Before a financial instrument can be sold in a securities exchange, involved parties must overcome the problem of adverse selection. Stocks most readily experience adverse selection in two forms: Traditionally, financial intermediaries mitigate or eliminate adverse selection in the stock market by reducing information costs.

There is one unique and controversial example of adverse selection in some secondary stock market trades: Insider trading is a poorly defined concept with roots in adverse selection theory and the efficient market hypothesis EMH.

There are several problems with this notion. The first two are obvious: Since stock exchanges and regulatory agencies don't want the investing public to believe the game is fixed, there are grounds for safeguards against insider transactions.

This is far easier said than done. Insiders have the best access to information and markets are most efficient when prices reflect accurate and up-to-date information.

Prohibiting insiders from acting on information has the unfortunate consequence of keeping all traders in the dark. Economists disagree about whether this qualifies as adverse selection. Even those who think so don't agree on necessary remedies. Financial intermediaries, such as financial advisers and brokers , reduce adverse selection in several ways.

Intermediaries rate companies and their issues, for example, providing investors with key information about stock value and trustworthiness. London-style stock exchanges create disclosure requirements for issuers in order to attract more traders.

Each exchange has an incentive to foster an atmosphere of fair play.
