Cathie Wood’s investment strategy is simple: ARK ETFs typically buy shares in emerging, high-tech companies across fields like artificial intelligence, blockchain, DNA sequencing, energy storage, and robotics.

During the last week of October, Wood added roughly 2.5 million shares of Archer stock to the Ark funds. Considering shares of Archer are trading for less than $5 and Tesla's recent valuation expansion has made the stock a bit pricey, did Wood just make the trade of a lifetime?

Cathie Wood had yet another helping to some of her favorite large-cap AI stocks over the past month. Indeed, as interest rates fall and Donald Trump makes his return to the White House, I see Cathie Wood and her line of Ark Invest funds standing out as major winners.

Between Oct. 28 and Oct. 30, Ark scooped up 2.5 million shares of Archer, spread across three separate purchases. Given Archer's seemingly low stock price, it may look like Wood is buying the dip on a potentially lucrative opportunity set to disrupt the EV market.
