Shorting is a high-risk and expensive investment strategy that hedge funds specialize in

Many hedge funds use short selling as an alternative investment strategy to offset risk

Hedge funds typically use a "long-short" investment strategy—where funds diversify by investing in a mix of long positions and short positions—to balance risk and maximize profits. Including short positions gives hedge funds some protection against downturns in the market, although the strategy can have uncapped losses for investors.

Hear why some experts and investors think short selling keeps the market healthy

Despite criticism that short selling incentivizes downturns in the market, many experts and investors say that short selling is a critical aspect of price discovery and market efficiency. These experts and investors say that short sellers help detect fraud and prevent stocks from becoming overvalued.

Retail investors are getting burned by long/short strategies

Investors need a 'margin account' to short sell stock

Margin accounts are leveraged accounts through brokerage firms that allow investors to make trades without the full amount of capital on hand. Similar to a secured loan, margin accounts often require some form of collateral and typically have a cap on how much investors can borrow. However, trading with a margin account is much riskier than a traditional investment account. Fees and charged interest are due on margin accounts, regardless of trade performance, meaning it's possible for investors to lose more money than just their initial investment.

A short squeeze happens when short sellers increase stock prices by buying shares back quickly

When short sellers realize their positions may be incorrect—usually triggered by increasing share prices—they often try to quickly buy back their shares in order to minimize their total losses. When this happens on a large scale, that buying activity can drastically increase to represent the seemingly high demand for that stock. The result is called a "short squeeze," which refers to short sellers literally being squeezed out of their positions by rising prices.

Hedge funds, the private investment firms that trade a wide swath of financial assets, make money by imposing steep fees on investors and from the fund's investment performance.

As a result, investors may be hesitant to invest in the company in the future, creating a feedback loop of stock downturn.
