Stock Market Operators: Definition, Types, How to Find, Price Manipulation
By Arjun Arjun Remesh | Reviewed by Shivam Shivam Gaba | Updated on June 4, 2024

Stock market operators are a group of institutional investors, high-frequency traders, arbitrageurs, hedgers, market makers, and brokers who employ various strategies to buy and sell stocks and capitalize on opportunities in the marketplace. Stock market operators utilize complex statistical models, leverage, derivatives, and automated algorithms to enhance liquidity, reduce inefficiencies, manage risk, and optimize returns. 

Most operators conduct legal practices that contribute to stable, transparent markets, but some unscrupulous operators artificially inflate trading volumes, disseminate misleading information, place fake orders, and exploit insider data to deliberately manipulate stock prices and deceive ordinary investors. Tactics like pump-and-dump schemes, spoofing, layering, wash trading, and trading on confidential information undermine market integrity and fairness. 

Identifying sudden surges in volume, abnormal price patterns, hype-driven stock promotions, and limited delivery percentages can help uncover when manipulation may be occurring. Investors protect themselves by thoroughly researching investments, diversifying holdings across asset classes, avoiding tips from unverified sources, and reporting suspicious activities to regulators tasked with maintaining orderly markets. 

Who are the Stock Operators?

Stock operators are large scale investors or traders who inflate or deflate the stock price by increasing the volume of trades. Stock operators don’t directly manage the price, as it is determined by supply and demand. They rather manipulate the stock market through large volumes. In India, it is unlawful to manipulate the stock market, especially for activities like defrauding. 

What are the different types of Stock Operators?

Institutional Investors, Market Makers, High Frequency Traders, Arbitrageurs, Hedgers, and Brokers are the main type of stock operators. Below are more details about each.

1. Institutional Investors

Institutional investors refer to large organizations that invest money on behalf of others. Institutional investors are considered important stock market operators due to the huge amounts of money they invest. Their buying and selling of large blocks of shares can significantly influence stock prices and the overall direction of the stock market.

When institutional investors are optimistic about the future prospects of a company or the overall economy, they purchase large quantities of shares, which pushes stock prices upward. Conversely, when they become pessimistic, they sell-off holdings, which puts downward pressure on stock prices. Both retail investors and corporations closely monitor institutional investors‘ movements due to their high trading volumes. Their investment decisions have the power to drive broader market sentiment and trends.

2. Market Makers

Market makers are important stock market operators that provide liquidity in the market. As market intermediaries, they create markets for securities by offering to buy and sell securities on a regular and continuous basis. This allows investors to rapidly purchase and sell their stock holdings whenever they want. Market makers operate by simultaneously providing both buy and sell quotes for a particular stock, thereby ensuring there are always potential counterparties available for trades. 

Due to their activities, market makers are crucial for the smooth functioning of the stock market. They reduce volatility by absorbing heavy trading volumes during volatile periods. This prevents abrupt fluctuations in stock prices. Their timely quotes add transparency to price discovery in the market. Market makers also earn profits from the difference between their buy and sell quotes, giving them an incentive to continuously provide liquidity. Their ability to balance supply and demand helps maintain an orderly market. Market makers bring stability and reduce trading risks, boosting investor confidence in the marketplace. Their role as intermediaries is vital to the efficient functioning of the stock market.

3. High Frequency Traders

High-frequency traders use sophisticated computer algorithms and ultra-fast data connections to transact a large number of orders within fractions of a second. High-frequency traders aim to profit from small differences in stock prices across exchanges and arbitrage opportunities in the market. 

As market operators, high-frequency traders influence stock market movements. Through their algorithms, they detect emerging price patterns and shifting market sentiments at lightning speed. This allows them to consistently bet on short-term price movements and fluctuations. At times, their massive computer-generated orders can temporarily overwhelm market depth and liquidity, causing sudden price swings. However, high-frequency traders also enhance market efficiency by enabling prices to rapidly adjust to new information and bring supply and demand into equilibrium across exchanges. High Frequency Trading significantly impacts stock market dynamics, and the role of High Frequency Trading in enhancing market efficiency cannot be overlooked.

