Memory stocks are surging irrationally; here is my analysis after reviewing earnings reports

My clients have been a bit anxious these past few days. They're looking at procurement budgets for AI infrastructure, seeing Micron up roughly 715% YoY and SanDisk up 653%, and asking me if it's still viable to follow this market trend. Coincidentally, I started closely tracking SK Hynix's capacity data last month, so I pulled the earnings reports of the top four manufacturers and did a horizontal comparison.
