Short selling and buying a stock are two opposite investment strategies that involve taking different positions on the future price of a stock. When you buy a stock, you are purchasing a share of ownership in the company, with the expectation that its value will increase over time. You make a profit by selling the stock at a higher price than you paid for it.

On the other hand, short selling involves borrowing shares of a stock from a broker and immediately selling them on the market with the expectation that the stock's price will decrease. If the stock price drops, the short seller can buy the shares back at a lower price and return them to the broker, making a profit on the difference between the sale price and the buyback price.

In summary, buying a stock involves purchasing shares with the expectation that its value will increase, while short selling involves borrowing and selling shares with the expectation that the price will decrease.

Short selling and buying a stock are opposite strategies in trading. Buying a stock, or going long, means you purchase shares with the expectation that their price will rise. You profit when you sell the stock at a higher price than your purchase price.

Short selling, on the other hand, involves borrowing shares from a broker and selling them at the current price, aiming to buy them back later at a lower price. You profit from the price difference if the stock declines.

Short selling is riskier because potential losses are unlimited if the stock price rises instead of falling. Buying a stock limits your loss to your initial investment, while short selling carries greater risk but allows profit from market declines.