4. Arbitrageurs

Arbitrageurs are institutional investors who seek to profit from temporary price differences between similar or identical financial instruments trading on different markets or in different forms. They analyse markets for situations where identical securities are trading at different prices on different exchanges or in different jurisdictions.

They simultaneously buy the lower-priced instrument and sell the higher-priced instrument, then wait for the prices to converge, pocketing the difference. This activity helps to reduce inefficiencies in pricing and brings parity, improving market liquidity and transparency. Types of Traders, such as arbitrageurs, often find these opportunities exist only momentarily, so Types of Traders use high-speed computerized trading systems and algorithms to exploit these very small windows.

5. Hedgers

Hedgers are stock market operators whose main goal is to reduce or eliminate the risk of financial losses from their investments. Hedgers do this by taking opposing positions in related financial instruments to offset potential losses. A hedger would employ various risk management strategies to offset investments that carry inherent volatility. They may short-sell stocks that are negatively correlated to positions in their portfolio.

So if the market declines, one holding increases in value to offset losses in another. Hedgers also make extensive use of options to limit their exposure to downside price movements. Through hedging techniques, they can neutralise uncertainty and concentrate on the core operations of their business without worrying about unpredictable swings in the financial or commodity markets. Their priority is decreasing hazards, not taking bold bets for big profits.

6. Brokers

Brokers are stock market operators who connect buyers and sellers by facilitating and executing trade orders on their behalf. As intermediaries in financial transactions, brokers work for either buy-side or sell-side clients, taking commissions for matching trades. As a stock market operator working as a broker, the main role would be matching trade orders between investors.

This could involve tasks like finding institutional or retail buyers for large sell orders from corporations, advising independent traders on entry and exit points, or executing transactions for managed portfolios. Brokers have to keep up-to-date on market news and trends to spot opportunities that meet their clients’ objectives. Their expertise lies in navigating the exchange environment and infrastructure, understanding different order types, and ensuring the best execution of deals within regulatory guidelines. 

Their strategies and activities, whether providing liquidity, seeking arbitrage opportunities, hedging risks, or matching buyer and seller orders, all collectively contribute to the efficient functioning of stock markets. Stock Brokers play a crucial role in these activities, ensuring smooth transactions and market stability. Additionally, Stock Brokers facilitate access to market opportunities for individual and institutional investors alike.

How do you find the operator of a stock?

Stock operators typically inflate the price of a stock by creating high trading volumes and then suddenly dump their shares onto unsuspecting retail investors, causing the price to plummet. Here’s how you can identify the intent of stock operators:

Volume Analysis

Keep a close eye on the trading volume of a stock. Abnormally high volume without any significant news or events could be a signal that operators are at work, artificially inflating the price.

Delivery Analysis

Check the delivery data, which represents the actual transfer of shares from one account to another. The delivery percentage is low in comparison to the trading volume

indicates that operators may have orchestrated intraday trading or speculation to produce the high volume.

Price Action

Observe the price movement of the stock. If you see a stock exhibiting continuous upward circuits or rallying without any fundamental justification, it could be a sign of price manipulation by operators.

Social Media Hype

Be wary of stocks that are heavily promoted on social media platforms, Telegram groups, or WhatsApp groups, as operators often use these channels to create buzz and lure in retail investors.

Low-Priced Stocks

Operators tend to target low-priced stocks with low trading volumes, as they are easier to manipulate due to their relatively low market capitalization and lack of institutional participation.

Investors should prioritize fundamental analysis, technical analysis, and risk management strategies to navigate the stock market successfully.

How Stock Prices are affected by Market Operators?

Order book, day trading, algo trading, pump and dump, and insider trading are five methods stock market operators use to manipulate stock prices. Below are more details about each strategy. 

1. Order Book Strategy

Stock operators often employ order book strategies to manipulate stock prices for their own benefit. One such strategy is spoofing, where they place large buy or sell orders without the intention of executing them. This creates a false impression of supply or demand, luring other traders to act accordingly. Operators then capitalize on the resulting price movement.

Another tactic is layering, where they rapidly enter and cancel orders at different price levels to obscure their true intent. This tricks algorithms into reacting, allowing operators to profit from the ensuing order flow imbalances.

