What Is Short Selling?

The Basics of Short Selling

Short selling (or “shorting”) is a way to make money when a stock or security’s price goes down. It’s the opposite of the traditional investing approach where you buy low and sell high. Instead, with short selling, you sell first and buy later—hoping the price drops so you can buy back at a cheaper price.

What Can Be Shorted?

You can short a variety of securities, including:

• Stocks
• Forex pairs
• Options
• Other tradable assets

For simplicity, we’ll focus on stocks in this guide.

How Does Short Selling Actually Work?

Step-by-Step Example: John and Flubaroo

Imagine John, an investor, is looking at shares of a hypothetical ride-sharing company called Flubaroo, currently trading at $100 per share.

One day, John hears from a judge who has the power to change laws that 70% of Flubaroo’s business might get banned soon. This insider-like tip makes John believe Flubaroo’s stock price will drop drastically.

Borrowing Shares to Sell

John contacts his broker (like TD Ameritrade or Ally Invest) and borrows 100 shares of Flubaroo. This borrowing happens through a margin account—a special account that allows you to borrow securities or money with regulatory requirements to maintain certain funds.

John immediately sells those 100 shares at the current market price of $100 per share, getting $10,000 in cash.

Buying Back Shares to Return

After the legislation passes, Flubaroo’s price plummets to $50 per share. Now, John buys 100 shares back at $50 each, paying $5,000 to get them.

John returns the 100 shares to the broker, fulfilling his obligation.

John’s Profit

Since John sold high ($100) and bought low ($50), his profit is the difference: $10,000 from selling minus $5,000 to buy back = $5,000 profit.

What If the Stock Price Goes Up?

The risk with short selling is that if the stock price rises instead of dropping, John loses money. Say Flubaroo skyrockets to $150 per share instead of falling.

John still needs to buy back 100 shares to return to the broker, but now it costs him $15,000 instead of the original $10,000 he sold for.

This means John loses $5,000.

Because there’s no upper limit to how high a stock price can go, potential losses from short selling can technically be unlimited.

Understanding Margin Accounts and Regulations

What Is a Margin Account?

A margin account lets you borrow money or securities from your broker. It’s regulated by FINRA, meaning brokers require you to maintain a minimum balance and follow certain rules to keep your account in good standing.

Why Is This Important?

You must have a margin account to short sell, and brokers may charge interest on the borrowed shares. Plus, if your losses grow too big, you might face a margin call where you have to deposit more funds or close your positions.

Pros and Cons of Short Selling

Pros of Short Selling

• Potential for high profits: If your predictions are correct, you can make money when stock prices drop.
• Lower initial capital needed: You don’t need to buy shares outright; you borrow them.
• Hedging tool: If you own a stock long-term but expect short-term dips, short selling can protect your portfolio by offsetting losses during downturns.

Cons of Short Selling

• Unlimited loss potential: Stocks can rise infinitely, meaning losses can grow without limit.
• Need for a margin account: This involves regulatory requirements, interest fees, and potential margin calls.
• Interest costs: Borrowing shares isn’t free; you may pay interest while holding the short position.
• Complex and risky: Short selling is more technical than regular investing and requires careful monitoring.

When Should You Consider Short Selling?

Short selling isn’t for everyone. It’s best suited for:

• Experienced investors who understand market risks
• Traders looking to hedge existing long positions
• Investors who have strong reasons or insights that a stock will decline
• Those prepared to handle margin requirements and potentially large losses

Short Selling Strategy Tips

1. Do your research: Make sure you understand the company, market conditions, and potential catalysts for the price drop.
2. Use stop-loss orders: Protect yourself from runaway losses by setting limits on how much loss you’re willing to accept.
3. Keep an eye on news: Legislation, earnings reports, or other events can quickly change a stock’s price.
4. Understand margin calls: Know your broker’s policies and be financially prepared in case you need to add funds.
5. Consider the timing: Short selling often works best for short-term trades or hedging, not long-term holds.

Short Selling vs. Long-Term Investing

While long-term investing focuses on buying companies you believe in and holding them for years, short selling is about capitalizing on short-term declines. Both strategies have their place, and many savvy investors combine them to balance risk and gain opportunities in different market environments.

Final Thoughts

Can I short sell any stock?

Not always. Some stocks have restrictions, may be hard to borrow, or brokers may limit your ability to short certain securities.

You must return the borrowed shares. If you fail to do so, your broker can force-close your position, which may result in losses or penalties.

How much money do I need to start short selling?

You need a margin account, which requires a minimum balance (usually several thousand dollars), plus enough funds to cover potential losses.

Is short selling legal?

Yes, short selling is legal and regulated by financial authorities, but it must be done following specific rules and regulations.

Summary

Short selling is essentially betting a stock price will fall. You borrow shares, sell them, and then buy them back later at a hopefully cheaper price to return to your broker, pocketing the difference. While it offers opportunities for profit and risk management, it also carries the risk of unlimited losses and requires a margin account with strict rules.

Understanding how short selling works can help you diversify your investment strategies and better navigate the markets—just remember to approach it with caution, research, and an awareness of the risks involved.
