description: "🚀 Up about 400% since the public sharing: No genius needed, just bet on the right "bottleneck"To be honest, this isn't about predicting the macro, nor is it about god-level stock picking.Most of it comes from two factors:Choosing the right track.Following the flow of capital.Plus a bit of luck.The real money-making logic this year: Bet on "bottlenecks," not on storiesThe core framework this year is simple:Where are the physical bottlenecks for AI expansion?That's where the money will pile up.My current favorite categories:1️⃣ Memory$Sandisk(SNDK.US)$Micron Tech(MU.US)$Silicon Motion Tech(SIMO.US)Samsung, SK HynixWhen computing power explodes, HBM, DRAM, NAND aren't optional; they're necessities.Computing power can be scaled,but if memory can't keep up, the system grinds to a halt.This is the bottleneck premium.2️⃣ Photonics / Optical Modules$Lumentum(LITE.US)$Coherent Corp.(COHR.US)$Applied Optoelectronics(AAOI.US)$AXT(AXTI.US)When data centers enter GW-level expansion,the "connection speed" between computing units becomes the core issue.Powerful GPUs are uselessif optical interconnects can't keep up; latency is the Achilles' heel.3️⃣ Power / Grid$XLUComputing power is an energy monster.Every round of data center expansionpassively benefits the power grid and utilities.AI is a digital revolution,but its foundation is an energy revolution.4️⃣ Advanced Packaging Capex$Amkor Tech(AMKR.US)$Onto Innovation(ONTO.US)$Camtek(CAMT.US)$Kulicke and Soffa(KLIC.US)$Formfactor(FORM.US)HBM, Chiplet, advanced packagingare the last mile for computing power to truly materialize.Many people watch $NVIDIA(NVDA.US),but the real capacity choke point is the packaging stage.Why are these up 50%-100%+?Because they aren't sentiment sectors.They are physical constraints.When demand explodes,bottleneck assets naturally gain pricing power.This greatly amplifies trading gains.The most important lesson I learned this yearDon't try "reverse rescues."For example:Betting on a cybersecurity reversalBetting on SaaS recoveryBetting on a sentiment bottomWhere is the market's money?Where is it most scarce?Following the flow is more important than being smart.What really changed my profit curve wasn't correctly predicting the future.It was constantly asking one question:Where is the next place that will get stuck?Because capital always rewards the bottleneck first.By the time everyone sees it,half the profit has already been eaten."
