Super Investors Are Buying AI Stocks

Joseph Carlson After Hours•May 18, 2026

Summary

In this video, Joseph analyzes the recent 13F filings of several 'super investors,' highlighting a significant divergence in strategy regarding big tech. The main thesis revolves around the 'moat' of companies like Microsoft and Google. While Chris Hohn of TCI has aggressively sold Microsoft due to fears that AI reduces software friction and threatens its enterprise dominance, Bill Ackman has done the exact opposite, dumping Google to build a massive position in Microsoft. Joseph notes that these investors prioritize moat stability over price, but have different tolerances for perceived risks.

Joseph also reviews the performance and trades of other notable managers. He discusses Dev Kantesaria's conviction in FICO despite market pressure and Berkshire Hathaway's recent portfolio cleaning under Greg Abel, which involved selling off positions managed by the departed Todd Combs while buying heavily into Google. Joseph concludes by warning that funds missing out on the current 'big tech' bull market, such as Terry Smith's Fundsmith or the newly managed Akre Capital, are struggling to compete with broader indexes like the S&P 500.

MSFT: Bill Ackman bought a 15% position while Chris Hohn sold 83% of his stake. Joseph sides with Ackman, believing the moat remains intact.

GOOGL: Heavily bought by Berkshire Hathaway and Li Lu (who has 50% of his portfolio in it), though sold by Altimeter and Bill Ackman.

AMZN: A cornerstone of Bill Ackman's portfolio; Joseph agrees with this bullish stance.

ASML: Added by Dev Kantesaria; Joseph considers it a top performer with an incredible technological lead.

V & MCO: Favored by investors like Chris Hohn and Li Lu for their credit rating and network moats.

UBER: A new addition for Pat Dorsey and Brad Gerstner, though Joseph notes it faces potential threats from autonomous vehicles.
