PEG ratio API

PEG ratio = (P/E) / (earnings growth % per year), normalizing the P/E by growth, with a valuation bucket (PEG<1 potentially undervalued, <=1.5 fairly valued, else potentially overvalued). Answers 'is this P/E justified by growth','PEG ratio of 20x at 25% growth','growth-adjusted valuation'.
