🪙Ethics in Accounting and Finance Unit 8 – Insider Trading & Market Manipulation

Insider trading and market manipulation undermine fair markets, eroding public trust and creating an uneven playing field. These practices distort prices, leading to inefficient capital allocation and severe consequences for violators, including fines and imprisonment. Key concepts include material non-public information, tipping, and misappropriation. Legal frameworks like the Securities Exchange Act and Regulation Fair Disclosure aim to prevent these practices. Common schemes range from classic insider trading to pump-and-dump tactics and spoofing.

What's the Big Deal?

  • Insider trading undermines fair and efficient markets by giving unfair advantages to those with access to material non-public information
  • Erodes public trust in the integrity of financial markets, discouraging participation and investment
  • Creates an uneven playing field, benefiting insiders at the expense of ordinary investors
  • Distorts market prices, leading to inefficient allocation of capital and resources
  • Insider trading scandals can damage the reputation of companies, individuals, and entire industries
  • Enforcement actions and penalties for insider trading violations can be severe, including hefty fines and imprisonment
  • Ethical concerns arise from the misuse of confidential information for personal gain, breaching fiduciary duties and violating principles of fairness and transparency

Common Insider Trading Schemes

  • Classic insider trading: Corporate insiders (officers, directors, employees) trade on material non-public information obtained through their positions
  • Tipping chains: Insiders pass material non-public information to others (tippees), who then trade on the information or pass it along to subsequent tippees
  • Misappropriation: Outsiders (lawyers, accountants, consultants) misappropriate confidential information from their clients or sources and trade on it
  • Front-running: Broker-dealers or investment professionals trade ahead of large client orders that are likely to move market prices
  • Insider trading rings: Groups of individuals, often across multiple companies or industries, share and trade on inside information
  • Hacking and cyber theft: Obtaining material non-public information through illegal hacking of computer systems or networks
  • Shadow trading: Trading in the securities of a company based on material non-public information about a related company (supplier, competitor)

Market Manipulation Tactics

  • Pump and dump: Artificially inflating the price of a security through false or misleading statements, then selling at the higher price
  • Wash trading: Simultaneously buying and selling the same security to create the appearance of active trading and manipulate prices
  • Spoofing: Placing large orders to buy or sell a security with no intention of executing them, creating a false sense of demand or supply
  • Painting the tape: Engaging in a series of transactions reported on a public display facility to give the impression of activity or price movement
  • Scalping: A securities trading practice that involves a trader trading in and out of a position several times a day with the intention of making small profits

  • Churning: Excessive trading by a broker in a client's account to generate commissions, disregarding the client's investment objectives
  • Corners and squeezes: Acquiring a dominant position in a security to manipulate its price, forcing short sellers to cover at artificially high prices
