@kerrym1971 P/E only works for companies with similar growth rates
PEG adjusts for the growth rate and allows you to compare. All it says is basically a company growing earnings with 50% earnings growth that trades at 50 P/E is as fairly valued as a company with 10% earnings growth rate and 10 P/E. PEG just illustrates that higher growth rates justify higher P/E multiples and that if you have a high P/E multiple on a stock, you also need to have a high growth rate. The whole point of the ratio is to allow for different growth rates in the comparison
