The investment community eagerly awaits a particular filing every quarter -- and it's one that offers us a view into the latest moves of the world's top investors. This particular moment happened a few weeks ago when institutional investors managing at least $100 million filed their 13F forms with the Securities and Exchange Commission (SEC). These forms show the latest buys and sells of these expert investors along with information on their current holdings.

Why are the rest of us so eager to see the latest 13F filings? They may offer us inspiration for our own portfolios as we search for investing ideas. Of course, these billionaires, like the rest of us, don't score a win with every stock pick. But they do have significant track records of success, so it's worth studying their moves -- and in some cases following them.

In the most recent quarter, billionaire Ole Andreas Halvorsen took a big step in the hot area of artificial intelligence (AI), selling all of his Broadcom (NASDAQ: AVGO) shares and piling into this year's top Dow Jones Industrial average performer. Let's dive in and consider if it could be the right move for you.

From Tiger Cub to Viking

First, a quick look at this top investor. At the helm of Viking Global Investors, Halvorsen helps manage more than $27 billion in securities falling under 13F reporting requirements. He is known as a "tiger cub," having spent the earlier days of his career working at Julian Robertson's Tiger Management, one of the first hedge funds, before launching Viking back in 1999.

In the third quarter, Halvorsen and his team made 23 new purchases and added to 21 current positions, but they also sold out of 22 stocks and reduced holdings of 26. So, they favored selling, but not by a huge degree. It's important to keep in mind that in some cases selling is done to lock in profits and isn't necessarily linked to a loss of faith in a particular company or the market in general.

Now, let's consider Halvorsen's big AI move in the third quarter. The billionaire sold his entire position in Broadcom, a company that's seen its shares advance in recent years thanks to its key role in networking. About 99% of today's Internet traffic passes through some sort of Broadcom technology. Halvorsen originally bought the shares in the second quarter of this year, so this wasn't a long-term holding. Broadcom shares may have been a winning investment, though, as they rose 30% from the start of the second quarter through the end of the third quarter.
