Western Digital surged nearly 16% today, outpacing Micron's 6% gain. The move follows reports that DRAM prices are spiking due to AI demand. While WDC focuses on hard drives rather than DRAM, the thinking is that expensive memory will push demand toward cheaper HDD alternatives. Looking at valuations, WDC is trading at 26x earnings with a PEG of 1.2. Micron looks relatively cheaper fundamentally with a PEG of 0.6, thanks to higher projected growth rates despite a higher P/E multiple.
