Tom Gayner joined Markel Corporation in 1990 as the company's chief investment officer. Markel, at the time, was primarily a specialty insurance company based in Richmond, Virginia. In his capacity as CIO, Gayner assumed responsibility for managing the firm's investment portfolio, which consisted largely of the float generated by Markel's insurance operations — premiums collected before claims are paid out. This float provided a pool of capital available for investment, a financial dynamic that Gayner recognized as structurally advantageous and one that he has frequently discussed in public remarks.<ref name="barrons" /> | |||
Over the ensuing decades, Gayner built a concentrated equity portfolio focused on companies he assessed as possessing durable competitive advantages, competent management, and the ability to reinvest capital at attractive rates of return. His approach to selecting investments has been described as patient and long-term oriented, consistent with the principles of value investing as articulated by Benjamin Graham and later refined by Warren Buffett and Charlie Munger.<ref name="themarket" /> | |||
=== Investment Philosophy === | === Investment Philosophy === | ||
Gayner | Gayner's investment philosophy draws directly from the tradition of value investing that originated with Benjamin Graham and David Dodd at [[Columbia Business School]] in the late 1920s and was codified in their 1934 text ''[[Security Analysis (book)|Security Analysis]]''. Graham advocated purchasing securities trading below their [[intrinsic value]], a concept he termed the "[[margin of safety]]."<ref>{{cite web |title=Berkshire Hathaway Chairman's Letter, 1989 |url=http://www.berkshirehathaway.com/letters/1989.html |publisher=Berkshire Hathaway |access-date=2026-02-24}}</ref> While Graham's original framework focused on quantitative measures such as low price-to-earnings ratios, low price-to-book ratios, and high dividend yields, Buffett evolved the approach to emphasize the quality of the underlying business — seeking, as he described it, "an outstanding company at a sensible price" rather than a mediocre company at a bargain price.<ref>{{cite news |title=The New Mr. Buffetts |url=https://money.cnn.com/magazines/fortune/fortune_archive/2004/06/28/374411/ |work=Fortune |date=June 28, 2004 |access-date=2026-02-24}}</ref> | ||
Gayner has acknowledged this lineage explicitly. In a 2025 interview with ''The Market'', he stated that "Warren Buffett and Charlie Munger laid out the playbook," referencing their influence on his approach to both investing and corporate management.<ref name="themarket" /> In the same interview and in other public appearances, Gayner has described his investment criteria as focusing on four attributes: companies with profitable businesses that earn good returns on capital; management teams that possess both talent and integrity; businesses with reinvestment opportunities and room for growth; and availability at a reasonable price.<ref name="themarket" /> | |||
Gayner | A defining characteristic of Gayner's approach is his avoidance of speculative or momentum-driven investment strategies. In a November 2025 interview at the Library of Mistakes, Gayner articulated his view that avoiding "hot stocks" leads to better long-term investment returns. He emphasized that enduring investment success comes not from following popular trends or attempting to identify the next high-growth sensation, but from a disciplined commitment to owning businesses with sound fundamentals over extended periods.<ref name="hotstocks">{{cite web |title=Tom Gayner: Why Avoiding "Hot Stocks" Leads to Better Long-Term Returns |url=https://acquirersmultiple.com/2025/11/tom-gayner-why-avoiding-hot-stocks-leads-to-better-long-term-returns/ |publisher=The Acquirer's Multiple |date=November 25, 2025 |access-date=2026-02-24}}</ref> | ||
This philosophy is reflected in the construction and management of Markel's equity portfolio. As reported in the company's Q3 2025 13F filing, the portfolio was concentrated, with the top ten holdings representing a significant portion of the total $12.32 billion in equity investments. The filing also revealed selective trimming of positions and full exits from certain holdings, indicating an ongoing process of portfolio refinement consistent with Gayner's stated emphasis on discipline and selectivity.<ref name="acquirers13f" /> | |||

Gayner's portfolio management at Markel has been characterized by relatively low turnover and a preference for holding positions over many years.

