Memory stocks are clearly one of the core engines of this AI cycle, especially as data center demand keeps scaling faster than supply can adjust.

Names like $SanDisk Corp.(SNDK)$  and $Micron Technology(MU)$ , with their massive YTD performance, highlight how pricing power and tight HBM/DRAM supply are driving the entire sector.

The structural point is straightforward: AI compute growth isn't just about chips, it's about memory bandwidth, and that bottleneck still isn't resolved.

That's why the narrative has expanded from semis in general to a more focused "memory supercycle" theme.

Whether through single names or basket exposure like $Roundhill Memory ETF(DRAM)$ , the trade is essentially the same: positioning around constrained supply in an expanding demand environment.

Still early in the cycle where leadership is consolidating rather than rotating out.
