Front-running is a deceptive and unethical practice that threatens the integrity and fairness of financial markets. The consequences for those caught engaging in front-running are severe, including legal penalties and reputational damage. Preventing front-running requires a combination of regulatory oversight, transparency initiatives, and ethical behavior within the financial industry. Maintaining trust and confidence in financial markets is vital for their long-term health and stability.

Defining Front-Running

Front-running, in its essence, is the act of placing a trade or order in a financial market based on non-public information about upcoming transactions. The individual or entity engaging in front-running typically has access to information regarding the intentions of other market participants, often clients or investors they are servicing. This advanced knowledge allows them to execute their own trades before the pending orders of their clients or counterparties, taking advantage of the anticipated price movement resulting from the incoming orders.

Key Characteristics of Front-Running

Front-running exhibits several key characteristics that distinguish it from legitimate trading activities:

  1. Advanced Information: Front-runners possess advanced, non-public information about upcoming market orders or transactions. This information can be gained through their position as brokers, intermediaries, or through illicit means.
  2. Self-Interest: Front-runners act in their own self-interest, seeking to profit from the price movement that their actions trigger. Their primary goal is to secure favorable trading outcomes for themselves, often at the expense of their clients or counterparties.
  3. Timing: Timing is crucial in front-running. The front-runner executes their own trade just ahead of the pending order they are aware of, capitalizing on the expected price impact caused by the incoming order.
  4. Profit Motive: The primary motivation behind front-running is financial gain. Front-runners seek to profit from the price movement resulting from their actions, potentially generating substantial profits if the market moves in the expected direction.

Forms of Front-Running

Front-running can take various forms in financial markets, with some of the most common examples being:

  1. Equity Front-Running: In the context of equities (stocks), front-running involves buying or selling shares based on advanced knowledge of a large institutional order. The front-runner executes their own trade before the institutional order is executed, often causing a temporary price move in their favor.
  2. Forex Front-Running: In the foreign exchange market (Forex), front-running occurs when a trader takes advantage of their knowledge of a pending customer order by initiating their own trade before the customer’s order is executed. This can lead to unfavorable exchange rates for the customer.
  3. Cryptocurrency Front-Running: In the world of cryptocurrencies, front-running is prevalent in decentralized exchanges (DEXs). Malicious actors can exploit transaction delays on blockchain networks to front-run trades, profiting from the price movement before the intended trade is completed.
  4. Commodity Front-Running: In commodity markets, front-running can involve advanced knowledge of large commodity orders. Traders may take positions in anticipation of these orders, seeking to benefit from price movements.

Impact on Financial Markets

Front-running can have several significant impacts on financial markets:

  1. Market Integrity: Front-running undermines market integrity by providing unfair advantages to those with access to advanced information. This erodes trust in the fairness and transparency of financial markets.
  2. Loss of Investor Confidence: When investors or clients suspect that front-running is occurring, it can lead to a loss of confidence in the financial system. This can result in reduced participation in the market and decreased investment.
  3. Reduced Liquidity: Front-running can deter market participants from executing large orders, fearing that their intentions will be exploited. This can reduce market liquidity, making it more challenging to execute trades at desired prices.
  4. Distorted Prices: The actions of front-runners can distort asset prices, leading to less efficient pricing in financial markets. This can negatively impact all market participants.

Regulatory Measures to Prevent and Detect Front-Running

Regulatory bodies and exchanges have implemented various measures to prevent and detect front-running:

  1. Surveillance Systems: Exchanges employ sophisticated surveillance systems to monitor trading activities and identify suspicious patterns, including potential front-running.
  2. Transaction Timestamps: Precise timestamps on trade orders and executions help regulators track the sequence of trades and identify instances of front-running.
  3. Information Barriers: Financial institutions are required to establish information barriers or “Chinese walls” to prevent the flow of non-public information between departments that could facilitate front-running.
  4. Regulatory Oversight: Regulatory bodies, such as the U.S. Securities and Exchange Commission (SEC), actively investigate and take legal action against individuals and entities engaged in front-running.
  5. Transparency Requirements: Regulatory authorities often require increased transparency in trading activities, including the disclosure of large orders, to deter and detect front-running.
  6. Market Surveillance Reports: Regulatory authorities may require market participants to submit regular reports on their trading activities, helping regulators identify potential instances of front-running.

Challenges and Considerations

Front-running remains a challenging issue in financial markets for several reasons:

  1. Advanced Technology: The use of advanced technology and algorithmic trading has made it easier for front-runners to execute trades with precision and speed, making detection more challenging.
  2. Cryptocurrency Markets: The decentralized and often pseudonymous nature of cryptocurrency markets has made it difficult to regulate and prevent front-running effectively.
  3. Cross-Border Nature: Financial markets operate globally, and front-running can involve transactions across different jurisdictions, making regulatory coordination complex.
  4. Legal Complexity: Proving front-running can be legally complex, as it often requires demonstrating intent and advanced knowledge.


