Serenity(@aleabitoreddit):I'm not having a fun day since I got sick today. But the bottlenecks are having a good time: $AMD +9.13% | $INTC +14.16% | $ARM +14.33% CPUs go brrr $SIVE +10.32% | $AAOI +3.39% | AMS OSRAM +24.61% Lasers go brrr $EWY +4.08% | $DRAM +2.83% | $MU +2.23% Memory go brrr $NBIS +4.7% | $CRWV +5.03% | $IREN +1.73% Compute go brrr Probably most material developments were CPU:GPU ratio expectations + CPU demand (from new AI releases). As well as optical developments from ECOC 2026 (as seen with $MRVL PR + others) Still a lot to catch up on.

The main duo $SKHY and Samsung are having a fun day. I'm still long memory (eg. $EWY / $DRAM ) since if capacity agreements extend 3-5 years... and your analysts model 2.8-3.3x 2027E. Risk/reward is attractive over time. But I think legacy memory a very interesting trade currently due to ASP hike potential.. It also just so happens these same companies procure memory from even smaller memory companies (that might have higher sensitivity)... So if you want to, you can track $PSMC wafer allocations, and find some interesting companies that likely replace $MU discontinued legacy memory through Alliance or supply directly to Samsung. Won't mention them on X, but just throwing out some research ideas.
