What Is Market Manipulation?

Market manipulation refers to illegal activities that are designed to distort the market's natural supply and demand. It involves an intentional act of creating false or misleading information to influence the price of securities, commodities, or other financial instruments.

Market manipulation can take many forms, including insider trading, spreading false rumors, or using complex trading strategies to artificially inflate or deflate prices. It is prohibited by various regulatory bodies, as it can have a detrimental effect on market integrity and investor confidence.

Types of Market Manipulation

Pump and Dump Schemes

Pump and dump schemes involve artificially inflating the price of a security through false or misleading information, then selling the security at its inflated price, causing the price to collapse and leaving other investors with significant losses.

Pump and dump schemes are particularly prevalent in the penny stock market and on social media platforms, where misinformation can spread rapidly. These schemes can cause significant financial losses for unsuspecting investors and erode trust in financial markets.


Spoofing involves placing fake orders in the market with no intention of executing them, to create a false impression of supply or demand, which influences other market participants and manipulates the price of the security.

Spoofing has been observed in various financial markets, including equities, futures, and cryptocurrencies. Spoofing distorts market information and can lead to inefficient pricing, causing financial losses for investors and undermining market integrity.

Wash Trading

Wash trading involves an individual or entity simultaneously buying and selling the same security, creating the illusion of increased trading volume, which can attract other investors and manipulate the price of the security.

Wash trading has been observed in stock markets, commodities markets, and cryptocurrency exchanges. This type of market manipulation can lead to artificial price movements, negatively impacting investors and undermining the credibility of financial markets.

Insider Trading

Insider trading involves individuals with access to non-public, material information about a company trading its securities based on that information, giving them an unfair advantage over other investors.

Prominent examples of insider trading include the cases involving Martha Stewart and Raj Rajaratnam. Insider trading erodes trust in financial markets, as it creates an uneven playing field for investors and can lead to significant financial losses for those not privy to the inside information.

Cornering the Market

Cornering the market involves accumulating a dominant position in a particular security, commodity, or other financial instrument, allowing the manipulator to control the price and supply of that instrument.

The Hunt brothers' attempt to corner the silver market in the late 1970s and early 1980s is a well-known example of this type of market manipulation.

Cornering the market can lead to significant price distortions, supply disruptions, and financial instability, ultimately harming investors and the broader economy.


Front-running involves using advance knowledge of pending orders or trades, typically gained through access to privileged information or technology, to trade ahead of those orders and profit from the price movement they cause.

Front-running can occur in various financial markets, including equities, futures, and foreign exchange.

Front-running undermines the fairness of financial markets, as it allows certain participants to profit at the expense of others and can lead to inefficient pricing and financial losses for other investors.
