Thursday brought a trio of analyst upgrades that shifted the outlook for several companies across the tech sector. Here's what Wall Street's top analysts are saying about these stocks.

Synopsys Gets the Nod from BofA

Bank of America Securities analyst Vivek Arya made the biggest move of the day, upgrading Synopsys Inc. (SNPS) from Neutral to Buy. The new price target of $560 represents a meaningful jump from the previous $500 target. Synopsys shares closed Wednesday at $475.83, suggesting the analyst sees roughly 18% upside potential from current levels.

The software design company has become a critical player in the semiconductor industry's infrastructure, and Arya's upgrade signals growing confidence in the company's positioning.

Unity Software Catches BTIG's Eye

BTIG analyst Clark Lampen upgraded Unity Software Inc. (U) from Neutral to Buy, setting a $60 price target on the gaming platform provider. With shares closing Wednesday at $48.98, that target implies solid upside for investors willing to bet on the company's turnaround story.

Unity has been working through strategic shifts after some rocky quarters, and the upgrade suggests analysts are seeing progress in the company's execution.

Soluna Holdings Earns Buy Rating

HC Wainwright analyst Kevin Dede upgraded Soluna Holdings Inc. (SLNH) from Neutral to Buy, announcing a $5 price target. Soluna Holdings closed Wednesday at $1.97, meaning Dede sees potential for shares to more than double if the company hits his target.

The substantial gap between the current price and target reflects either significant opportunity or significant risk, depending on how the company's business develops.

These upgrades represent shifting sentiment from analysts who previously held neutral stances, suggesting new catalysts or improved fundamentals have emerged to justify more bullish positions.
