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 13F’s a “cheat” code for individual investors because they let you see exactly what billionaires like Warren Buffett and Bill Ackman 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.

And as of just a few days ago, we’ve officially hit that 45-day mark since Q2 ended.

Translation: Fresh 13Fs just dropped.

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

Bill Ackman’s Pershing Square

Ackman’s hedge fund Pershing Square made some interesting adjustments in Q2:

• Buys: Amazon (AMZN), Alphabet (GOOG), Brookfield Corporation (BN), and Hertz Global (HTZ), Hilton (HLT).

• Sells: Reduced stake in Canadian Pacific Kansas City Limited (CP).

Interesting to note: Ackman added to Brookfield Corporation and Hertz Global for the second consecutive quarter.

And in a shift from the prior quarter, he moved from selling Alphabet and Hilton in Q1 to buying both in Q2.

I pay close attention to his moves because he runs a concentrated portfolio – usually around 12 names.

That’s a strategy I relate to at The Million Mission, where I focus on a few high-conviction ideas rather than the sprawling, ultra-diversified approach used by most large money managers.

Warren Buffett’s Berkshire Hathaway

Buffett’s Q2 moves made waves:

• Buys: UnitedHealth (UNH), Nucor (NUE), Lennar (LEN), D.R. Horton (DHI).

• Sells: Apple (AAPL), T-Mobile (TMUS), Davita (DVA), Charter Com. (CHTR).

UnitedHealth was the big surprise from Buffett. The stock spiked on the news of Berkshire’s new stake.

Berkshire also continued to sell down its Apple stake.

However, it’s still Berkshire’s largest position at 22% of the portfolio.

American Express (AXP) and Bank of America (BAC) are Berkshire’s next largest positions at 19% and 11%, respectively.

David Tepper’s Appaloosa Management

Last week, David Tepper, who oversees over $8 billion in AUM at Appaloosa, filed his fund's 13F.

Tepper’s aggressive style was evident in his Q2 filings:

• Buys: UnitedHealth (UNH), Nvidia (NVDA), Amazon (AMZN), Taiwan Semi (TSM), Intel (INTC).

• Sells: S&P 500 puts, Apple puts (AAPL), PDD Holdings (PDD), Alibaba (BABA).

Like Buffett, Tepper loaded up on UnitedHealth.

He also went heavy into big-cap tech while cutting back on bearish bets and Chinese exposure.

That’s a major shift toward risk-on and a complete 180 from Tepper’s previous stance of “buying any Chinese stocks he could get his hands on.”

Michael Burry’s Scion Asset Management

Michael Burry rose to fame for his 2007 bet against the housing market – a move famously portrayed in The Big Short.

Here are his recent portfolio moves:

• Buys: UnitedHealth calls (UNH), Regeneron calls (REGN), Lululemon calls (LULU), Meta calls (META).

• Sells: Nvidia puts (NVDA), Alibaba puts (BABA), PDD Holdings puts (PDD), JD.com puts (JD).

Burry’s gone from doomsayer in Q1 to full-blown bull in Q2.

Now, remember there’s a 45 day delay on these 13F filings.

Depending on when Burry closed his positions, he could’ve made an absolute killing on his put positions on NVDA, BABA, PDD, and JD in Q2 (If he sold early in April when the market was selling off during Trump’s tariff scare).

Or he could’ve lost his shirt (If he held through the tariff scare when the market subsequently rallied sharply).

Important to note, however: Burry’s most recent positioning is extremely bullish.

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.
