Cathie Wood's Ark Invest made some eyebrow-raising moves on Thursday, dumping over $10 million in Palantir Technologies Inc. (PLTR) while simultaneously loading up on Broadcom Inc. (AVGO). The timing? Let's just say it got interesting when CNBC's Jim Cramer decided to weigh in.

Out with Palantir

Ark sold 58,741 shares of Palantir through its ARK Next Generation Internet ETF (ARKW), a transaction worth approximately $10.4 million. The stock closed at $176.86, down 2.65% on the day, which probably didn't help anyone's mood.

Here's where it gets fun. The sale happened right around the time Cramer tweeted, "Look out Palantir shorts, here we go again!" If you're familiar with Wall Street superstitions, you know about the so-called "Cramer Curse"—the idea that stocks tend to stumble after Cramer gives them a public pat on the back. Whether you believe in curses or coincidences, the timing was certainly noteworthy.

The broader context matters too. Palantir, co-founded by Peter Thiel, has been riding the wave of defense sector momentum. President Donald Trump recently floated a $1.5 trillion U.S. defense budget proposal for 2027, a significant jump from current spending levels. That should theoretically be good news for a company deeply embedded in defense and intelligence work, but markets are fickle creatures.

In with Broadcom

So what did Ark do with that $10.4 million? Turned right around and bought 31,573 shares of Broadcom (AVGO) through the same ARKW fund. Broadcom's stock closed at $332.48, down 3.21%, so it wasn't exactly a banner day for tech stocks across the board.

The investment comes on the heels of Broadcom's fourth-quarter earnings report, which showed solid performance in a challenging environment. Analysts have been recalibrating their price targets, weighing the company's strong fundamentals against questions about its AI backlog and future demand. Ark's bet signals confidence that Broadcom's position in AI infrastructure and semiconductors will pay off over the long haul, even if the stock took a breather on Thursday.

Flying Taxis Join the Portfolio

In a separate transaction, Ark's ARK Space & Defense Innovation ETF (ARKX) picked up 162,270 shares of Joby Aviation Inc. (JOBY), worth about $2.5 million. Joby's stock ended the day at $15.25, down 1.93%.

The timing aligns nicely with Joby's announcement of a $61.5 million investment to expand its Ohio manufacturing facility. The company is aiming to produce four aircraft per month by 2027, which is ambitious for a sector that's still figuring out regulatory hurdles and consumer acceptance. But if anyone's going to bet on electric air taxis becoming a thing, it's Cathie Wood.

The Rest of the Day's Moves

Ark didn't stop there. The firm also made several other trades through its space and defense ETF:

• Sold 20,105 shares of Kratos Defense and Security Solutions Inc. (KTOS)
• Sold 24,865 shares of Rocket Lab Corp. (RKLB)
• Bought 73,097 shares of Archer Aviation Inc. (ACHR)

The pattern here? Ark seems to be rotating within the defense and urban air mobility spaces, trimming some positions while doubling down on others. It's the kind of active management that keeps things interesting, even if every call doesn't pan out.

What Does It All Mean?

Ark's trading activity reflects a broader strategic repositioning as geopolitical tensions heat up and the AI boom continues to reshape tech investing. Selling Palantir doesn't necessarily mean Wood has lost faith in the company—it could simply be profit-taking or portfolio rebalancing. The equal-sized Broadcom purchase suggests she's still bullish on tech, just picking different horses.

As for the Cramer Curse? Well, superstitions persist because they're occasionally right. But serious investors probably shouldn't base their strategies on Twitter timing, even when the coincidences are entertaining. What matters more is how these companies perform over the coming quarters as defense budgets expand, AI infrastructure buildout continues, and the urban air mobility market inches closer to reality.

For now, Ark is making big bets on where the future is headed. Whether those bets pay off is the billion-dollar question that keeps everyone watching.
