Short Selling

Short Selling Is Essential for Healthy Markets

Short selling is a regulated and widely used strategy. Investors use short selling when they believe, based on fundamental research, that a stock price is overvalued. Short selling promotes liquidity, stabilizes markets, and helps investors and companies reduce risk in their portfolios.

Some short sellers also conduct in-depth research and analysis that exposes financial fraud and corruption, including in the Enron, Valeant, and Wirecard corporate corruption scandals. Additionally, short sellers correctly indicated the U.S. housing market was overvalued before the 2007-2008 financial crisis.

Regulators have long recognized the vital role of short selling to help markets function efficiently. The practice of short selling is well regulated. It has the proper oversight and transparency that allows the strategy to benefit a wide array of investors.

Securities laws give the SEC the authority to gain access to trading information and to prevent market manipulation. Permitting short selling, particularly with the current robust regulatory framework, means that investors can manage risks better and markets can factor in the broadest possible views about a particular stock, bond, or index – reducing the likelihood of bubbles forming.

What is short selling?

How short selling works

Investors most commonly use “short” positions to express a view that a security, such as a stock, is overvalued.

When an investor “shorts” a stock, the following happens:

Graphic demonstrating the process of short selling. It includes icons representing the entities involved, including an Institutional Investor, Broker, Short Seller, and the marketplace. Arrows between the icons represent each step involved in the short sale process. The Institutional investor lends long positioned stocks to a broker. The broker lends 10 shares of ABC Stock to a short seller. Short seller sells 10 shares of ABC Stock for $500. The stock then loses value in the marketplace. The short seller then buys 10 shares of ABC Stock for $400 and returns the 10 shares of ABC stock to the broker, keeping $100. The $100 is received by the institutional investor as payment for lending the original long positioned stocks.

If the share price of the shorted stock goes down, the investor will receive a profit equal to the difference between the money they received when selling the borrowed shares and the cost of repurchasing the shares at a lower price.

If the share price rises, the investor will incur a loss as they will have to repurchase the shares at a higher price than the amount they received from selling the borrowed shares.

Short selling benefits society, markets, and people

Hedge funds may decide to short a stock for a variety of reasons. In some cases, they uncovered fraud or illicit business practices through highly sophisticated research. In fact, short sellers played a key role in uncovering fraud in the EnronWirecard, and Valeant scandals.

In other cases, investors may take a short position because they believe a company’s management is not adapting to technological advances or emerging threats.

Hedge funds use short selling to deliver returns and shield their investors — including pensions, foundations, and endowments — from market volatility and asset bubbles. These same investors also earn money from lending securities to short sellers, boosting returns for their beneficiaries.

As a result, short selling helps protect the retirement security of 26 million Americans, advance educational opportunities for tens of thousands of students, and support the missions of thousands of nonprofits across the country.
