I've been building positions around three core themes for a while now: Neoclouds, Photonics, and Memory.
It's interesting to see how these themes are starting to play out across names like $Applied Optoelectronics(AAOI)$ , $iShares MSCI South Korea ETF(EWY)$ , and NBIS. The rotation feels more theme-driven than single-stock driven at this point.
Even some of the risk assessments have played out—$IREN Ltd(IREN)$ is still dealing with constant ATM supply pressure (around a $6B overhang), while $NEBIUS(NBIS)$ pushes to new highs. That divergence says a lot about positioning versus narrative.
Ultimately, it's not just about picking a stock—it's about identifying the next dominant theme, then concentrating into the winners.
If you were early in software but picked the wrong leader, you still underperformed the real compounders. The same idea applies here.
Photonics still feels early. Nebius could evolve into an AWS-style infrastructure layer over time. And $Micron Technology(MU)$ / SK Hynix / Samsung… if memory demand stays structural, they stop trading like cyclicals and start trading like infrastructure.
Themes matter more than entry points.