Wash trading is another strategy where operators trade between their own accounts to artificially inflate trading volumes and price levels. This creates a misleading perception of high liquidity and interest in a stock, attracting unsuspecting investors.

2. Day Trading Strategy

 Stock operators use the intraday strategy often. They begin their trading day by scanning the market for stocks that are exhibiting high volatility and volume. Stocks priced between Rs.5-10 that are trading millions of shares per day are ideal. They analyze Level 2 market data for these stocks to identify potential support and resistance levels. 

Just before the stock hits these price levels, they execute quick buy or sell orders, hoping to capture 50 paisa to Rs.2 per share as the stock bounces off the support/resistance. They set tight stop losses of 10-30 paisa to limit potential losses on any given trade. If the trade moves in their favor, they will trail the stop up to lock in profits. 

Traders aim for at least a 2:1 profit loss ratio on each trade. They typically close out all positions before the market closes to avoid holding overnight risk. This style of trading requires mastery of technical analysis, disciplined risk management, and being able to make split-second trading decisions based on observing real-time market dynamics. 

3. Algo Trading Strategy

Stock operators develop automated algorithmic trading strategies to execute trades rapidly and efficiently. These strategies utilize mathematical models and statistical analysis to identify trading opportunities and execute orders without human intervention. The algorithms are coded into software that can monitor markets, analyze data, and place trades automatically based on predefined parameters. 

Operators optimize their algos to capitalize on short-term inefficiencies and price discrepancies in markets. Strategies may involve techniques like statistical arbitrage, pattern recognition, high-frequency trading, and quantitative analysis. The algo is backtested on historical data to validate its profitability before being deployed live. 

Once in operation, the algorithm constantly scans the market for opportunities within its strategy rules. When conditions are met, it initiates orders at lightning speeds while considering trading costs, risks, and capital limitations. Trades are executed in fractions of a second, often across multiple assets and exchanges. 

4. Pump & Dump

Stock operators often employ the “Pump and Dump” scheme to manipulate stock prices illegally. This strategy involves artificially inflating the price of a stock through aggressive promotion and dissemination of misleading information, creating hype, and enticing unsuspecting investors to buy (the “pump” phase). Once the stock price has risen substantially due to increased demand, the operators swiftly sell their shares at the inflated price (the “dump” phase), leaving investors holding overvalued stocks that quickly decline in value.

5. Insider trading

Stock operators employ insider trading as a manipulative strategy to profit from non-public information. This involves exploiting privileged data about a company’s prospects, performance, or major events before it becomes public knowledge. Operators may have direct access as corporate insiders like executives or board members, or gain intel through unofficial channels.

Once in possession of material non-public information, operators will strategically buy or sell shares based on how the undisclosed details are expected to impact the stock price after public release. If the confidential data suggests the price will rise, insiders purchase shares at deflated values. Conversely, if it signals a downturn, they offload holdings prior to the drop.

This unethical practice undermines market integrity by giving certain traders an unfair informational edge over ordinary investors operating only on legitimately public data. 

An informed and cautious approach to investing serves as the best defense against falling victim to market manipulation schemes. Understanding How Stock Prices are Determined? is essential for investors to make sound decisions. By gaining insights into How Stock Prices are Determined?, investors can better navigate the complexities of the stock market and protect their investments.

How do stock market operators manipulate share prices?

Stock Market operators employ manipulative tactics to distort stock prices, such as propagating misleading information to inflate prices (pump and dump schemes), placing fake orders to create artificial supply/demand (spoofing and layering), and exploiting insider information for illicit trades. Investors protect themselves by conducting thorough research, diversifying their portfolios, remaining vigilant against unsolicited promotions, and promptly reporting suspected manipulation to regulatory authorities. Understanding how the Stock Market works can help investors recognize and avoid these manipulative schemes.

Is Stock Operating Illegal?

Stock operating itself is legal, as traders buy and sell stocks to capitalize on market opportunities. However, certain unethical practices like spoofing, wash trading, and manipulative hype are illegal forms of stock trading aimed at deceiving investors. Stock operators engaging in fraudulent activities to rig markets may securities fraud charges and penalties imposed by regulators.
