When you think about Warren Buffett's investment style and the stock trading activity of Rep. Marjorie Taylor Greene, you probably don't imagine much overlap. But it turns out the Georgia Congresswoman and the Oracle of Omaha have more in common than you'd think—at least when it comes to their stock portfolios.
Greene has quickly become one of the most closely watched members of Congress for stock trading activity, thanks to impressive returns and timing that has occasionally raised eyebrows. And when you look at her holdings alongside those of Berkshire Hathaway (BRK.B), nine stocks show up in both portfolios.
Here's what they're both betting on.
The Nine Stocks They Both Own
According to government disclosure data tracking Greene's trading activity, she and Buffett's Berkshire Hathaway share positions in some of the biggest names in the market. Let's break them down:
Alphabet (GOOGL): The search and advertising behemoth is a frequent purchase for Greene, who has bought shares seven times in 2025 alone, plus multiple purchases before that. For Buffett, Alphabet is a relatively new addition—he unveiled an initial stake in the third quarter that quickly became a top-ten holding worth over $4 billion.
Amazon.com Inc (AMZN): Another Magnificent Seven stock on both lists. Greene has been particularly active here, buying shares in 11 separate transactions in 2025 and several times previously. Berkshire owns more than $2 billion worth of Amazon stock, making it a top-20 holding in the portfolio.
Apple Inc (AAPL): The third Magnificent Seven stock they share, and this one's a big deal for Buffett. Apple is currently the largest investment holding in the Berkshire portfolio, with over 238 million shares representing nearly $64 billion—about 21% of the entire portfolio, according to CNBC. Greene has purchased Apple stock five times in 2025, with her most recent trade in May.
American Express (AXP): This financial services company is one of Buffett's longtime favorites and currently the second-largest holding in Berkshire's portfolio, representing around 17% of total investments. For Greene, it's a much smaller bet—just one purchase in May totaling between $1,000 and $15,000.
Chevron Corporation (CVX): The oil giant ranks as Berkshire's fifth-largest stock position, representing roughly 6% of the portfolio. Greene's purchases in Chevron stretch back years, with buys in 2021 and 2022, plus three more purchases in 2025.
Coca-Cola Inc (KO): The beverage company is one of Buffett's most famous long-term holdings and currently the fourth-largest position at 9.4% of Berkshire's investment portfolio. Greene purchased Coca-Cola stock back in 2021 but hasn't added to the position since.
Occidental Petroleum Corporation (OXY): This oil company is a top-10 holding for Berkshire, which also owns approximately 27% of the entire company. Greene has been actively buying, with four purchases in 2025 alone.
Visa Inc (V): The credit card and payment processing giant is a top-20 holding for Berkshire. Greene disclosed buying the stock twice in 2025 and also purchased shares back in 2021.
UnitedHealth Group (UNH): The health insurance company is a newer addition to Berkshire's portfolio, with the stake first disclosed in the second quarter. It's relatively small for Buffett's standards, representing just 0.5% of the portfolio. Greene bought UnitedHealth shares four times in 2025—twice in August and twice in May.
Beyond these nine shared stocks, Greene and Buffett have another connection: Greene has disclosed buying Berkshire Hathaway shares six times in 2025 and several times in 2024. So she's not just copying some of Buffett's picks—she's actually betting on the man himself.
Two Very Different Approaches
While the overlap in their portfolios is interesting, the way these two investors operate couldn't be more different.
Greene has stated publicly that a portfolio manager handles all of her trades. Earlier this year, she brushed off criticism over the timing of several stock purchases made before President Trump announced a pause on tariffs, which sent stock prices significantly higher.
According to Greene, her portfolio manager didn't have inside information—everything was publicly available, and the potential for a tariff pause wasn't exactly a secret.
"I don't place my buys and sells," Greene said, explaining her agreement with her portfolio manager. "He did a great job. Guess what he did. He bought the dip. And that's what anybody who has financial sense does."
Greene's trades typically fall in the $1,000 to $15,000 range, and many of her purchases focus on large-cap technology companies. Recent disclosures also show she's been buying some stocks at 52-week lows that could be considered value plays.
Buffett, meanwhile, is the ultimate value stock hunter who practices strict buy-and-hold investing. He often holds stock positions for five years or longer, accumulating massive stakes that represent billions of dollars. His approach is patient, methodical, and focused on companies with durable competitive advantages.
It's worth noting that Buffett will step down from his CEO role at Berkshire Hathaway at the end of 2025, which could mean the investment portfolio looks quite different in future years under new leadership.
For now, though, these nine stocks represent common ground between two very different investors—one building small positions with frequent trades, the other holding concentrated positions worth billions. Whether that overlap is coincidence or reflects something fundamental about these companies' appeal is up for debate.
