You can't get rich simply by copying billionaires' moves, but there's still something irresistible about following their top stock picks.
The billionaires we're about to talk about have larger-than-life reputations when it comes to investing other rich people's money. Meanwhile, their resources for research, as well as their intimate connections to insiders and others, can give them unique insight into their stock picks.
Studying which stocks they're chasing with their capital can be an edifying exercise for retail investors. There's a reason the rich get richer, for one thing. But it's also helpful to see where billionaires sometimes make mistakes — at least in the short term.
No matter how successful they've been in the past, all investors are fallible. Those who've amassed multibillion-dollar personal fortunes have merely made more money being right than they've lost when getting it wrong.
Need proof? As Chairman and CEO Warren Buffett wrote in Berkshire Hathaway's 2022 annual report (PDF): "In 58 years of Berkshire management, most of my capital-allocation decisions have been no better than so-so. Our satisfactory results have been the product of about a dozen truly good decisions."
Berkshire's "satisfactory results" happen to be a stock that has generated compound annual growth of almost 20% since 1965. The S&P 500 delivered compound annual growth of not quite 10% over the same span.
Without further ado, here are five notable top stock picks from the billionaire class.
In each case, the billionaire below initiated a substantial position or added to an existing one in the fourth quarter of 2025.
Stake values and portfolio weights are as of December 31, 2025. Data courtesy of S&P Global Market Intelligence, YCharts, WhaleWisdom, Forbes and regulatory filings made with the Securities and Exchange Commission, unless otherwise noted.
- Billionaire investor: Steve Cohen (Point72)
- Stake value: $1.9 billion
- Percent of portfolio: 2.1%
Steve Cohen is probably best known for using his estimated net worth of $23 billion to buy the New York Mets. But he's also known for adding to positions when stocks he already likes a lot are on sale.
Perhaps that's why his family office — Point72 Asset Management based in Stamford, Connecticut — massively upped its stake in Nvidia (NVDA) when shares trailed the broader market in Q4.
Point72, with $221 billion in assets under management (AUM), bought another 2.7 million shares in NVDA – a 38% increase – over the course of the fourth quarter, adding to a position the firm initiated in 2023. With nearly 10 million shares worth $1.9 billion as of the end of Q4, the stock rose to become the fund's single largest position. Previously, it was the fund's third-largest holding.
Point72 also increased its stakes in Amazon.com (AMZN) and Taiwan Semiconductor Manufacturing (TSM), among other AI plays.
- Billionaire investor: Daniel Sundheim (D1 Capital Partners)
- Stake value: $444.6 million
- Percent of portfolio: 4.2%
Daniel Sundheim's D1 Capital Partners made a name for itself during its seven years of existence. The New York hedge fund began trading with "only" $5 billion in capital. Today, D1 boasts nearly $28 billion in AUM.
Along the way, Sundheim built an estimated net worth of $2.6 billion, according to Forbes. In a nod to his precocious success, some wags called Sundheim the LeBron James of investing.
Sundheim clients certainly hope he brings his scoring touch to D1's position in Sea Limited (SE). The hedge fund more than doubled its stake in the Singapore-based online gaming, shopping and financial services company in Q4 – a position it initiated only a quarter earlier.
With 3.5 million shares worth $444.6 million as of December 31, SE leapfrogged to become the fund's eighth-largest holding from 16th place at the end of Q3. SE lost about a quarter of its value during the fourth quarter, suggesting Sundheim spied a bargain.
- Billionaire investor: Stephen Mandel (Lone Pine Capital)
- Stake value: $598.8 million
- Percent of portfolio: 4.4%
It should come as no surprise that yet another billionaire investor added to yet another big bet on a mega-cap tech stock in Q4. After recovering sharply from the market's April bottom, shares in Broadcom (AVGO) traded essentially sideways in Q4.
Stephen Mandel picked up another 180,000 shares in the chipmaker in the final quarter of the year – a position he initiated in the third quarter. Mandel amassed an estimated net worth of $2.5 billion by knowing how to spot momentum, so count this as encouraging news for AVGO bulls.
Mandel's Lone Pine Capital hedge fund ($13.6 billion AUM) now owns a stake in AVGO worth nearly $600 million as of December 31. At 4.4% of the portfolio, Broadcom is the fund's eighth-largest holding, up from 13th place at the end of Q3.
In an ongoing theme, the hedge fund also added to its stake in Microsoft (MSFT) in Q4.
- Billionaire investor: David Tepper (Appaloosa)
- Stake value: $396 million
- Percent of portfolio: 5.7%
Meta Platforms (META) swooned by nearly 20 percentage points a little over halfway through the fourth quarter and David Tepper was there for it.
The owner of the NFL's Carolina Panthers accumulated an estimated net worth of $23.7 billion in part by knowing how to spot a bargain. His Appaloosa hedge fund (AUM $6.9 billion) boosted its stake in the Facebook, Instagram and WhatsApp parent in Q4 by more than 60%, or 230,000 shares.
Appaloosa, which has owned Meta since early 2016, now holds 600,000 shares worth nearly $400 million as of the end of the fourth quarter. With a weight of 5.7%, META is Tepper's fifth-largest holding, up from No. 9 in the previous quarter.
The hedge fund also added to positions in Micron Technologies (MU) and Microsoft.
- Billionaire investor: Philippe Laffont (Coatue Management)
- Stake value: $2.5 billion
- Percent of portfolio: 6.3%
Philippe Laffont built an estimated net worth of $7.9 billion partly by knowing how to stick with winners. Such skills were on display when Laffont's Coatue Management hedge fund (AUM $69.5 billion) increased its stake in Microsoft by more than 11% during the final quarter of 2025.
Coatue, which has owned MSFT since the third quarter of 2021, bought another 528,926 shares in the tech giant. The fund now holds 5.1 million shares worth $2.5 billion as of December 31, according to regulatory filings. With a portfolio weight of 6.3%, MSFT is the New York hedge fund's second-largest position.
If nothing else, Laffont finds himself in good company. Not only is Microsoft one of the most popular blue chip stocks among hedge funds, but it also gets the highest consensus recommendation of all 30 Dow Jones stocks.
It also doesn't hurt that MSFT has done extraordinary things for truly long-term shareholders. Anyone who put $1,000 into MSFT stock a couple of decades ago has clobbered the S&P 500 by a wide margin.
