For which of the following firms is the Price/Earnings to Growth (PEG) ratio most appropriate for identifying undervalued or overvalued equities? Firm A: Expected dividend growth = 6%; Cost of equity = 12%; price-to-earnings (P/E) = 12. Firm B: Expected dividend growth = ?6%; Cost of equity = 12%; price-to-earnings (P/E) = 12. Firm C: Expected dividend growth = 1%; Cost of equity = 12%; price-to-earnings (P/E) = 12.
The formula for the PEG ratio is: PEG = (P/E) / g. It measures the tradeoff between P/E and expected dividend growth (g). For traditional growth firms, PEG ratios fall between 1 and 2. The general rule is that PEG ratios above 2 are indicative of overvalued firms (expensive), and PEG ratios below 1 are indicative of firms that are undervalued (cheap).
Firm A: |
PEG = 2, indicating a stock that is appropriately priced. |
Firm B: |
The PEG ratio of firms with negative expected dividend growth is negative, which is meaningless. For Firm B, PEG = -2. |
Firm C: |
Firms with very low expected dividend growth are likely to have PEG ratios that unrealistically indicate overvalued stocks. For Firm C, PEG = 12. | |
