Shares of data storage company Western Digital fell nearly 5 percent on Monday after an analyst at Evercore ISI said the market has not fully price the competitive hurdles the company faces.

"The current competitive positioning for WDC is not ideal as we estimate WDC's enterprise SSD (solid state drivers) share has roughly halved in the last few years to ~12%," analyst C.J.
