Palantir cofounder Cohen sells over 20% of his stake in planned sale

Palantir cofounder and director Stephen Cohen sold shares worth more than $310 million over three days last week, as part of a trading plan adopted in December.

After a couple days of solid gains, Palantir is once again among the large-cap laggards putting downward pressure on the blue-chip S&P 500 index Tuesday.

There’s little fundamental news on the stock, though eagle-eyed equity analyst Brent Thill over at Jefferies spotlights more selling of the stock by company insiders. (Thill was one of the first to take note of a surge of selling by cofounder and CEO Alex Karp over the past year that reduced his holdings in the data analytics software company by 20%.)

Not to be outdone, Stephen Cohen, Palantir cofounder as well as president, secretary, and board member, sold more than 20% of his stake in the company over three days last week, according to Thill:

“We highlight a resumption of PLTR’s insider selling via Rule 10b5-1 trading plans in 2025, with co-founder and President Stephen Cohen selling $310M worth of shares over the last few days (~23% of his overall stake in PLTR).”

To be sure, the company signaled that some selling could be coming, writing in its annual report that Cohen had established new trading plans that would allow him to sell more than 4 million shares through September, without running afoul of Rule 10b5-1, the SEC rule on insider trading. (Karp also disclosed new stock-selling plans.)

Cohen’s sales last week represented the exercise of options for 3.75 million shares, which he immediately sold.

What’s to be made of all this selling? As we’ve said before, there are all sorts of reasons why insiders sell. So it’s a bit of a stretch to make these sales out to be a sign of things to come for Palantir shares.

After all, Cohen also dumped nearly 4 million shares in conjunction with the company’s IPO on September 30, 2020, generating proceeds of about $38 million.

That’s not a bad day’s work. But if he’d held onto that pile of stock, it would be worth more than $330 million now. According to FactSet data, Cohen has sold stock worth more than $750 million since the company went public. Karp has sold more than $3 billion worth.

US job growth crushes estimates in March, with the unemployment rate unexpectedly dipping to 4.3%

US hiring surged in March, with job growth of 178,000 well ahead of estimates while the unemployment rate unexpectedly edged down to 4.3%.

Economists had anticipated non-farm payrolls growth of 65,000 for the month with the unemployment rate holding steady at 4.4%

Event contracts had presumed that job growth would come in between 70,000 and 80,000, a sunnier view than Wall Street.

Prediction markets had anticipated roughly 70% odds that the unemployment rate would hold steady at 4.4%, with a much higher implied likelihood of an increase versus a decrease.

S&P 500 equity futures, which were modestly negative ahead of the report in thin holiday trading, were little changed in the immediate aftermath of this release. Treasury yields jumped, with the 10-year yield rising to 4.35% from 4.31%.

The inflationary impact of the higher crude prices in the wake of US-Israeli attacks on Iran and the subsequent challenges shipping oil through the Strait of Hormuz has been the dominant macroeconomic development of the past month, rather than US labor market data.

Before the conflict began, roughly 60 basis points of easing by the Federal Reserve was priced in for 2026. Heading into this release, that’s slimmed to just 5 basis points as US gas prices jumped above $4 per gallon.

The Federal Reserve’s “dot plot” from the March meeting still suggests that officials think it will be appropriate to lower the policy rate this year if the economy unfolds in line with their expectations.

The February jobs report had been a big disappointment, with jobs unexpectedly contracting and the unemployment rate edging higher. With this release, the February figures were revised to show an even larger decline of 133,000.

Strikes which had weighed on employment in health care during February, a critical source of US employment growth in recent years, seemingly reversed. The industry accounted for more than half of net job growth for March.

AI server cluster maker Penguin Solutions takes flight

Small-cap AI server cluster maker Penguin Solutions surged Thursday after posting better-than-expected Q2 revenue and profit numbers Wednesday after the close, along with an increase in full-year sales and profit guidance.

The company, which was known as Smart Global Holdings until July 2024, has positioned itself as a provider of “end-to-end AI infrastructure solutions.”

Its Advanced Computing division designs and sells computers, cabling, and cooling systems, the server racks and clusters of racks AI data centers need. Its other main division sells flash and DRAM memory products.

It’s a pretty small company, with a fully diluted market cap of just over $1 billion and roughly 2,900 employees, according to FactSet.

The stock is volatile. Penguin dove during last year’s tariff tantrum that followed “Liberation Day” in April. Then it turned tail and doubled through early October amid a surge of call options activity, which tends to reflect retail interest. From the October peak, it then plunged by about 50%, before Thursday’s renaissance.

For what it’s worth, call options activity in Penguin is pretty busy today, too — relatively speaking — with roughly 2,625 traded as of 1:15 p.m. ET. That’s the most since early January, when the company last reported quarterly numbers. The average volume over the previous 25 trading sessions is about 325 calls a day, FactSet data shows.

Momentum returns to optics stocks as the release valve for AI optimism

Potentially imminent end to the war? Buy optics stocks.

Maybe not? Buy optics stocks anyway.

Effectively all the juice left in the AI trade is coming from optics (and memory) stocks. And the latter group is taking a bit of a breather today while the former continues to surge.

Shares of Ciena Corp., Lumentum, and Coherent are building on recent big gains and among the biggest gainers in the S&P 500 near midday, while Applied Optoelectronics is also surging on Thursday.

These companies all provide solutions that help information move around in data centers, and thus are key beneficiaries of the aggressive capex plans of hyperscalers. Nvidia has invested $2 billion apiece in Coherent and Lumentum in deals that also include purchase commitments.

Space stocks rip during a topsy-turvy day for the equity market

Satellite-services-from-space stocks surged Thursday after reports that Amazon is in talks to buy Globalstar, which provides voice and connectivity services from its satellite network. It also can’t hurt that the general mood around space is ebullient, following the successful launch of Artemis II on Thursday.

Planet Labs and ViaSat also soared on the news.

The gains for EchoStar — seen as a backdoor play at pre-IPO SpaceX exposure — and Rocket Lab were more muted, perhaps because a deep-pocketed competitor like Jeff Bezos getting serious about space services could complicate the plans of the two largest commercial space launch companies.

Rocket Lab and SpaceX see launch services as key to their aspirations of being major providers of voice and data services from low-Earth orbit satellites.

Tesla CEO Elon Musk’s SpaceX is the dominant provider of such services, and the early rumors on the company’s planned IPO — expected to be the largest ever — suggest the market is very excited about the prospects for the industry.

Elsewhere in the space stock world, Intuitive Machines — a maker of space infrastructure that provides services to NASA for lunar missions — also rose.
