What Is a “Pump and Dump” Scheme?

A pump and dump is a form of market manipulation. Someone (or a group) artificially inflates a stock’s price by spreading false hype, then sells their shares at the inflated price, leaving other investors with worthless stock.

It happens in three stages:

Stage 1: The Setup (Buy Cheap)

The scammers target small, thinly traded stocks — companies most people haven’t heard of, often trading for just pennies. Because these stocks are so small, even a modest amount of buying can push the price up dramatically.

The scammers quietly buy a large number of shares before anyone notices.

Stage 2: The Pump (Create Hype)

Now they need other people to buy the stock and drive the price up. They use various tricks :

  • Social media and chat groups: They create WhatsApp, Telegram, or Discord groups that look like exclusive “investment clubs.” They post fake tips claiming the stock is about to explode .
  • Fake endorsements: They might use AI-generated videos or fake accounts pretending to be famous investors or financial experts .
  • Urgency and FOMO: They pressure people to buy now before it’s “too late.” This fear of missing out is a powerful tool .
  • Fake news: They spread false or exaggerated claims about the company — a “breakthrough product,” a “major contract,” etc. .
  • As more people buy, the price rises. This attracts even more buyers who see the price going up and think they’re onto something big.

Stage 3: The Dump (Sell and Run)

Once the price is high enough, the scammers sell all their shares at the inflated price. This is the “dump.” The sudden selling causes the price to crash. Everyone else who bought in is left holding shares that are now worth a fraction of what they paid.

A Simple Example

Imagine a tiny company called “ABC Penny Corp” trading at ₹10 per share.

  1. Setup: A scammer quietly buys 100,000 shares at ₹10 each. Total cost: ₹10,00,000.
  2. Pump: The scammer creates a WhatsApp group called “Elite Stock Tips.” They post: “ABC Penny Corp is about to announce a revolutionary new product! Price will hit ₹100 soon! Buy now!” Dozens of people in the group (some are the scammer’s accomplices posing as excited investors) start buying. The price rises to ₹50.
  3. Dump: The scammer sells all 100,000 shares at ₹50 each. Total received: ₹50,00,000. Profit: ₹40,00,000.

The scammer exits. The hype stops. The price crashes back to ₹10 or lower. Everyone who bought at ₹50 loses most of their money.

Real-World Scale

This isn’t a small-time scam. Regulators worldwide have taken action:

  • In India, SEBI banned 222 entities in a ₹144-crore pump-and-dump operation across five stocks. The scheme used fake SMS messages designed to look like they came from reputable brokers.
  • In South Korea, a $500 million scheme used complex instruments called CFDs to hide activity and leverage the manipulation.
  • In Australia, four people were sentenced to prison for using Telegram group chats to pump up penny stocks.

Warning Signs to Watch For

  • Unsolicited tips from strangers on WhatsApp, Telegram, or social media .
  • Pressure to act fast — “buy now or miss out” .
  • Promises of guaranteed or huge returns .
  • A sudden price spike in a stock no one has heard of .
  • Fake celebrity endorsements — scammers impersonate trusted figures .

If it sounds too good to be true, it almost certainly is. Always do your own research and never invest based on a tip from someone you don’t know.

what is pre market in share market in India

The pre-market refers to the period before the official opening of the stock exchange (9:15 AM IST) when investors can place buy and sell orders for stocks. However, these orders are not executed immediately; they are collected in an electronic queue and are matched when the market opens.

Key Details of the Pre-Market Session in India

1. Timing

The pre-market session in India is divided into three parts:

  • Opening Session (8:45 AM – 9:00 AM):
    • Orders can be placed, modified, and cancelled.
    • No trades are executed in this period.
  • Pre-Open Order Matching Session (9:00 AM – 9:08 AM):
    • This is the most critical 8 minutes.
    • Orders placed earlier are matched and executed to determine the Opening Price for the day.
    • During this time, you cannot place new orders, modify, or cancel existing ones.
  • Buffer Period (9:08 AM – 9:15 AM):
    • A transition period to prepare for the normal market open at 9:15 AM.
    • No orders are matched or executed.

2. The Goal: Determining the Opening Price

The primary purpose of the pre-market session is to find a fair equilibrium price for a stock at the start of the day. This price is calculated based on all the buy and sell orders accumulated during the pre-market period.

This helps avoid wild and volatile swings the moment the market opens.

3. Who Can Participate?

  • All investors with a trading account—retail investors, institutions, etc.—can place orders.
  • The orders are placed through your regular trading platform (provided by your broker), just like during normal market hours.

4. Types of Orders Allowed

Generally, only Limit Orders are allowed in the pre-market session. This means you must specify the maximum price you are willing to pay (for a buy) or the minimum price you are willing to accept (for a sell). Market orders are typically not allowed.

Why is the Pre-Market Session Important?


It acts as an early indicator of market sentiment for the day. By observing the pre-market activity, you can gauge:

  1. Gap-Ups and Gap-Downs:
    • Gap-Up: If the matched opening price is significantly higher than the previous day’s closing price. This indicates bullish sentiment.
    • Gap-Down: If the matched opening price is significantly lower than the previous day’s closing price. This indicates bearish sentiment.
  2. Reaction to News and Events: The pre-market session reflects the market’s immediate reaction to:
    • Company-specific news (e.g., quarterly results, a new CEO appointment, a major deal).
    • Global events (e.g., US market performance overnight, movement in Asian markets).
    • Macroeconomic data (e.g., GDP numbers, inflation data released before market hours).
