What is a Pump-and-Dump Scheme?

Pump and dump in stock market scam is a situation where people inflate the value of the stock by creating good rumours about the stock or overpromising growth. When retail buyers invest in such stocks, the perpetrators sell off their stock at the overvalued price, which then causes the collapse of that stock.

Steps involved in pump and dump in stock market scheme are:

1. Cumulating stock in low prices. 

2. Concocting artificial publicity on the stock through social networking sites or other messaging apps.

3. Sudden rise in the volume and prices of the stocks. 

4. Selling off of the stock by the perpetrators. 

5. Dramatic fall in prices.

SEBI categorizes it as market manipulation under PFUTP (Prohibition of Fraudulent and Unfair Trade Practice) regulations.

Why Pump-and-Dump Schemes Are Increasing

Several factors have contributed to the rise of pump and dump in stock market activities:

• Growth of social media investment groups. 

• Increased participation in small-cap and SME stocks. 

• Availability of anonymous messaging platforms. 

• Lack of financial literacy among new investors. 

• Rapid spread of unverified stock recommendations. 

Recent investigations revealed that manipulators used Telegram channels, WhatsApp groups, X (formerly Twitter), and other social media platforms to promote low-liquidity stocks and attract retail participation. 

Scale of the Problem in India

Based on government statistics, from FY 2020-21 to FY 2024-25:

These statistics indicate the strict enforcement policy adopted by the regulator against practice of the pump and dump in stock markets.

Another prominent case occurred in the year 2026, wherein SEBI detected a social media-based manipulation scheme in 82 stocks worth about Rs.20.25 crore.

How SEBI Detects Pump-and-Dump Activities

 1. Real-time Market Surveillance System

Some of the surveillance systems include those that monitor:

• Unusual price movement 

• Sudden increase in volume 

• Concentration of buying 

• Circular transactions 

• Unusual order activity 

In case a particular share has shown signs of unexplained price appreciation and increased trading volume, then it raises alarms.

2. Algorithmic and AI-based Surveillance

Data analysis and predictive surveillance techniques have been widely used by SEBI to spot cases of pump and dump in stock market scams before they become problematic for the investors. 

The enhanced monitoring system employed by SEBI is capable of:

• Detecting past manipulative trends.

• Comparing current activities with those seen in past scams.

• Tracing coordination between various accounts.

• Picking up any strange relationship between prices and volumes.

This move towards proactive surveillance is indeed revolutionary in market regulation. 

3. Social Media Surveillance

Most of the modern instances of operations of pump and dump in stock market happen via social media.

The SEBI surveillance includes: 

• Telegram channels

• WhatsApp groups

• YouTube investment videos

• X posts

• Stock investment forums

4. Pattern of Trade

SEBI analyses trade pattern to detect:

Circular Trading

Accounts buying and selling the securities amongst each other repeatedly to generate volume artificially.

Synchronized Trading

Several accounts placing their orders at once to impact prices.

Layering and Spoofing

Placing and subsequently cancelling large orders to falsely signal strong buying or selling interest in a stock.

Front Running

Individuals purchase securities prior to recommending to investors.

All of these may be considered as pointers to a bigger scam of pump and dump in stock market operations. 

5. Enhanced Surveillance Measures (ESM)

SEBI and stock exchanges subject certain stocks to Enhanced Surveillance Measures from time to time.

Criteria for selecting stocks for ESM include:

• High price volatility 

• High volume activity 

• Weaker fundamentals 

• Low market cap 

• High speculative trading activity 

ESM could involve:

• Further margins 

• Trade-by-trade settlement 

• Daily price review 

• Brokerage limits 

Such measures curtail the manipulators' ability to raise prices artificially.

6. Additional Surveillance Measures (ASM)

ASM is another risk management tool which aims to limit speculation.

Shares that fall under ASM have the following features:

• Increased margin requirement 

• Low leverage options 

• Strict regulation 

This is to prevent any excess speculation linked with pump and dump in stock market scheme.
