Every few months, we take a look at what top investors — known in market-speak as “whales” — are placing big bets on. Specifically, which stocks they have at least 20% of their portfolios in.

High concentration in just one or a few companies is what drives many top investors’ outperformance, so having a gander at their top positions can be an insightful exercise. But the strategy can also be risky in the sense that much of a portfolio’s performance depends on a small number of holdings.

Many of the bets are the same as in September 2024, the last time we checked in. Portfolio weightings change, however, either as particular stocks see outsize gains or losses or as fund managers add to or reduce their positions.

One notable update is that Warren Buffett has continued to reduce his position in Apple, a move that some view as a protective measure amid an expensive market. Another is that David Einhorn has upped his position in his own homebuilding firm, Green Brick Partners, as the stock has fallen 29% since September.

Using data from GuruFocus.com‘s list of 145 top investors and funds, we’ve compiled below the stocks that make up at least one-fifth of their respective funds. The stocks’ weightings in September 2024 are also included.

The stocks are listed in ascending order of their weightings in their respective portfolios.
