Synopsys stock closed at USD 367.70 on the Nasdaq on September 15, 2026, down 3.6 percent from the prior session.

September 15, 2026 in numbers
Synopsys Inc. (ISIN US8716071076, Nasdaq: SNPS) shares fell 3.6 percent to close at USD 367.70 on September 15, 2026, after trading between an intraday low near USD 365 and a high around USD 381 on the Nasdaq. A separate intraday report noted that the stock set a new 52-week low during the session, with trades recorded below USD 366 and well under a 52-week high in the USD 530 range, underscoring the recent downside momentum. Market data showed that more than 1,170,000 Synopsys shares changed hands in the session, indicating elevated activity compared with typical daily turnover. In the same trading day, the tech-heavy Nasdaq Composite index also finished in negative territory as United States bond yields climbed and oil prices remained firm, so Synopsys underperformed a weak broader market backdrop by losing 3.6 percent while the Nasdaq decline stayed below 1 percent.
Macro pressures today
Today, investors in Synopsys focus on ongoing macro pressures after major United States equity indexes closed lower on September 15, 2026, as higher Treasury yields and rising energy prices weighed on risk appetite. As Yahoo Finance reported on September 15, 2026, the S&P 500, Nasdaq Composite and Dow Jones Industrial Average all declined as the United States 10-year Treasury yield moved higher, a backdrop that tends to pressure growth and technology valuations. A separate wrap from Pittsburgh Post-Gazette highlighted how rising oil prices and growing expectations for further Federal Reserve tightening added to concerns for rate-sensitive sectors, including high-valuation technology names such as Synopsys. With no company-specific events for Synopsys dated today in public calendars, market attention centers on these macro drivers and on any further moves in United States yields and energy prices that could influence demand for semiconductor and design software stocks into the open.
