Evaluating a stock before investing is crucial for making informed decisions and building a successful portfolio. Investors use a range of financial metrics to assess a company’s performance, profitability, valuation, and risk. Here are some of the most important metrics to understand and apply when analyzing stocks.
1. Price-to-Earnings (P/E) Ratio
This ratio compares a company’s stock price to its earnings per share (EPS).
Formula: Stock Price ÷ EPS
A high P/E may indicate overvaluation or high growth expectations.
A low P/E might suggest undervaluation or weak future prospects.
2. Earnings Per Share (EPS)
EPS shows how much profit a company generates per outstanding share.
Formula: Net Income ÷ Number of Shares
Growing EPS typically signals increasing profitability.
3. Price-to-Book (P/B) Ratio
The P/B ratio compares the market value of a company to its book value.
Formula: Share Price ÷ Book Value Per Share
A P/B under 1 may indicate undervaluation, especially in asset-heavy industries.
4. Return on Equity (ROE)
ROE measures how effectively management is using shareholders’ equity.
Formula: Net Income ÷ Shareholders’ Equity
A higher ROE suggests efficient capital use.
5. Dividend Yield
This ratio shows the annual dividend payment as a percentage of the stock price.
Formula: Annual Dividend ÷ Stock Price
Useful for income-focused investors seeking regular returns.
6. Debt-to-Equity Ratio (D/E)
This metric gauges a company’s financial leverage.
Formula: Total Liabilities ÷ Shareholders’ Equity
A high ratio may signal financial risk or aggressive growth financing.
7. Free Cash Flow (FCF)
FCF represents the cash a company generates after capital expenditures.
Formula: Operating Cash Flow – Capital Expenditures
Positive and growing FCF indicates strong financial health.
8. Current Ratio
This ratio measures short-term liquidity.
Formula: Current Assets ÷ Current Liabilities
A ratio above 1 suggests the company can meet short-term obligations.
9. Revenue Growth
Consistent revenue growth reflects an expanding business and can lead to higher profits over time. It is particularly important for growth companies.
10. PEG Ratio (Price/Earnings to Growth)
This ratio adjusts the P/E ratio for a company’s expected earnings growth.
Formula: P/E ÷ Annual EPS Growth Rate
A PEG below 1 may suggest the stock is undervalued relative to growth.
Qualitative Factors to Consider
Industry Position: Is the company a market leader or a newcomer?
Competitive Advantage: Does it have a strong brand, patents, or network effect?
Management Quality: Experienced, shareholder-friendly leadership is a positive signal.
Economic Moat: Sustainable advantages that protect long-term profits.

By applying these metrics consistently, investors can make better decisions and improve their chances of long-term success in the stock market.
