Text: Western Digital stock price dropped 30% from around $63 at 2019 end, to almost $45 currently, primarily due to unfavorable changes in its P/S multiple. This comes as a surprise, as the company has witnessed a rise in revenue over this period, and revenue per share has risen, despite a 6% increase.
