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.

Roblox jumps after announcing $3 billion share buyback plan

Roblox rallied in postmarket trading on Tuesday after unveiling its first-ever share repurchase program.

The somewhat controversial, but certainly popular, gaming company has put forth a plan for $3 billion in future stock buybacks, with the intention to back up to $1 billion over the next twelve months. The stock subsequently jumped 4% after-hours.

On Tuesday, Naveen Chopra, Chief Financial Officer of Roblox said:

“Investing in continued growth will always be our highest priority, but the strength of our balance sheet and free cash flow generation allows us to support industry leading innovation while simultaneously reducing dilution.”

As of Q1 2026, Roblox had $6.2 billion in total cash, cash equivalents, and investments (for a net $5.2 billion after subtracting their $1.0 billion dollars in debt). The company posted a consolidated net loss of $248 million in Q1.

While management has the cash on hand for a $3 billion buyback, their stock been taking hits recently — falling 28% over the past month (and 45% since the beginning of the year) as the company adjusts its safety standards. In April, the video game company slashed its full year guidance due to age-verification hurdles which have slowed growth.

Cava rallies after Q1 results impress and management hikes full-year guidance

Cava jumped 8% after the bell on Tuesday after the fast-casual Mediterranean restaurant chain was able to bring in more customers and drive up more revenue than expected in the first quarter, with management signaling that this momentum is poised to continue.

Here are the numbers:

  • Q1 revenue of $434.4 million (compared to analyst estimates of $418.2 million).

  • Q1 adjusted EBITDA of $61.7 million (estimate: $57.3 million).

  • Full-year guidance for same-restaurant sales growth of 4.5% to 6.5%, up from its prior guidance of 3% to 5% and above estimates for 4.95%.

The company also posted traffic growth of 6.8% — blowing away salad competitor Sweetgreen’s traffic decrease of 11.2% in the first quarter.

“We’re creating a bit of a bridge in a K-shaped economy and becoming very accessible for the low-income cohorts,” CFO Tricia Tolivar told Restaurant Dive. “When we look at our restaurant stratified based on median household income, we’re seeing tremendous strength in the lower-income cohorts.”

The performance of these fast-casual establishments (or slop bowl chains) has been a way to keep an eye on our increasingly unequal economy. Interestingly, as especially younger consumers seem to be pulling back, at some of these restaurants, Cava continues to perform well.

Nintendo climbs for third day as China ramps up its memory production

Nintendo shares are climbing on Tuesday, marking the company’s third straight session of gains — something it hasn’t done since early March. The Mario maker’s US-listed ADRs were up about 4% in Tuesday morning trading.

The return of the Switch 2 game bundle appears to have stoked investor optimism in the company’s console sales, while China’s accelerating memory production plans could alleviate some of Nintendo’s pain from the “RAMpocalypse.” For the better part of a year, memory prices have surged as AI demand hoovers up compute power. That’s squeezed video game console makers — and the broader consumer electronics industry.

Tracking the performance of Nintendo ADRs against memory giant Micron helps put this move in perspective. Nintendo is a big memory consumer, and not in the front of the line in terms of securing supply. Micron, obviously, benefits from its offerings being in high demand.

Tuesday’s price action is just a drop in the bucket, and comes as part of a recent stretch where the stock market’s high-flyers are having their wings clipped while beaten-up laggards rally.

In its first-quarter results on Monday, Chinese DRAM producer CXMT said it’s ramping up production and issued bullish guidance. The company is planning an IPO later this year, and it could be China’s biggest of the year.

For Nintendo, more global memory production could see rising costs start to deflate, improving margins in a vital year for its new console.
