Fundamentals are important in investing because they provide a method of setting the financial value of a company, currency, and security. Investors and analysts examine these topics to estimate whether the underlying asset is a worthwhile investment and fair valuation in the market. Therefore, for businesses, information such as revenue, profitability, assets, growth potential, and liabilities are fundamentals. Using this analysis, you can calculate a company’s financial ratios to determine the investment’s feasibility.
