Hedge Fund Highlights
One notable move last quarter came from Gotham Asset Management, founded by Joel Greenblatt, which increased its Synopsys position by over 620%, lifting its stake to roughly $15.6 million. The sharp increase suggests it appears the firm became more constructive on Synopsys after previously holding a smaller position.
Aspex Management, led by John Foo, also meaningfully expanded its exposure, increasing its Synopsys stake by about 135% to approximately $749 million. The size of the position suggests the firm may be leaning more confidently into Synopsys’ long term importance within advanced semiconductor design.
Crestwood Advisors Group, founded by Michael Eckton, raised its holdings by roughly 138%, bringing its position to around $660,000. While smaller in dollar terms, the increase suggests it appears Crestwood reassessed its conviction in the stock.
Meanwhile, Balyasny Asset Management, founded by Dmitry Balyasny, boosted its Synopsys position by just over 105%, taking the stake to roughly $6.8 million. The move looks incremental, which may indicate a measured approach rather than a high conviction shift for investors watching hedge fund positioning.

What the Ownership & Insider Trade Data Tell Us
Synopsys’ shareholder base is anchored by large, long term institutions like Vanguard, BlackRock, and State Street, providing a stable ownership foundation. At the same time, selective hedge fund additions suggest some managers appear increasingly comfortable with Synopsys’ strategic position in semiconductor design, even as valuation considerations remain in focus.

For investors, the overall picture suggests Synopsys continues to be treated as a mission critical software platform with durable long term relevance, while both institutions and insiders appear to be taking a measured approach at current price levels.
