Another angle on value

This $321 fair value story exists alongside a different message than the numbers. Western Digital’s P/E ratio of 23.7x is higher than its peer group’s 21.4x and Global Tech’s overall average of 21.9x, but below the 40.1x P/E ratio that the market should aim for.

Does this price simply reflect momentum and recent strong performance? Or does the difference with the higher fair ratio suggest there is room for further execution if earnings hold up? In any case, what needs to change in the story for the market to revalue the multiple?
