This article highlights the performances of each of the 6 AI sub-segment portfolios and that of their constituents in 2025. ### **The Sub-segment Portfolios In Our Model AI Semiconductor Portfolio** _The first 4 of the 6 sub-portfolios consists of those categories that account for the 4 specific steps in the manufacturing of semiconductors, namely:_ 1. _**The design of complex semiconductor chips** using sophisticated electronic design automation (EDA) software,_ i.e. Our Model Pure-Play EDA Software Chip Design Stocks Portfolio; 2. _**The supply of equipment and material** necessary to build and operate a semiconductor foundry,_ i.e., Our Model Pure-Play Semiconductor Supplier Stocks Portfolio; 3. _**The foundries that fabricate the chips** based on the designs provided by other semiconductor companies,_ i.e. Our Model Pure-Play Semiconductor Foundry Stocks Portfolio; and 4. _**The companies that assemble chips into finished semiconductor components, test for defects, and provide the specialized packaging** necessary for shipping the chips around the world,_ i.e., Our Model Pure-Play Outsourced Semiconductor Assembly & Test Stocks Portfolio. _The other two categories are those major companies that:_ 1. _**Design and sell hardware devices and semiconductor chips themselves while outsourcing their fabrication** (i.e., are fabless) to a specialized manufacturer;_ i.e., Our Model Pure-Play Fabless Semiconductor Stocks Portfolio; and 2. _**Do everything themselves in-house** to control the entire production process from beginning to end,_ i.e., Our Model Integrated Device Manufacturer Stocks Portfolio. ### **The Performance In 2025 Of Each Sub-segment Portfolio** 5 of the 6 portfolios advanced in 2025 with only our model _Pure-Play_ EDA Software Chip Design Stocks Portfolio declining fractionally (DOWN 0.4%). The average increase of the 6 portfolios was 45.3% and below are their performances, in descending order, along with that of their constituents: 1. **Our Model _Pure-Play_ Semiconductor Supplier Stocks Portfolio: UP 74.1% in 2025** - **Constituent Returns:** - **Lam Research (LRCX): + 137.0%;** KLAC Corp. (KLAC): +92.8%; Applied Materials (AMAT): +58.0%; ASML Holding (ASML): +54.4% 2. **Our Model _Pure-Play_ Semiconductor Foundry Stocks Portfolio: UP 55.5% in 2025** - **Constituent Returns:** - **Tower Semiconductor (TSEM): +128.0%;** Taiwan Semiconductor (TSM): +53.9%; United Microelectronics (UMC): +21.1%; **GlobalFoundries (GFS): DOWN 18.6%** 3. **Our Model _Pure-Play_ Outsourced Semiconductor Assembly & Test Stocks Portfolio: UP 55.4% in 2025** - **Constituent Returns:** - **ASE Technology (ASX): +59.9%;** Amkor Technology (AMKR): +53.7% 4. **Our Model _Pure-Play_ Fabless Semiconductor Stocks Portfolio: UP 42.2% in 2025** - **Constituent Returns:** - **Advanced Micro Devices (AMD): +77.9%;** Monolithic Power (MPWR): +55.8%; Broadcom (AVGO): +49.3%; Nvidia (NVDA): +39.0%; Qualcomm (QCOM): +11.3%; **Marvell (MRVL): DOWN 23.1%** 5. **Our Model _Integrated_ Device Manufacturer (IDM) Stocks Portfolio: UP 35.2%** - **Constituent Returns:** - **Micron Technology (MU):+239.1%;** Intel (INTC): +84.0%; Infineon Technologies (IFNNY): +35.6%; Analog Devices (ADI): +27.7%; Microchip Technology (MCHP): +11.1%; NXP (NXPI): +4.4%; STMicroelectronics (STM): +4.1%; **Texas Instruments (TXN): DOWN 7.5%** 6. **Our Model _Pure-Play_ EDA Software Chip Design Stocks Portfolio: DOWN 0.4% in 2025** - **Constituent Returns:** - **Cadence Design Systems (CDNS): +4.0%; Synopsys (SNPS): DOWN 3.2%** ### **Summary** **The 6 sub-segment portfolios in our model AI Semiconductor Stocks Portfolio were UP 45.3%, on average, in 2025**, while the Nasdaq (QQQ) was only UP 20.2%. ### _**Addendum**_ _The Portfolio is not tradable but if you are interested in investing in this sector check out the VanEck Semiconductor ETF (SMH) which has 26 holdings (almost identical to our **mo**del AI Semiconductor Stocks Portfolio) and it was UP 48.7% in 2025._ * * * _More By This Author:_ AI Semiconductor Stocks Portfolio Was Up 45% In 2025 - Take A Look Our Model AI Hardware Semiconductor Stocks Portfolio Is The Backbone Of The AI Revolution - Take A Look What Bubble?
