Subject: Re: Vanguard ETF stats
PE is listed as 24.7, but PB 4.3 / RoE 24.61% comes to 15. Am I making some elementary calculation mistake here?

P/E = Price per share / earnings per share

P/B = Price per share / book value per share

RoE = Return on Equity

The P/E ratio has nothing to do with the P/B to RoE ratio.
