Short Sale: Definition, Example, Risks, and Margin Requirements

Because you’re borrowing shares from a brokerage firm, you must first establish a margin account to hold eligible bonds, cash, mutual funds, and/or stocks as collateral. As with other forms of borrowing, you’ll be charged interest on the value of the outstanding shares until they’re returned (though the interest may be tax-deductible). Interest accrues daily at the prevailing rate and is deducted from your account on a monthly basis. Typically, you might decide to short a stock because you feel it is overvalued or will decline for some reason. The short seller then quickly sells the borrowed shares into the market and hopes that the shares will fall in price.

A month later, the stock had declined to $400, and the trader decided to cover the short position by buying the stock back for $400 in cash. Short selling, or shorting, a stock or another type of security is straightforward in theory, but it presents different costs and risks from going long. As noted above, the cost to borrow a stock changes frequently in response to supply and demand conditions. For example, you could log off one night with a short position carrying a 20% interest rate, only to log in the next day to find it has surged to 85%.

The stock price quickly rises to $80 a share, leaving the investor with a loss of $15 per share for the moment. Short selling was restricted by the “uptick rule” for almost 70 years in the United States. Implemented by the SEC in 1938, the rule required every short sale transaction to be entered into at a price that was higher than the previous traded price, or on an uptick. The rule was designed to prevent short sellers from exacerbating the downward momentum in a stock when it is already declining. It’s a relatively sophisticated (and risky) trading maneuver that requires a margin account and a keen understanding of the stock market.

  1. If your hunch is wrong and the price rises, you are out the difference.
  2. Short selling is an advanced trading strategy investors use when they speculate whether the price of a stock is going down.
  3. When you pay back your broker, you need to pay him back the borrowed shares plus a small interest fee.
  4. This is a publicly available list of securities with FTDs for five or more consecutive trading days and is used by regulators to identify potential cases of market manipulation.

On the other hand, if the stock price decreases, funds can be withdrawn from the account or be reinvested. Although stocks can also be used to meet the margin requirements, not all of them are, and the broker will be the one determining the margin value. Broker margin requirements are complex, but necessary to protect market liquidity as a whole. Short sale margin begins with an initial margin of 150 percent of the stock sale price. Stocks that are heavily shorted are vulnerable to a short squeeze, which can cause them to go up by many hundreds of percent in a short amount of time. Although you should be able to close your position just fine, these restrictions could cause the stock to go up, and you may need to close your position at a loss.

Risk-reward payoff

You “borrow” 10 shares of Meta from a broker and then sell the shares for the market price of $200. Let’s say all goes as planned, and later, you buy back the 10 shares at $125 after the stock price has gone down and return the borrowed shares to the broker. Closing a short position can be up to the short seller, however, certain brokers/lenders will include provisions requiring the return of funds if requested in a margin call. Another requirement from the brokerage/lender is a margin account (i.e. maintenance margin), which is the minimum equity required to be held by the short seller post-transaction. As potential losses on a short sale are unlimited, a margin call effectively limits how much loss your position can sustain.

If an investor’s account value falls below the maintenance margin, more funds are required, or the broker might sell the position. Experienced investors frequently engage in short selling for both purposes simultaneously. Hedge funds are among the most active short sellers and often use shorts in select stocks or sectors to hedge their long positions in other stocks. To sum up, short positions are bearish strategies since the stock is required to fall for the investor to profit.

Both short-selling metrics help investors understand whether the overall sentiment is bullish or bearish for a stock. Under the new rules limits will be put on so-called “short-selling” from Monday. Vehicles for passive investing, such as exchange-traded funds, guarantee safer bets through fixed returns and fewer losses. For example, if Joe is long ABC, he might also hedge his holdings with an equivalent or comparable short in order to cover his losses if the ABC’s price fails to appreciate.

Short squeezes

The short interest ratio jumped from less than 1% to more than 3.5% in late 2015 as short sellers began anticipating a decline in the stock. By the middle of 2016, GE’s share price had topped out at $33 per share and began to decline. By February 2019, GE had fallen to $10 per share, which would have resulted in a profit of $23 per share for any short sellers lucky enough to short the stock near the top in July 2016.

Using margin provides leverage, which means the trader does not need to put up much of their capital as an initial investment. If done carefully, short selling can be an inexpensive way to hedge, providing a counterbalance to other portfolio holdings. Apart from speculation, short selling has another useful purpose—hedging—often perceived as the lower-risk and more respectable avatar of shorting. The primary objective of hedging is protection, as opposed to the pure profit motivation of speculation. Hedging is undertaken to protect gains or mitigate losses in a portfolio, but since it comes at a significant cost, the vast majority of retail investors do not consider it during normal times. The maximum profit you can make from short selling a stock is 100% because the lowest price at which a stock can trade is $0.

How to Short the Market

While the steps inherent to shorting the stock are the same, the goal is somewhat different. Short selling as part of a hedging strategy will help protect some gains or mitigate losses, depending on whether what happens if i buy tesla stock today prices go up or down. If a stock’s price goes up instead of down, the short seller will lose money—and that doesn’t even include the fees to borrow shares that are part of this trading strategy.

If you own a stock in a particular industry but want to hedge against an industrywide risk, then shorting a competing stock in the same industry could help protect against losses. Shorting a stock can also be better from a tax perspective than selling your own holdings, especially if you anticipate a short-term downward move for the share price that will likely reverse itself. There are the costs of borrowing the bond or stock security to sell, the interest payable on the margin account that holds it, and trading commissions. The margin rule requirements for short sales dictate that 150% of the value of the shares shorted needs to be initially held in the account. Therefore, if the value of the shares shorted is $25,000, the initial margin requirement would be $37,500. This prevents the proceeds from the sale from being used to purchase other shares before the borrowed shares are returned.

The process of locating shares that can be borrowed and returning them at the end of the trade is handled behind the scenes by the broker. Opening and closing the trade can be done through the regular trading platforms with most brokers. However, each broker will have qualifications the trading account must meet before allowing margin trading. For example, Seth Klarman, a hedge fund billionaire who runs Baupost, an investment group, says that short selling is necessary to counter bull markets.
