What is Short Selling?

Short selling is an investment strategy where an investor sells shares they do not own, borrowing them first and buying them back later at a lower price to make a profit.
In simple terms, it's a way to bet on the decline of a stock's price.
If the stock price drops as expected, the investor buys back the shares at a lower cost, returns them to the lender, and pockets the difference.

For example:

• You borrow a stock currently priced at $100 and sell it immediately.
• Later, the stock price falls to $80.
• You buy it back at the lower price and return it to the lender.
• Your profit is $20 per share.

However, if the stock price goes up to $120 instead, you would lose $20 per share.
Short selling allows you to profit from a market decline, but it also carries the risk of unlimited losses if the stock price rises.

📌 How Does Short Selling Work?

Short selling involves the following four steps:

🔹 1️⃣ Borrow the Shares

• The investor borrows shares from a brokerage or an institutional investor.
• The borrowed shares require a margin deposit of 40% to 100% of the stock's value as collateral.

🔹 2️⃣ Sell the Shares

• The borrowed shares are sold at the current market price to secure cash.
• Since you don’t own the shares, any price movement affects your position.

🔹 3️⃣ Buy Back the Shares at a Lower Price

• If the stock price falls as expected, you repurchase the shares at a lower price.
• For example, if you sold at $100 and the price drops to $80, you buy it back at $80.

🔹 4️⃣ Return the Shares and Realize the Profit

• The repurchased shares are returned to the lender.
• The difference between the selling price and the repurchase price becomes your profit.

💡 Example:

• You sell borrowed shares at $100 → Secure $100 in cash
• Stock price falls to $80 → Buy back the shares for $80
• Return the shares → Net profit of $20
• But if the price rises to $120 → You lose $20

📌 Real-World Examples of Short Selling

 

🔹 Institutional Investors Using Short Selling

• Recently, an institutional investor predicted a price drop in a specific stock and executed a large-scale short sale.
• When the stock price actually fell, the investor repurchased the shares at a lower price and secured a profit.

🔹 Short Selling Bans

• From November 6, 2023, to the end of June 2024, South Korean financial authorities banned short selling.
• This wasn’t the first time; during the 2008 Financial Crisis, 2011 European Debt Crisis, and 2020 COVID-19 Crisis, short selling was temporarily restricted to prevent market collapse.
• The goal was to stabilize the market and protect individual investors.

📌 Why is Short Selling Important?

✅ 1. Increases Market Liquidity

• Short selling increases the volume of shares traded, making the market more liquid.
• This added liquidity helps in price discovery and creates more accurate pricing in the market.

✅ 2. Prevents Stock Bubbles

• When a stock is overvalued, short selling helps correct the price.
• It acts as a natural counterbalance to overhyped valuations.

✅ 3. Risk Management Tool

• Institutional investors use short selling as a way to hedge against market downturns.
• It helps reduce losses in a falling market, serving as a protective strategy.

✅ 4. Controversy Over Individual Investor Protection

• When institutions execute large-scale short selling, it can accelerate price declines, harming individual investors.
• This has sparked debates over the fairness of short selling, with some markets even imposing temporary bans.
