How Market Operators Control Stock Prices

The stock market, a platform where buyers and sellers engage in trading financial instruments, is often seen as a level playing field. Yet, some sophisticated market operators manipulate stock prices to gain unfair advantages. Such tactics harm regular investors and undermine market integrity.

Market manipulation is illegal in most countries, but perpetrators use various methods to achieve their goals, making it difficult for regulators to curb these practices.

In this article, we will explore six prominent tactics used by market operators to manipulate stock prices.

1. Pump and Dump

Pump and dump is a classic stock manipulation scheme in which perpetrators artificially inflate the price of a stock to sell it at a higher price, leaving unsuspecting investors with losses. In this scheme, manipulators—often referred to as “pumpers”—buy large quantities of shares in a company, typically one with low liquidity and a market capitalization of less than ₹100 crores. These stocks, often referred to as penny stocks, are easier to manipulate because their prices can be swayed by relatively small volumes of trading.

Once the manipulators have acquired a substantial position, they create hype around the stock, disseminating exaggerated or false information through social media platforms, online forums, emails, or even SMS messages.

These promotions suggest that the stock is set to skyrocket, enticing inexperienced investors to buy in. As more investors jump in, the stock price rises, allowing the original perpetrators to sell their shares at a profit. After the dumpers sell off their stock, the price crashes, leaving the remaining investors with significant losses.

Pump and dump schemes are particularly effective in markets with minimal regulation or oversight, where small stocks often escape the attention of regulatory bodies.

2. Short Selling and Spreading False Information

Short selling is the reverse of pump and dump, and it involves betting that the price of a stock will fall. Market operators who engage in this tactic take a short position in a stock, borrowing shares to sell them at the current price with the hope of repurchasing them at a lower price once the stock drops. However, some manipulators take this a step further by deliberately spreading negative news or rumors about the company to push its stock price down.

These bad actors may use false information or exaggerated claims about a company’s financial troubles, regulatory challenges, or potential business failures. Once the stock price falls, they buy back the shares at the reduced price, return the borrowed shares, and pocket the difference as profit. The deliberate spreading of misinformation, also known as a “bear raid,” causes panic selling, leaving regular investors vulnerable to significant losses.

3. Wash Trading

Wash trading is another deceptive tactic used to manipulate stock prices and trading volume. In this method, an operator simultaneously buys and sells the same security, often through different accounts, creating the illusion of significant trading activity. The goal is to artificially boost the stock’s volume and price to attract other investors.

Once other investors, misled by the perceived trading activity, buy into the stock, the manipulator can sell at a higher price, profiting from the falsely inflated value. Wash trading deceives retail investors by making a stock appear more active and desirable than it truly is, leading to misguided investment decisions.

Wash trading is illegal in most jurisdictions, but perpetrators often operate through complex networks of accounts, making it difficult for regulators to track down and stop.

4. Spoofing

Spoofing is another form of market manipulation where an operator places large buy or sell orders with no intention of executing them. The aim is to create the illusion of strong demand or supply for a stock, tricking other investors into reacting.

For example, a spoofer might place a large buy order for a stock, signaling to the market that there is significant demand. This can push the price up as retail investors rush to buy in. Once the stock price rises, the spoofer cancels their buy order and sells their previously acquired shares at the higher price.

Conversely, spoofing can be used to push stock prices down by placing large sell orders, causing panic selling among retail investors. The spoofer cancels the sell order once the price drops and buys shares at the reduced price, making a profit when the stock’s price stabilizes. Spoofing, while illegal, is difficult to detect because orders can be placed and canceled within milliseconds in high-frequency trading environments.

5. Front-Running

Front-running is an illegal practice where someone with advance knowledge of a large trade order, often an insider or a broker, uses that information to trade the stock for personal gain. For example, if a broker knows that a major institutional investor is about to buy a large number of shares, they might purchase the stock before the order is executed, expecting the price to rise once the large buy order is placed.

This manipulative tactic allows the front-runner to sell their shares at a higher price, profiting from the large investor’s trade. However, it harms regular investors by driving up the price before they have a chance to buy, leaving them to pay inflated prices. Front-running undermines market fairness and can erode trust in the financial system.

6. Insider Trading

Insider trading occurs when someone with access to non-public, material information about a company uses that information to buy or sell its stock for profit. For instance, an executive who knows that their company is about to release exceptionally positive earnings results may buy shares in advance of the announcement, benefiting from the subsequent stock price surge.

Insider trading is illegal because it gives individuals with privileged information an unfair advantage over the general public, who are making investment decisions based on incomplete data. Despite being illegal, insider trading is challenging to detect and prove. Insiders often use complex networks to obscure their activities, making it hard for regulators to identify patterns of abuse.

However, insider trading carries heavy penalties, including fines and jail time, in most countries. Regulatory bodies, such as the Securities and Exchange Commission (SEC) in the United States and the Securities and Exchange Board of India (SEBI), actively monitor and investigate suspicious trading activity to detect and deter insider trading.

Conclusion

The above mentioned tactics not only harm individual investors but also erode public trust in financial markets. While regulators work tirelessly to detect and punish such behavior, the ever-evolving complexity of trading strategies makes it challenging to fully eradicate market manipulation.

As investors, staying informed, conducting thorough research, and exercising caution are essential steps in protecting one’s financial interests in a market susceptible to manipulation.
