PEG RATIO

Summary

The PEG ratio is a valuation metric that helps investors determine whether a stock is fairly priced by comparing its price-to-earnings ratio to its expected earnings growth rate. It's calculated by dividing the P/E ratio by the annual earnings growth rate (expressed as a percentage). A PEG ratio of 1.0 suggests the stock is fairly valued, below 1.0 may indicate undervaluation, and above 1.0 might suggest overvaluation. This metric is particularly useful because it accounts for growth prospects, making it more comprehensive than using P/E ratio alone.

Usage Context

Essential when learning about stock valuation methods, comparing investment opportunities, analyzing growth stocks versus value stocks, and understanding how growth expectations affect stock pricing in equity analysis and portfolio management.

Common Confusions

• Thinking that a lower PEG ratio is always better without considering the quality of growth estimates
• Using PEG ratios to compare companies in very different industries
• Forgetting that PEG ratios are only as reliable as the growth projections used
• Assuming the PEG ratio works well for mature, slow-growth companies
• Misunderstanding that negative earnings growth makes PEG ratio meaningless
