PEG Ratio is a valuation metric for determining the relative trade-off between the price of a stock, the earnings per share (EPS), and the company’s trailing EPS growth rate. A lower ratio is considered ‘better’ (cheaper)
and a higher ratio is ‘worse’ (expensive).
PEG Ratio = (P/E Ratio) / Trailing EPS Growth Rate*
*Note, the growth rate is multiplied by 100 before this calculation.
Applying this formula, Phathom Pharmaceuticals’s PEG Ratio is calculated below:
