Want to trade alongside Wall Street’s biggest players?

Thanks to Form 13F filings, you can.

Here’s the deal: any hedge fund or investment manager with more than $100 million under management is required by the SEC to file a “13F” once a quarter.

These filings reveal their stock holdings – essentially giving you a peek into the portfolios of the world’s best investors.

James Altucher once called 13Fs a “cheat code” for individual investors because they let you see exactly what the billionaires on Wall Street are buying and selling.

Now, it’s not exactly a crystal ball. There’s a 45-day delay so you’re still looking slightly in the rearview mirror.

But the insights are still incredibly valuable.

The latest round of 13Fs hit just a few days ago.

Translation: we now know what the smart money was buying last quarter.

Let’s dive into the latest filings and see where the smartest money on Wall Street is placing its bets.

Greg Abel’s Berkshire Hathaway

It feels strange typing “Greg Abel’s Berkshire Hathaway” instead of “Warren Buffett’s.”

But the torch has been passed.

This was Greg Abel’s first quarter at the helm and he made plenty of big moves.

• Buys: Alphabet (GOOG/GOOGL), Delta Airlines (DAL), Macy’s (M)

• Sells: Amazon (AMZN), Visa (V), Mastercard (MA), UnitedHealth (UNH), Dominos Pizza (DPZ)

All of the sales listed were complete exits.

Overall, Abel reduced the company’s stock portfolio from 42 positions down to 29 during the quarter.

Bill Ackman’s Pershing Square

Ackman’s hedge fund Pershing Square made some interesting adjustments in Q1:

• Buys: Microsoft (MSFT), Amazon (AMZN)

• Sells: Alphabet (GOOG/GOOGL), Meta Platforms (META), Hilton (HLT)

I pay close attention to Ackman’s moves because he runs a concentrated portfolio – usually around 10-12 names.

Ackman revealed on X that he began accumulating shares of Microsoft in February after the stock declined post earnings.

The hedge fund manager said investors have become overly concerned about Microsoft’s competitive positioning in AI and the long-term growth outlook for its Azure cloud business.

To fund the new position, Ackman trimmed shares of Alphabet.

That doesn’t mean he suddenly dislikes Alphabet. Rather, in a portfolio with finite capital, Ackman currently prefers Microsoft.

Brad Gerstner’s Altimeter Capital

Gerstner also runs a concentrated portfolio focusing on technology stocks.

Here are his latest moves:

• Buys: Nvidia (NVDA), Arm Holdings (ARM), Uber Technologies (UBER), CoreWeave (CRWV), Taiwan Semiconductor (TSM)

• Sells: Alphabet (GOOGL), Coupang (CPNG), Confluent (CFLT), Zillow (Z)

At a time when the financial media is screaming “BUBBLE!” at the AI trade, Gerstner is loading up on the biggest players.

I agree with Gerstner that these names are worth picking up on selloffs.

Leopold Aschenbrenner’s Situational Awareness

This is a name you’ll likely start hearing more.

Leopold Aschenbrenner is a 23-year-old former OpenAI researcher who launched Situational Awareness, a hedge fund built around the belief that artificial general intelligence is arriving far sooner than most investors expect.

In just about a year, the fund reportedly grew from roughly $225 million in seed capital to around $5.5 billion.

Here are his latest moves:

• Buys: VanEck Semiconductor PUTS (SMH), Nvidia PUTS (NVDA), Broadcom PUTS (AVGO), AMD PUTS (AMD)

• Sells: Intel CALL (INTC), CoreWeave CALL (CRWV), Bloom Energy (BE), Lumentum (LITE)

Aschenbrenner made some bearish bets in Q1 – buying puts on the semiconductor companies.

It’s important to note, however, that there’s a 45-day delay between when the quarter ended and when Aschenbrenner’s 13F went public.

So there’s a chance he’s since sold these bearish bets.

Investors like Abel, Ackman, and Gerstner are more long-term oriented investors, so their 13Fs are more reliable as investment signals for retail investors.

Why This Information Matters

1. Spot Trends Before the Market Moves – Seeing multiple fund managers piling into similar stocks can indicate emerging trends.

2. Follow the Smart Money – If Ackman is buying a stock that’s currently under the radar, it might be worth investigating.

3. Avoid Potential Pitfalls – If hedge funds are dumping a stock you own, it could signal risks that aren’t yet fully priced in.

While 13F filings shouldn’t be followed blindly, they are a powerful tool for identifying high-conviction trades from the world’s top investors.

By keeping an eye on these reports, you can make more informed investment decisions and stay ahead of the market.
