NEW YORK, December 29, 2025, 21:23 ET — Market closed
- Synopsys shares rose 0.4% to $478.97 on Monday, outperforming a softer Nasdaq session.
- Investor-law firms flagged a Dec. 30 deadline tied to a securities class-action case involving Synopsys.
- Markets’ next test is Tuesday’s Fed minutes and key U.S. data in thin year-end trading.
Synopsys shares ended Monday up 0.4% at $478.97, holding gains into the close even as broader U.S. stocks slipped in holiday-thinned trading.
The chip-design software maker is closely watched because its electronic design automation (EDA) tools—software used to design and test chips—sit early in the semiconductor supply chain and tend to reflect demand for next-generation computing.
The timing matters. U.S. markets are heading into the final days of the year with light liquidity, while investors await the Federal Reserve’s December meeting minutes on Tuesday for clues on the 2026 rate path.
Synopsys traded between $471.28 and $484.33 during the session, with about 1.33 million shares changing hands, according to market data.
The stock outperformed parts of the tech complex. The Invesco QQQ Trust—an ETF tracking the Nasdaq-100—fell 0.5% on the day, while the iShares Semiconductor ETF was slightly lower.
In the EDA group, rival Cadence Design Systems slipped about 0.4%, while Nvidia—one of Synopsys’ key partners and a bellwether for AI-linked spending—fell about 1.2%.
Company-specific headlines were limited, but several investor-law firms circulated reminders on Monday about a securities class-action lawsuit and a Dec. 30 deadline for investors seeking to be appointed lead plaintiff. In one notice, Levi & Korsinsky said the complaint concerns alleged misstatements tied to the company’s Design IP business and related economics.
Synopsys has faced heightened scrutiny since a sharp selloff earlier this year. In September, the company’s shares sank after the company disclosed a quarterly revenue miss and warned about China-related pressures, Reuters reported at the time.
Investors have largely shifted focus back to execution and guidance. Synopsys said on Dec. 10 it expects fiscal 2026 revenue of about $9.61 billion at the midpoint, including roughly $2.9 billion of expected Ansys revenue, and forecast first-quarter revenue of $2.365 billion to $2.415 billion for the period ending Jan. 31, 2026.
“The Synopsys team delivered a solid finish to a year that redefined our company as the leader in engineering solutions from silicon to systems,” CEO Sassine Ghazi said in the company’s December results statement. Synopsys Investor Relations
Before Tuesday’s session, traders will watch U.S. data on home prices and business activity, followed by the Fed minutes at 2:00 p.m. ET—events that can sway rate expectations and, by extension, valuations for growth stocks such as software and chip-design names.
The near-term tape has clear markers. A break below Monday’s low near $471 would put the late-December rebound under pressure, while a push back through the $484 area would leave the stock testing recent resistance. Beyond the next session, investors are likely to focus on any updates tied to litigation headlines and Synopsys’ ability to meet its first-quarter targets as it integrates Ansys and navigates export-control assumptions embedded in its outlook.
