Cathie Wood’s Bold Moves: Loading Up on Klarna, Synopsys, and Rubrik While Trimming Shopify and Roblox

Cathie Wood just reshuffled her deck—and the market's watching every play.

ARK's flagship funds snapped up fresh positions in Klarna, Synopsys, and Rubrik, signaling strong conviction in fintech disruption, semiconductor design, and data security. Meanwhile, she trimmed exposure to Shopify and Roblox—two former darlings now facing tougher growth comparisons.

Wood’s never been one to follow the herd. While Wall Street frets over valuation ceilings, she’s betting big on the next wave of tech inflection points. Klarna’s buy-now-pay-later model? Synopsys’s AI-driven chip design tools? Rubrik’s ransomware protection? All classic Wood—high-conviction, long-term, and just contrarian enough to make traditional fund managers sweat.

But let’s be real—trimming Shopify and Roblox isn’t exactly a vote of no confidence. More like taking some chips off the table after a monster run. Because even innovation investors occasionally remember what a “profit” is.

One cynical take? Maybe she’s just making room for more crypto ETFs. Wouldn’t put it past her.
