What is Painting The Tape?

In the world of investing, the lure of easy money can sometimes lead people down the wrong path. While most traders abide by the rules and norms of ethical market behaviour, some succumb to the temptation to use less scrupulous tactics to manipulate stock prices. One such questionable strategy is known as “painting the tape.” 

At first glance, the stock market might seem totally unpredictable and chaotic. In reality, though, there are certain patterns and mechanisms in place to ensure orderly trading. When misused, however, these very systems can also enable market manipulation in the form of painting the tape. So what exactly does this practice entail, and why should regular investors care? Read on to find out.

Defining the tape

To start, it’s important to understand what “the tape” refers to in stock market terminology. In the old days, a machine called a stock ticker would print out a paper record of every trade on an exchange in real-time. The long, thin strip of paper that came spilling out was dubbed the “ticker tape.” 

While today most trading is done electronically, the idea of a constantly updating “tape” capturing transaction data lives on. Accessible through financial data services, the modern ticker tape provides up-to-the-second information on stock prices, trading volumes, and more. This data allows investors to monitor market activity and identify potential investment opportunities.  

When all is working as intended, the tape reflects normal supply and demand dynamics in an open and fair marketplace. However, the system can also be exploited by traders engaging in painting-the-tape techniques aimed at manipulating prices.

What is painting the tape?

In a nutshell, painting the tape refers to deliberately conducting trades in order to influence a stock’s price or trading volume. The goal is to simulate market interest in order to drive the share price higher or lower. Essentially, it creates an illusion that a stock is more actively traded than it really is.

Painting the tape is an illegal form of market manipulation. However, illicit traders attempt to disguise their actions and avoid detection by exploiting grey areas in securities regulations. Unique trading dynamics, limited surveillance capabilities, and coordination between multiple traders can also enable tape-painting schemes.

Anatomy of a tape painting scheme

Imagine a group of four traders, whom we’ll call Traders A, B, C, and D. Each currently owns a substantial number of shares in Hypothetical Company (ticker: FAKE). After acquiring the stock at around Rs 1800 per share, FAKE has since dropped to a current market price of Rs 400 per share.

Facing significant losses if they sold now, the traders hatch a plan: band together to artificially inflate the stock price, allow unsuspecting investors to get sucked in, and then unload their shares before the price drops back down. Here are the basic steps involved:

1. The traders begin rapidly buying and selling FAKE shares among themselves in high volumes. These wash trades simulate market interest and drive up the price.

2. Seeing heavy trading volume, other traders take notice of FAKE and start buying shares, further pushing up the price. 

3. Once the share price reaches an artificially inflated level, say Rs 1500, the manipulators race to sell their holdings and cash out. 

4. With the primary drivers of demand now gone, the price soon drops back down, leaving late-to-the-game investors holding the bag.

By coordinating intentional wash trading and capitalising on other investors’ reactions, the traders successfully pulled off a tape painting ruse. They managed to eliminate their losses while leaving headaches for unsuspecting market participants.

Of course, this is just a simplified example. In practice, painting the tape schemes can be complex, involving multiple accounts, parties, exchanges, and more. The core goal, however, remains the same – create a mirage of market activity to drive a stock price up or down.

Painting the tape vs. wash trading

In discussing painting the tape market manipulation, the concept of wash trading was mentioned. What exactly is wash trading, and how does it differ from tape painting?

Wash trades refer to buy and sell orders for the same financial instrument that effectively cancel each other out. For example, a trader could simultaneously place equal buy and sell mandates for the same stock at the same price, in effect, trading with oneself. 

These phantom trades don’t result in any actual change in beneficial ownership. Instead, they manipulate market data to give the impression of active trading where there is none.

Like painting the tape, wash trading undermines market integrity and constitutes illegal market manipulation. Both schemes involve conducting trades in order to create misleading market activity. However, painting the tape aims for a broader, more sustained market impact.

Whereas wash trades instantly reverse themselves, tape painting tricks often draw in other investors and can influence share prices for extended periods. Through this “herd effect,” tape painting can manipulate entire investor crowds, while wash trading typically impacts only short-term metrics.

 Why should you care?

At this point, you may be wondering, as long as I steer clear of these deliberate manipulation efforts, why should I care if other traders are playing dirty? How could this impact me as an individual investor?

In reality, manipulation like tape painting poses significant risks even to prudent retail investors. These activities undermine market integrity and price discovery mechanisms, resulting in artificial volatility, skewed valuations, and bubbles. When share prices get manipulated and detached from business fundamentals, average investors often end up overpaying while manipulators profit.

Some specific ways tape painting can hurt everyday investors include:

  • Buying into hype at the wrong times: Fake trading activity tricks investors into piling into “hot” stocks at already-inflated valuations
  • Getting stuck holding overvalued shares: Investors may end up buying high right before manipulators exit, leaving share prices prone to crash. 
  • Contributing to bubbles then suffering the consequences: Short-term manias lead to increased systemic risks that ultimately hurt the average investor
  • Difficulty properly valuing investments: Reliable price signals get distorted, challenging investors’ ability to make informed decisions.

Therefore, painting the tape schemes rig the system against the average investor who relies on free and fair price discovery. Just like insider trading or Ponzi schemes, market manipulation erodes overall trust in capital markets, too. Even if not directly involved, all participants absorb some damage from activities that pollute market integrity.  

Key takeaways of painting the tape

If the intricacies of tape painting seem complex, the key lessons for individual investors remain straightforward:

  • Avoid getting caught up in investment manias centred on questionable trading patterns or volume spikes. Focus analysis on business fundamentals over technical momentum.
  • Temper expectations around abnormally large price swings or volatility. If an outstanding performance looks too good to be true, view it with added scepticism.
  • Diversify across asset classes, sectors, geographies, and investment styles to reduce exposure to manipulation associated with specific stocks or strategies.

Of course, most capital market activity remains above board. But given the incentives to game the system, market misdeeds continue popping up periodically. Understanding and mitigating risks around distorted incentives serves investors well in sidestepping unnecessary troubles.

While chasing the next hot stock might sound tempting, prudent investors steer clear of seemingly “easy money” situations. Because, as the shenanigans around painting the tape demonstrate, if things look too good to be true in the markets, they just might be.


While regulations aim to foster ethical trading practices, isolated incidents of manipulation still slip through the cracks. Painting the tape describes one such market malpractice where traders collude to fabricate trading activity and essentially counterfeit demand. These partygoers then quietly slip out, leaving a massive price hangover for unsuspecting everyday investors.


What does “painting the tape” in the stock market refer to?

Painting the tape refers to traders conducting manipulative trades among themselves to simulate false demand, tricking other investors into pushing up share prices so the manipulators can sell at a profit.

How does a painting tape scheme work to manipulate prices?

Traders coordinate wash trades and buy/sell orders between themselves to inflate trading volumes, making a stock seem popular, so prices rise as outside investors jump in, allowing the inside manipulators to sell out.

Why is the practice called “painting the tape”?

“Painting the tape” means manipulating the stock market by creating fake trading activity and printing false information on paper records of stock prices.

How can individual investors avoid painting the tape traps?

Investors should watch for sudden, abnormal price and volume surges detached from business fundamentals, which may signal manipulation, and avoid buying into short-term investment manias.

Who does painting the tape harm in the markets?

While benefiting manipulative traders, painting the tape hurts everyday investors through overinflated stock valuations, promotion of bubbles and enabling broader market risks, thus eroding overall integrity.
