UnitedHealth Group jumps after Berkshire Hathaway discloses stake

UnitedHealth Group soared in after-hours trading after Warren Buffett’s Berkshire Hathaway revealed that it purchased and held 5 million shares of the embattled healthcare giant as of the end of the second quarter, a new position for the conglomerate.

That was a roughly $1.6 billion position as of June 30 — but less now, even after the stock popped nearly 8% higher on this announcement.

It’s been a rough year for health insurers in general, but especially for UnitedHealth. This is a rare highlight during a year to forget. The company cratered after reporting Q1 earnings, saw its CEO leave and pulled guidance shortly thereafter, then fell out of bed again after posting disappointing second-quarter results at the end of July. Oh, and it’s also facing a probe from the Department of Justice into its Medicare Advantage practices.

All this bad news has pushed the company’s stock price down 46% year to date as of Thursday’s close, but that also may have been what made it attractive to a value-oriented shop like Berkshire.

At the end of the second quarter, UNH’s forward price-to-earnings multiple was about 13.1x, versus a trailing five-year average of 19.2x.

Since the end of Q2, its valuation has risen, but for a bad reason: its earnings estimates keep getting chopped.

Samsung’s massive Q1 fails to lift Sandisk, other data center plays

Almost all memory stocks slipped Tuesday, despite getting a positive update on the massive flood of money pouring into the sector from the AI build-out, as the potential escalation of the US war with Iran Tuesday evening overshadowed Samsung’s blowout numbers.

Korean chip giant Samsung Electronics reported preliminary Q1 results showing operating profit up by 755% compared to Q1 2025, trouncing pretty elevated expectations for a gain of about 550%.

Samsung is the world’s largest producer of NAND and DRAM chips. Once considered low-value commodity inputs to tech products, NAND and DRAM prices have exploded over the last six months amid a hyperscaler scramble to secure chips that can manage the surfeit of data produced by AI.

The same dynamics have made memory plays like Sandisk, Western Digital, and Micron some of the best-performing stocks in the S&P 500 over the last 12 months.

But other than Seagate Technology Holdings, those stocks were down Tuesday as of 11:15 a.m. ET, as the surge in oil prices and ongoing war with Iran muted much of the AI data center trade excitement. Bellwethers like Nvidia and hyperscalers like Oracle and Meta were struggling early, as were data center input makers like Corning and Coherent, AI power plays like GE Vernova, Vertiv Holdings, and even hard-hat builders of the shells that house all those AI servers.

On the other hand, some so-called optical stocks — makers of fiber-optic connections that quickly shift data between users, hyperscalers, and all around data centers themselves — were up. Lumentum and Arista Networks, two popular optical stocks, were showing resilience.

Paramount surges on bullish options activity, 1 day after $24 billion Gulf backing report

Paramount Skydance shares surged more than 9% shortly after markets opened on Tuesday, on pace for their best day since news that the company had emerged victorious in the Warner Bros. bidding war broke in late February.

The entertainment giant is being propelled by bullish options activity, with about 17,000 call options having changed hands as of 10:03 a.m. ET, already ahead of the 20-day average for a full session.

The market move comes a day after reports that three Gulf sovereign wealth funds would back Paramount’s offer for WBD to the tune of $24 billion. Those working on the deal don’t expect the Gulf funds’ involvement to spark any additional regulatory reviews.
