Allegro MicroSystems just returned to profitability after a massive increase in data-center income and 125% EPS growth in its last report. The stock is holding a two-month pullback at its 200-day moving average with its lowest MACD reading since the April tariff low, and the chart pattern is bullish on a breakout. x.com  x.com 

STMicroelectronics, onsemi, Texas Instruments and Allegro MicroSystems benefit as AI data center server ramps drive analog demand, offsetting part of continued auto weakness, per an interesting Mizuho note. Mizuho says analog lead times are rising toward 40-42+ weeks with price hikes expected around June and July, and it raised targets on STMicro, onsemi and TI. Per @sean_________ quoting Mizuho, TI plans a second price increase this year, while STMicro and Allegro raised prices about 10%. x.com 

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 

STMicroelectronics offers rare asymmetry for a large cap: a bear case in line with the S&P 500, a slightly better base case and a wildly better bull case. 2026 marked an inflection in its data-center business, with a multi-year, multi-billion-dollar Amazon agreement and guidance raised from $1B before 2030 to well above $2B in 2027. A base case with a modest AI business implies 15% annual growth through 2030; if photonics, power and robotics reach a third of revenue, 30-50%. x.com  x.com  x.com 

Allegro MicroSystems is the best way to own the sensing behind scalable humanoid actuators, where the humanoid race will be won. A humanoid has about 43 actuators, each needing current sensing for torque control, where Allegro's magnetic current sensor ICs lead with automotive-grade credentials. Its semiconductor economics scale cheaply: 1M humanoids a year means over 43M sensor ICs on existing fabs. Vishay Precision offers purer force sensing but trades at high multiples with harder scaling. … Show more

NVE's spintronic sensors are locked into products that cannot requalify a second source. Once one is designed into a pacemaker or defense module, swapping it means redoing the whole safety qualification, and couplers carry 40-plus-week lead times once a design is locked. Revenue grew 81% year over year last quarter on $31M trailing, with 79% gross and 66% operating margins, net cash and a 0.84 PEG. The risk: at $486M and 14.9x EV/sales, growth must repeat against a brutal comparison next year. … Show more

Vishay Precision Group is a pick-and-shovel play on humanoid robots, which need large volumes of strain gages and precision torque sensors where VPG is a global technology leader. It is already in the pre-production supply chains of four humanoid developers, and management expects its robot revenue, $4 million in 2025, to compound 50% a year. Its bulk metal foil resistors are essential to AI chip test equipment and server boards, and Q1 brought record defense resistor orders. x.com 

Navitas Semiconductor's GaN chips address the power bottleneck in AI data centers, where rising GPU power draw has pushed silicon power chips to their physical limits. Its CEO puts GaN's design value at $10,000-$15,000 per MW, and high-power market revenue rose 35% year over year in Q1. After a brutal 2025 of weak consumer demand, dilution and losses, the Navitas 2.0 pivot and Q1's return to sequential growth suggest the worst is over, with its AI power line moving into system validation. 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 

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
