Another View On JAPAN POST BANK's Valuation

The first story frames JAPAN POST BANK as undervalued against a fair value estimate, but the earnings multiple paints a different picture. The stock trades on a P/E of 19.9x versus a JP Banks industry average of 15.3x, and a fair ratio of 20.8x that the market could move toward.
