Cadence's IBD composite and EPS ratings of 90 support its standing as arguably the best in the 'making chips better' group after ASML. The screen estimates 2026 EPS growth of 18% and sales growth of 21%. Its chart is near a breakout after a long pullback. x.com 

Cadence Design Systems is the tollbooth of chip design: nobody builds an AI processor without first paying for EDA software, a duopoly market. That shows in 88.9% gross margins and eight straight years of 16–21% EPS growth without a down year. It ranks first and is the highest-conviction name on the software map, with a 96.8 story score, 90.5 chart score and 93.6 composite; with both above 90, the argument is over. The stock sits about 2% from a fresh pivot. x.com  x.com 

Arm's valuation carries an absurd premium for the architecture layer. It trades at 91.9x EV/sales, far above its historical range, as Wall Street prices it as the mandatory royalty tollbooth for every custom AI chip. EDA leaders Cadence, at 30.1x, and Synopsys, at 21.2x, trade near the low end of their historical bands, priced like mature utilities, as the market stacks almost all the scarcity premium into Arm. x.com 

Synopsys is trading at its lowest valuation relative to Cadence in its recent history. It is up just 2% year to date, versus 32% for its closest peer. x.com 

AI should expand Cadence's market as pressure on silicon multiplies the companies designing custom chips, and every chip design startup uses its tools. EDA has risen from 7% to 11% of semiconductor R&D, and Cadence's CEO says AI agents run far more base-tool iterations, lifting usage. Moats are deep, as fabs must certify tools over years. The risk is that its few, highly savvy customers use AI to replace parts of the workflow, and it is tied to chips designed, not to inference spend. x.com 

Cadence and Synopsys are the shovels of the chip boom, controlling 74% of the EDA software every chip design depends on. Customers essentially never leave: switching is costly and risky, software is half of chip design costs and lifetimes exceed 20 years. Revenue is 80-85% recurring with high-80s gross margins and net margins above 20%, and EDA is projected to grow 12-15% a year as end-product makers such as Tesla join chip firms as clients. x.com 

Synopsys looks a bit too cheap at around 20x cash EPS. x.com 

Synopsys merits Overweight and a $650 December 2026 target because EDA's near-permanent switching costs give a durable recurring floor, while emulation and AI-enhanced tools lift growth and margins. Synopsys, Cadence and Siemens EDA control most of the market, and switching toolchains costs engineering years. AI chip design drives emulation hours, and ML tools command a pricing premium. The target is about 40x $16.20 of earnings power exiting 2H CY26; China export controls are the key risk. … Show more
