Introduction

Investing in the stock market can be a lucrative way to grow your wealth, but it also comes with risks. One of the key aspects of investing in stocks is understanding the concept of gain or loss. In this article, we will explore how to calculate the gain or loss on an investment, using a real-life example of an investor who purchased 50 shares of stock in a company.

The Purchase

The investor purchased 50 shares of stock in a company for $\$2,100$ , with an additional $\$8$ commission. This means that the total cost of the investment was $\$2,108$ . The purchase price per share can be calculated by dividing the total cost by the number of shares:

$\$2,108$ ÷ 50 shares = $\$42$ per share

The Sale

Later, all of the stock was sold at $\$38$ per share. To calculate the total revenue from the sale, we multiply the sale price per share by the number of shares:

50 shares × $\$38$ per share = $\$1,900$

Calculating the Gain or Loss

To determine whether the investment resulted in a gain or loss, we need to compare the total revenue from the sale to the total cost of the investment. If the total revenue is greater than the total cost, then the investment resulted in a gain. If the total revenue is less than the total cost, then the investment resulted in a loss.

In this case, the total revenue from the sale is $\$1,900$ , which is less than the total cost of the investment, $\$2,108$ . Therefore, the investment resulted in a loss.

Calculating the Loss

To calculate the amount of the loss, we subtract the total revenue from the sale from the total cost of the investment:

$\$2,108$ (total cost) - $\$1,900$ (total revenue) = $\$208$ loss

Conclusion

In conclusion, the investor's investment in 50 shares of stock resulted in a loss of $\$208$ . This is because the total revenue from the sale was less than the total cost of the investment. Understanding how to calculate gain or loss is an essential aspect of investing in the stock market, and it can help investors make informed decisions about their investments.
