What are the best metrics to research a company stock for investment?

​There are many metrics that can help you research a company stock for investment, but some of the most common and useful ones are:
 
• Price-to-earnings ratio (P/E ratio): This metric compares a company's current price to its per-share earnings. It shows how much the market is willing to pay for a stock based on its past or future earnings. A low P/E ratio may indicate that a stock is undervalued or has strong growth prospects, while a high P/E ratio may indicate that a stock is overvalued or has weak growth prospects 

​• Price-to-book ratio (P/B ratio): This metric compares a company's market value to its net assets. It shows how much investors are paying for a company's assets relative to their book value. A low P/B ratio may indicate that a stock is undervalued or has a strong balance sheet, while a high P/B ratio may indicate that a stock is overvalued or has a weak balance sheet

• Debt-to-equity ratio (D/E ratio): This metric measures a company's financial leverage. It shows how much debt a company has relative to its equity. A low D/E ratio may indicate that a company has a low risk of default and a high financial stability, while a high D/E ratio may indicate that a company has a high risk of default and a low financial stability

• Price/earnings-to-growth ratio (PEG ratio): This metric adjusts the P/E ratio for the expected growth rate of a company's earnings. It shows how much the market is paying for a stock relative to its earnings growth potential. A low PEG ratio may indicate that a stock is undervalued or has a high growth rate, while a high PEG ratio may indicate that a stock is overvalued or has a low growth rate

• Dividend yield: This metric measures the amount of cash dividends paid by a company to its shareholders relative to its share price. It shows how much income investors can expect from holding a stock. A high dividend yield may indicate that a stock is undervalued or has a strong cash flow, while a low dividend yield may indicate that a stock is overvalued or has a weak cash flow
