PEG ratio definition


Price/earnings to growth (PEG ratio) show the proportion between two ratios. P/E ratio (amount of net income per one share) is divided by ESP (earnings per share) growth. As ESP growth is taken into calculations, this ratio is used as an indicator of the potential market value of the company. Data needed to calculate this ratio is collected from income statement and stock market bulletin.

This ratio is important for the company’s investors (especially while evaluating the company’s possible market value in future), because it helps to consider whether the evaluated shares are overpriced or underpriced.
