Alpha and Omega Semiconductor's pivot to AI data-center power is gaining traction beneath muted overall revenue. AI-focused power delivery in its advanced computing division grew over 40% year over year and doubled sequentially, and CEO Stephen Chang reports rising demand from hyperscalers and supercomputing operators. High-margin power ICs grew 30% to nearly 40% of product sales. Insider selling and valuation froth may cause volatility, and second-half results need to validate AI growth. x.com 

Intel's data-center and foundry growth could outlast its PC-driven weak guidance. Data-center revenue rose 78% to $7.3bn and foundry revenue rose 58%, but PCs still account for about half the business and management expects their slowdown through at least the first half of next year. Q4 revenue and margin guidance disappointed, and $0.17 of quarterly EPS came from a mark-to-market gain. The selloff prices in the PC problem, not the turnaround. Overweight; $130 target. x.com  x.com 

Alpha and Omega Semiconductor is a promising business at the wrong price: its rerating on Nvidia AI-power hype rests on a narrative management has already walked down. The stock is up about 128% in a year to $44.45, near its 52-week high, as retail frames it as the cheapest catch-up in the 48V-to-12V power shift, citing alleged Nvidia GB300 DrMOS allocation. Yet the 800V supply chain is hard to win, with its bottleneck in silicon carbide and gallium nitride held by a few incumbents. x.com  x.com  … Show more

Navitas, Alpha and Omega, Power Integrations, Wolfspeed and Vicor are all that is needed for the power-semiconductor trade, which @aleabitoreddit ties to NVIDIA's push to 800 VDC. Navitas makes next-generation AI power chips, Alpha and Omega AI and EV power chips, Power Integrations efficient power-conversion chips, Wolfspeed silicon-carbide power chips, and Vicor high-density AI power modules. x.com 

Onsemi's AI data center business is no longer a side story: revenue there is now expected to more than double in 2026, with growth across the whole power tree. Management is shifting capacity from autos to AI, utilization rose from 77% to 83% with most of the margin benefit due in Q4 and 2027, a second round of price increases is holding, and lead times stretched to 32 weeks with visibility into 2027-2028. Content per rack is projected to rise from about $15k today to $115k by 2030. x.com 

onsemi's inventory correction is ending while its AI data center business surges, yet the stock is about 46% below its June 3 high. Distribution inventory fell to 10.1 weeks, fab utilization rose to 83% and lead times stretched from 27 to 32 weeks. The company expects AI data center revenue to more than double in 2026, and management targets another doubling in 2027. onsemi says power content per AI rack can rise from about $15,000 to roughly $115,000 as racks move to high-voltage designs. x.com  … Show more

Magnachip's Q1 showed solid progress that still lost out to overheated sentiment, confirming the warning that merely meeting expectations wouldn't sustain April's momentum. Gross margin rose to 15.6% from 9.3%, the top of guidance, and inventory days fell to 77, suggesting genuine server MOSFET demand. But planned Fab 3 downtime in the second half and conservative Q2 guidance limit near-term growth. With $94.6M of cash against a $135M valuation, it must win AI-server power before the cash thins. … Show more

AI bottleneck semiconductor stocks look to have gotten ahead of themselves, with roughly a hundred near-vertical charts where downside now seems to outweigh upside. They are semis and highly cyclical, and many smaller caps may end up trading like meme stocks. A substantial shakeout would offer a better entry. AI, robotics and energy still have years of growth ahead, but chasing these names now is not advisable. x.com  x.com  x.com  x.com  x.com
