Notable movers

ACV Auctions Inc. (ACVA) +44.18%

Copart agreed to acquire ACV for $10.50 per share in cash, implying an equity value of approximately $1.9 billion. The session's standout eligible merger-arbitrage move, with more than 115 million shares traded and the close pinned just below the cash offer.

Frequency Electronics, Inc. (FEIM) +42.41%

Fiscal first-quarter revenue reached a company-record $23.5 million, up 70% year over year, while funded backlog rose 82% to a record $129 million and operating margin exceeded 22%. A rare post-earnings revaluation large enough to push the aerospace-and-defense electronics supplier above the eligibility threshold on heavy volume.

NuScale Power Corporation (SMR) -15.67%

UBS downgraded NuScale from Neutral to Sell and cut its price target from $10 to $6, citing a five-plus-year construction timeline, a lack of firm customer commitments and an estimated $700 million of cumulative cash burn through 2028. The session's most consequential eligible decline, with almost $800 million in turnover and read-through pressure across advanced-nuclear equities.

Hewlett Packard Enterprise Company (HPE) +12.44%

Enterprise-infrastructure shares rallied after Oracle reported 121% cloud-infrastructure revenue growth, reinforcing demand expectations for AI servers and networking; HPE had also recently highlighted strong AI demand and an expanded Oracle networking relationship. One of the strongest large-cap moves, extending a volatile post-earnings sequence and highlighting aggressive rotation into AI infrastructure suppliers.

Dell Technologies Inc. (DELL) +11.98%

RBC Capital Markets initiated coverage with an Outperform rating and a $640 price target, citing Dell's position in the multiyear AI-infrastructure spending cycle. The nearly 12% jump added tens of billions of dollars in market value and carried Dell to a record closing level.

Super Micro Computer, Inc. (SMCI) +7.28%

AI-server suppliers rallied after Oracle reported 121% cloud-infrastructure growth, more than $30 billion of new AI-cloud contracts and delivery of over 300,000 GPUs since the prior quarter. A high-volume rebound in a heavily traded AI-server name, directly expressing the market's read-through from hyperscaler infrastructure spending.

Arista Networks, Inc. (ANET) +5.61%

Networking shares benefited from Oracle's accelerating AI-cloud buildout and the resulting read-through for high-speed data-center switching demand. A multibillion-dollar market-value gain in a major AI-networking supplier, broadening the hardware rally beyond server manufacturers.

Copart, Inc. (CPRT) -2.60%

Copart announced fiscal fourth-quarter results and its agreement to acquire ACV for approximately $1.9 billion in cash. The buyer's shares declined as investors assessed the purchase price, integration and execution risk. The negative buyer reaction contrasted sharply with ACV's 44% gain, creating a clear paired M&A trade with substantial combined turnover.
