TTM Technologies is the top defense and AI PCB pick, central to AI hardware yet trading at 20.3x forward earnings versus a 25.6x median for Asian rivals. It just posted its first $1B revenue quarter at record margins, holds over 40% share on Nvidia's VR200 platform and is qualified on nearly every major AI accelerator. PCB content rises from $35k in GB300 to $116k in VR200 as layer counts climb. The CEO and a board member bought $1.6M of stock, the first insider buying after months of selling. … Show more

Insiders are buying TTM Technologies 17% below its highs, supporting the case that its AI circuit-board bottleneck is underpriced. The CEO put $1.1 million into the stock, a day after a director bought $525K. Nvidia GPU boards use over 30 layers and the next generation needs 50 to 100+. TTM is the only US-listed pure-play PCB maker, called a top-five qualified supplier by an Nvidia account manager, yet trades at 20x forward earnings against 25x for Asian competitors. x.com 

TTM Technologies, Rogers and Murata Manufacturing are among the component names on a list of potential losers, though TTM may still work as a shorter-term long trade into earnings. x.com 

TTM Technologies' data center and networking business is growing fast enough to become half or more of the company, a shift expected eventually but that showed up in a single quarter. Its end markets are strong, including circuit boards for TPUs and aerospace and defense. The stock is probably getting a little extended here. x.com 

TTM Technologies benefits from rising printed circuit board prices, a fit for what is clearly a stock picker's market. x.com 

TTM Technologies is a re-rating gem. x.com 

Companies highly correlated with TPU capital spending, Broadcom, MediaTek, Lumentum, Semtech and TTM Technologies, should all keep going up; embrace the bubble. x.com 

Low multiples give AI infrastructure good risk/reward as demand outruns supply and agentic workloads have runway. TSMC at 17x 2027E EPS appears to have all the accelerator and CPU demand it can handle this year and next; Ultra Clean is at 8x, MKS 12x, TTM 13x, Nvidia 14x and Celestica 15x. Kioxia at 3x and Samsung preferreds at 2.5x carry a big discount on pricing and cycle fears. Multiples imply a 2027 capex peak and meaningful drop; 2028 capex growth is expected, but below 2027's rate. x.com  … Show more

AI infrastructure bottlenecks could give eight stocks as much as 18x upside. Nvidia supplies frontier-model GPUs; Broadcom and Marvell supply custom silicon and networking; TSMC makes advanced chips; Micron supplies sold-out HBM; Vertiv provides power and cooling; Palantir monetizes enterprise AI; Alphabet spans TPUs, research, cloud and apps. The list tracks where AI infrastructure spending is flowing. x.com  x.com 

TSMC's strong AI demand is straining supply, while solid company fundamentals and attractive semiconductor valuations make an abrupt stop to its advance unlikely. TSMC's Wendell Huang expects 2026-28 capex to be significantly higher than in the previous three years to support customer growth; he says most capex is tied to long-term demand. x.com