Front-running is a disruptive and unethical trading practice that undermines the integrity and fairness of financial markets. It involves individuals or entities taking advantage of advanced information about pending orders to execute their own trades for personal gain. Regulatory bodies and exchanges have implemented measures to prevent and detect front-running, but it remains a challenge due to advanced technology and evolving market dynamics. Maintaining market integrity and fairness is essential for the trust and confidence of investors and market participants, making the continued vigilance against front-running crucial in the financial industry.


  • Brokerage Firm Scandal: A brokerage firm’s senior executive learns that a major client is about to place a massive buy order for a particular stock. The executive instructs their traders to buy the stock for their personal accounts just before executing the client’s order, causing the stock’s price to rise. Afterward, they sell their shares at a profit, essentially front running the client’s trade.
  • Cryptocurrency Exchange Misconduct: In the world of cryptocurrencies, a staff member at a cryptocurrency exchange gains access to customer order data. They notice a large sell order for a popular cryptocurrency. The staff member buys the cryptocurrency for their personal account before the customer’s order is executed, profiting from the subsequent price increase.
  • Mutual Fund Front Running: A mutual fund manager receives advance knowledge of significant changes in their fund’s portfolio. They use this information to make personal trades in the stocks they are about to buy or sell on behalf of the fund, gaining an advantage over other investors.
  • Government Official Insider Trading: A government official is aware that a significant policy announcement will negatively impact a certain industry. The official short sells stocks in that industry before the announcement is made public, profiting from the subsequent drop in stock prices.
  • Investment Bank Employee Misconduct: An employee at an investment bank learns that a large institutional client is about to execute a significant trade that will affect the bond market. They purchase bonds for their personal account ahead of the client’s trade, profiting from the price increase caused by the client’s transaction.
  • Hedge Fund Front Running: A hedge fund manager gains access to the fund’s upcoming trades. They execute personal trades that mimic the fund’s actions just before the fund enters the market, ensuring that their personal accounts benefit from the fund’s profitable trades.

Connected Financial Concepts

Circle of Competence

The circle of competence describes a person’s natural competence in an area that matches their skills and abilities. Beyond this imaginary circle are skills and abilities that a person is naturally less competent at. The concept was popularised by Warren Buffett, who argued that investors should only invest in companies they know and understand. However, the circle of competence applies to any topic and indeed any individual.

What is a Moat

Economic or market moats represent the long-term business defensibility. Or how long a business can retain its competitive advantage in the marketplace over the years. Warren Buffet who popularized the term “moat” referred to it as a share of mind, opposite to market share, as such it is the characteristic that all valuable brands have.

Buffet Indicator

The Buffet Indicator is a measure of the total value of all publicly-traded stocks in a country divided by that country’s GDP. It’s a measure and ratio to evaluate whether a market is undervalued or overvalued. It’s one of Warren Buffet’s favorite measures as a warning that financial markets might be overvalued and riskier.

Venture Capital

Venture capital is a form of investing skewed toward high-risk bets, that are likely to fail. Therefore venture capitalists look for higher returns. Indeed, venture capital is based on the power law, or the law for which a small number of bets will pay off big time for the larger numbers of low-return or investments that will go to zero. That is the whole premise of venture capital.

Foreign Direct Investment

Foreign direct investment occurs when an individual or business purchases an interest of 10% or more in a company that operates in a different country. According to the International Monetary Fund (IMF), this percentage implies that the investor can influence or participate in the management of an enterprise. When the interest is less than 10%, on the other hand, the IMF simply defines it as a security that is part of a stock portfolio. Foreign direct investment (FDI), therefore, involves the purchase of an interest in a company by an entity that is located in another country. 


Micro-investing is the process of investing small amounts of money regularly. The process of micro-investing involves small and sometimes irregular investments where the individual can set up recurring payments or invest a lump sum as cash becomes available.

Meme Investing

Meme stocks are securities that go viral online and attract the attention of the younger generation of retail investors. Meme investing, therefore, is a bottom-up, community-driven approach to investing that positions itself as the antonym to Wall Street investing. Also, meme investing often looks at attractive opportunities with lower liquidity that might be easier to overtake, thus enabling wide speculation, as “meme investors” often look for disproportionate short-term returns.

Retail Investing

Retail investing is the act of non-professional investors buying and selling securities for their own purposes. Retail investing has become popular with the rise of zero commissions digital platforms enabling anyone with small portfolio to trade.

