Price/Earnings to Growth (PEG) Ratio

The PEG ratio builds on the P/E by factoring in a company's growth potential to gauge valuation more accurately. It calculates by dividing the price-to-earnings ratio by the expected annual earnings growth rate, expressed as a percentage. This metric helps identify stocks that might be undervalued relative to their future earnings trajectory. A balanced PEG indicates fair pricing for the anticipated expansion.

Investors typically seek PEG ratios below 1.0, signaling that the stock's price aligns well with or undercuts its growth prospects. For high-growth sectors like technology, a PEG around 1.5 might still represent value, while anything above 2.0 often suggests overvaluation. Compare PEG across peers in the same industry to spot relative bargains. Remember to verify the growth rate's source, as optimistic projections can inflate the appeal of otherwise pricey stocks. This approach refines basic P/E screening for more nuanced decisions.

Consider a software company trading at a P/E of 24 with analysts projecting 30% annual earnings growth over the next five years. Its PEG ratio comes out to 0.8, hinting at potential undervaluation. In contrast, a retailer with a P/E of 18 but only 10% expected growth yields a PEG of 1.8, which may deter growth-focused buyers.
