
| Urge | Action |
|---|---|
| Chase the green candles | Refuse |
| Wait for "one more tip" | Refuse |
| Return to your plan | Yes |
You see a tip stock up 80% in a week on WhatsApp hype. Best decision?
- Do not chase; stick to your written plan
- Mortgage the emergency fund to max the tip
- Buy more because GMP-style chatter says so
No chase.
7If you were targeted
Keep records (messages, order IDs). Use official exchange/SEBI grievance paths — not recovery agents asking fees.
Reporting does not unwind a bad trade instantly; it is still the right hygiene.
Figure. Evidence first, then the official ladder: broker or exchange grievance, escalating to SEBI SCORES. Anyone who appears after the loss asking a fee to recover it is the second scam.
| Do | Don't |
|---|---|
| Official grievance + evidence | Pay a recovery stranger |
| Keep message/order records | Delete everything in panic |
| Learn the pattern | Double down on the next tip |
After a suspected pump-and-dump loss, avoid
- Paying a stranger an unlock/recovery fee
- Keeping contract notes
- Using official grievance channels
No recovery scams.