Accredited Investor

Accredited investors are individuals or entities deemed sophisticated enough to purchase securities that are not bound by the laws that protect normal investors. These may encompass venture capital, angel investments, private equity funds, hedge funds, real estate investment funds, and specialty investment funds such as those related to cryptocurrency. Accredited investors, therefore, are individuals or entities permitted to invest in securities that are complex, opaque, loosely regulated, or otherwise unregistered with a financial authority.

Startup Valuation

Startup valuation describes a suite of methods used to value companies with little or no revenue. Therefore, startup valuation is the process of determining what a startup is worth. This value clarifies the company’s capacity to meet customer and investor expectations, achieve stated milestones, and use the new capital to grow.

Profit vs. Cash Flow

Profit is the total income that a company generates from its operations. This includes money from sales, investments, and other income sources. In contrast, cash flow is the money that flows in and out of a company. This distinction is critical to understand as a profitable company might be short of cash and have liquidity crises.


Double-entry accounting is the foundation of modern financial accounting. It’s based on the accounting equation, where assets equal liabilities plus equity. That is the fundamental unit to build financial statements (balance sheet, income statement, and cash flow statement). The basic concept of double-entry is that a single transaction, to be recorded, will hit two accounts.

Balance Sheet

The purpose of the balance sheet is to report how the resources to run the operations of the business were acquired. The Balance Sheet helps to assess the financial risk of a business and the simplest way to describe it is given by the accounting equation (assets = liability + equity).

Income Statement

The income statement, together with the balance sheet and the cash flow statement is among the key financial statements to understand how companies perform at fundamental level. The income statement shows the revenues and costs for a period and whether the company runs at profit or loss (also called P&L statement).

Cash Flow Statement

The cash flow statement is the third main financial statement, together with income statement and the balance sheet. It helps to assess the liquidity of an organization by showing the cash balances coming from operations, investing and financing. The cash flow statement can be prepared with two separate methods: direct or indirect.

Capital Structure

The capital structure shows how an organization financed its operations. Following the balance sheet structure, usually, assets of an organization can be built either by using equity or liability. Equity usually comprises endowment from shareholders and profit reserves. Where instead, liabilities can comprise either current (short-term debt) or non-current (long-term obligations).

Capital Expenditure

Capital expenditure or capital expense represents the money spent toward things that can be classified as fixed asset, with a longer term value. As such they will be recorded under non-current assets, on the balance sheet, and they will be amortized over the years. The reduced value on the balance sheet is expensed through the profit and loss.

Financial Statements

Financial statements help companies assess several aspects of the business, from profitability (income statement) to how assets are sourced (balance sheet), and cash inflows and outflows (cash flow statement). Financial statements are also mandatory to companies for tax purposes. They are also used by managers to assess the performance of the business.

Financial Modeling

Financial modeling involves the analysis of accounting, finance, and business data to predict future financial performance. Financial modeling is often used in valuation, which consists of estimating the value in dollar terms of a company based on several parameters. Some of the most common financial models comprise discounted cash flows, the M&A model, and the CCA model.

Business Valuation

Business valuations involve a formal analysis of the key operational aspects of a business. A business valuation is an analysis used to determine the economic value of a business or company unit. It’s important to note that valuations are one part science and one part art. Analysts use professional judgment to consider the financial performance of a business with respect to local, national, or global economic conditions. They will also consider the total value of assets and liabilities, in addition to patented or proprietary technology.

Financial Ratio



The Weighted Average Cost of Capital can also be defined as the cost of capital. That’s a rate – net of the weight of the equity and debt the company holds – that assesses how much it cost to that firm to get capital in the form of equity, debt or both. 

Financial Option

A financial option is a contract, defined as a derivative drawing its value on a set of underlying variables (perhaps the volatility of the stock underlying the option). It comprises two parties (option writer and option buyer). This contract offers the right of the option holder to purchase the underlying asset at an agreed price.

Profitability Framework

A profitability framework helps you assess the profitability of any company within a few minutes. It starts by looking at two simple variables (revenues and costs) and it drills down from there. This helps us identify in which part of the organization there is a profitability issue and strategize from there.

Triple Bottom Line

The Triple Bottom Line (TBL) is a theory that seeks to gauge the level of corporate social responsibility in business. Instead of a single bottom line associated with profit, the TBL theory argues that there should be two more: people, and the planet. By balancing people, planet, and profit, it’s possible to build a more sustainable business model and a circular firm.

Behavioral Finance

Behavioral finance or economics focuses on understanding how individuals make decisions and how those decisions are affected by psychological factors, such as biases, and how those can affect the collective. Behavioral finance is an expansion of classic finance and economics that assumed that people always rational choices based on optimizing their outcome, void of context.
