Investing in stocks requires careful analysis of financial data to find out a company's true worth. However, an easier way to find out about a company's performance is to look at its financial ratios.
Two commonly used financial ratios used in the valuation of stocks are -
Price to Earnings Ratio (P/E) - It compares the company's stock price with its earnings per share. The higher the P/E ratio, the more expensive the stock.
Price to Book Value Ratio (P/BV) - It compares a firm's market capitalization to its book value. A high P/BV indicates markets believe the company's assets to be undervalued and vice versa.
