Front Running
Front running is the illegal practice where a broker, dealer, or fund manager executes trades in a security for their own or a related account based on advance knowledge of pending client orders that are large enough to move the market price, thereby profiting at the client's expense.
Front running is fundamentally a breach of fiduciary duty and a form of securities fraud. The front runner leverages information asymmetry — knowing that a large client order is about to hit the market — to trade ahead of that order and profit from the predictable price impact. For example, if a fund manager knows that a large institutional order to purchase 1 million shares of Infosys will be executed shortly, front running involves buying Infosys shares in a personal account before placing the client's order, then selling once the client's order pushes the price up.
SEBI has pursued several significant front-running cases in Indian capital markets. One of the most high-profile involved a dealer at a leading domestic mutual fund AMC who was found to have front run large trades being executed on behalf of the fund's schemes. SEBI's investigation, concluded in the early 2020s, documented a pattern where the dealer obtained advance knowledge of upcoming AMC orders and traded in related-party accounts before those orders were executed. SEBI imposed heavy penalties, disgorgement orders, and debarment from the securities market in such cases.
Front running is particularly damaging in the mutual fund context because it directly reduces returns to unit holders. When a front runner buys ahead of the fund's purchase order, the fund ends up buying at a higher price than it otherwise would have. When the front runner sells ahead of the fund's sell order, the fund receives a lower price. Over time, these incremental cost increases compound and erode investor returns.
Preventing front running requires robust internal controls at market intermediaries. These include information barriers (Chinese walls) between trading and sales desks, pre-clearance requirements for personal trades by employees with access to client order flow, surveillance systems that compare employee trading patterns with client order timing, and strict policies on mobile phone usage on trading floors.
SEBI has strengthened its surveillance capabilities through the Integrated Market Surveillance System (IMSS) and cooperation with depositories and stock exchanges to trace trading accounts, beneficial owners, and communication records. The proliferation of algorithmic trading has made front running more difficult to execute manually but has introduced algorithmic front-running concerns in high-frequency trading contexts.
