Market Movements: Key Companies Making Waves

Here’s a rundown of some major moves happening in the market:

Super Microcomputer — The company’s shares jumped about 17% following the preliminary results for the fourth quarter, which revealed stronger-than-expected profitability. This somewhat made up for revenues that landed near the lower end of the guidance.

Dell Technologies and Hewlett Packard Enterprise — Buoyed by Super Microcomputer’s growth, these companies also saw gains, with both up more than 4% in pre-market trading due to better-than-expected preliminary results.

Pegasystems — Unfortunately, shares plummeted over 14% as the software firm reported second-quarter results that didn’t quite meet Wall Street’s expectations. Adjusted earnings came in at 35 cents per share, falling short of the 43 cents predicted by analysts.

Oklo and X-Energy — Shares of these nuclear reactor suppliers rose in pre-market trading. A report indicated that they are collaborating with the Trump administration to speed up the development of nuclear power plants aimed at serving AI data centers. X Energy rose by 4%, while Oklo increased by more than 3.5%.

Rocket Lab — The company’s shares climbed 4% after landing a $266 million contract with the U.S. Air Force. This deal entails launching 12 suborbital vehicles, with completion expected by the end of 2028.

Calmaine Foods — Shares fell more than 4.5% after reporting a surprising loss of 76 cents per share in its fiscal fourth-quarter report. Analysts had anticipated earnings of 8 cents per share. The losses were attributed to historically low inflation-adjusted egg prices during that period.

GE Vernova — Despite reporting strong sales growth in the second quarter and raising its full-year outlook, GE Vernova saw its shares drop over 7%. CEO Scott Strzyk remarked that the company’s $176 billion backlog should support ongoing revenue growth and margin expansion.

AT&T — The telecommunications giant’s shares increased by 3%, even amidst a mixed second-quarter earnings report. AT&T’s adjusted earnings were 65 cents a share, beating the FactSet consensus of 59 cents.

Philip Morris International — Shares dipped by 0.5% following a weaker-than-expected outlook for the upcoming third quarter. The company projected earnings per share between $2.20 and $2.25, which falls short of the $2.42 expected by analysts. Still, their second-quarter results surpassed expectations in both profit and sales.

CME Group — Shares rose 1% after the exchange reported better-than-anticipated profits and sales for the second quarter. They noted that the first half of 2026 marks their best six months on record.
