What is spoofing in the stock market?

In the order book, you can see how many people want to buy or sell at each price. Spoofing is a trick that misuses this. This page explains what spoofing is, how it works, a famous case and how regulators deal with it.

Quick answer

It is a form of market manipulation where a trader places large buy or sell orders with no intention of letting them execute. The orders create a false picture of demand or supply. Other traders react by moving the price. The spoofer then trades on the other side at a better price and cancels the fake orders. It is illegal in India and many other countries.

Key takeaways

• It uses fake orders to mislead other traders.
• The orders are cancelled before they can be filled.
• It is a type of market manipulation and is illegal.
• Layering is a related method using many fake orders.
• Exchanges and SEBI monitor order and cancellation patterns.

What is spoofing?

Traders watch the order book to judge buying and selling pressure. A spoofer takes advantage of this. They place a large order they do not plan to complete, just to make the market think there is strong interest at that price.

Once other traders react and the price moves, the spoofer trades in the opposite direction, then quickly cancels the large order. The aim is to profit from the price move their fake order caused.

A simple example

A trader wants to sell 1,000 shares at a higher price. They place a fake buy order for 1,00,000 shares just below the market price. Other traders see this large buy interest and start buying, which pushes the price up.

The trader sells their 1,000 shares at the higher price and then cancels the large buy order before it fills. The market was misled by an order that was never meant to be real.

A famous case

A London-based trader, Navinder Singh Sarao, was charged in the US for spoofing in index futures and was linked by authorities to the 'flash crash' of 6 May 2010, when US markets fell very sharply within minutes. He pleaded guilty in 2016. In the US, the Dodd-Frank Act of 2010 explicitly banned spoofing.

The case showed how such fake orders, especially when placed by automated systems, can affect prices across a whole market for a short time.

How is spoofing treated in India?

In India, the SEBI (Prohibition of Fraudulent and Unfair Trade Practices relating to Securities Market) Regulations, 2003, known as the PFUTP Regulations, prohibit manipulative and deceptive practices. Placing orders to create a false appearance of trading falls within these rules.

Exchanges run surveillance systems that watch for unusual order and cancellation patterns. SEBI can impose penalties, ban people from the market and order them to give up unlawful gains. Ordinary investors should remember that large orders in the order book are not always real.
