10 Biggest Companies in the World by Market Cap

10 Biggest Companies in the World by Market Cap

A company's Market Capital is the reflection of a company's worth in the real world. To be precise, a market cap is the company's total value of shares of stocks. Market capital sometimes referred to as “Market Cap” is used to calculate the value of the company. It is calculated by multiplying the current share price with the total outstanding shares. For example, if a company's current share price is 5 dollars with 500 million outstanding shares, its market cap would be $5 Billion.

It is worth noting that a huge market cap is not related to the company's revenue and earning potential. A large-cap company may not generate equal or more revenue than a mid-cap or other large-cap company. For example, as of 2023, Apple is the most valuable company with a market cap of $2.951 T. However, it reports fewer revenue figures than Walmart, which reports the most revenue out of any other company in the USA (638.78 B). Furthermore, if we compare Walmart's competitor Amazon, which is also one of the largest companies in the world, Walmart posts better revenue figures. Also, to give you a clearer picture, Walmart is not in the top 10 list of the world's most valuable companies.

Therefore, it is true to say that the market cap represents a company's worth in an open market along with the company's size. Similarly, it also shows the future prospects as it reflects what investors are ready to pay for its stocks. Even with low revenue figures, some companies found their place in the top 10 list due to the staggering market cap, which is a result of optimism shown by investors in potential growth. So, let’s find out some of the largest market cap companies in the world.

Frequently Asked Questions (FAQs)

Q.1 Why companies are ranked by market cap?

Companies are ranked according to their respective market cap because a company's market cap is equal to the value of share price and total outstanding shares. It is taken into account as the share price itself is affected by other parameters such as revenue, growth, CAGR, promoter holding, etc. Also, the market cap shows the size of a company, which helps make judgments.

Q.2 What is the relationship between market cap and stock price?

The stock price is not affected by the market cap but the other way around. The stock price is one of the parameters in the calculation of market cap. It is calculated by multiplying total outstanding shares (Held by investors + held by promoters and insiders) and the current share price of the market. So when the stock price of a company rises, its market cap increases.

Q.3 Does a higher market cap mean a bigger company?

The market cap allows investors to understand the size of the company in the respective sector. Because it is a mixture of share price and total shares, it represents the overall company’s dimension. And, therefore, the higher the market cap, the bigger the company in general.
