PEG = Price/Earnings to Growth ratio

What is the PEG ratio

The PEG ratio (Price/Earnings to Growth ratio) is a financial metric that compares a company's P/E ratio with the pace at which its earnings are growing. It is used to determine whether a stock is overvalued, undervalued, or fairly valued given expected growth.

How the PEG ratio is interpreted

• PEG = 1 – the stock is considered fairly valued relative to growth.
• PEG < 1 – may indicate that the stock is undervalued.
• PEG > 1 – may suggest overvaluation or very high market expectations.

Factors that influence the PEG ratio

• Earnings growth estimates – a key input of the calculation that can be inaccurate.
• Sector differences – growth sectors tend to have a higher PEG, defensive sectors a lower one.
• Macroeconomic conditions – changes in interest rates or inflation can affect growth estimates.

Advantages and limitations of the PEG ratio

Advantages:

• Better than the P/E ratio alone at taking a company's growth potential into account.
• Enables comparison of companies across different industries.

Limitations:

• Depends on the accuracy of growth estimates.
• Can be misleading for companies with volatile earnings.
• Not suitable for companies with negative earnings.