=== | === Expansion of Markel and the "Baby Berkshire" Model === | ||
Under Gayner's leadership, first as CIO and subsequently as CEO, Markel has evolved from a specialty insurance company into a diversified holding company. This transformation has involved not only the management of a large public equity portfolio but also the acquisition of wholly owned businesses across a range of industries. The corporate structure — combining insurance operations that generate float, a public equity portfolio, and a collection of operating businesses — closely mirrors the model employed by Berkshire Hathaway, prompting financial commentators and analysts to refer to Markel as "Baby Berkshire."<ref name="barrons" /> | |||
Gayner has addressed this comparison directly. In a 2025 interview with ''Barron's'', he was described as "a long-time disciple of Buffett's and Berkshire" who has "modeled Markel Group to a degree after that company."<ref name="barrons" /> In his interview with ''The Market'' the same year, Gayner elaborated on how Buffett and Munger's principles have informed not just his investment decisions but the broader corporate strategy at Markel, including the approach to acquisitions, capital allocation, and organizational culture.<ref name="themarket" /> | |||
The company's transition from Markel Corporation to Markel Group reflects this broader strategic evolution, signaling the firm's identity as a diversified holding company rather than a pure-play insurance operation. Gayner's role expanded accordingly — from managing the investment portfolio to overseeing the entire enterprise, including its insurance underwriting operations, its venture capital and private equity-style investments in wholly owned subsidiaries, and its public equity holdings. | |||
=== Role as CEO === | |||
Gayner was named co-chief executive officer of Markel Corporation in 2016, sharing the role initially before eventually assuming sole leadership of the company. In this capacity, he has been responsible for the overall strategic direction of Markel Group, encompassing its three primary business segments: insurance, investments, and Markel Ventures, the division that houses the company's wholly owned operating businesses. | |||
As CEO, Gayner has continued to apply the same investment principles that guided his work as CIO. He has emphasized the importance of long-term thinking, decentralized management of operating businesses, and a culture of integrity and accountability. His management style, as described in interviews, reflects a preference for simplicity and transparency — qualities he associates with the Berkshire Hathaway model that has influenced his career.<ref name="barrons" /><ref name="themarket" /> | |||
== Investment Approach and Intellectual Influences == | |||
== | Gayner's intellectual framework is situated firmly within the tradition of value investing as it has evolved from the foundational work of Benjamin Graham and David Dodd. Graham and Dodd's 1934 text ''Security Analysis'' established the conceptual apparatus for analyzing securities based on fundamental factors rather than market sentiment or price momentum. Graham introduced the concept of intrinsic value — the true worth of a security based on its underlying business fundamentals — and the margin of safety, defined as the difference between a security's market price and its intrinsic value.<ref>{{cite web |title=Value Investing vs. Growth Investing |url=https://www.fidelity.com/learning-center/trading-investing/trading/value-investing-vs-growth-investing |publisher=Fidelity Investments |access-date=2026-02-24}}</ref> | ||
Warren Buffett, Graham's most prominent student, subsequently refined this approach by shifting emphasis from purely quantitative screening criteria — such as low price-to-earnings or low price-to-book ratios — to qualitative assessments of business quality, competitive positioning, and management capability. This evolution, often described as the transition from "cigar butt" investing to ownership of high-quality businesses, has been a defining influence on Gayner's approach.<ref name="themarket" /> | |||
Gayner has frequently cited both Buffett and Munger as central to his intellectual development. Munger, in particular, contributed to the evolution of value investing by emphasizing the importance of mental models drawn from multiple disciplines, the dangers of psychological biases, and the value of patience in capital allocation. Gayner's stated focus on management integrity, reinvestment opportunities, and reasonable valuations reflects the synthesis of Graham's quantitative rigor with the Buffett-Munger emphasis on qualitative business analysis.<ref name="themarket" /> | |||
The academic literature on value investing has provided empirical support for the approach. Research by Eugene Fama and Kenneth French, published in ''The Journal of Finance'' in 1992, documented that stocks with high book-to-market ratios (a proxy for value stocks) tended to outperform growth stocks over extended periods.<ref>{{cite web |title=The Cross-Section of Expected Stock Returns |url=http://ideas.repec.org/a/bla/jfinan/v47y1992i2p427-65.html |publisher=IDEAS/RePEc |access-date=2026-02-24}}</ref> Subsequent research, including a 1997 study also published in ''The Journal of Finance'', further examined the relationship between value characteristics and stock returns.<ref>{{cite web |title=Value versus Growth: The International Evidence |url=http://ideas.repec.org/a/bla/jfinan/v52y1997i2p875-83.html |publisher=IDEAS/RePEc |access-date=2026-02-24}}</ref> Earlier empirical work by S.

Gayner's investment practice aligns with these empirical findings while also incorporating the qualitative judgment that characterizes the Buffett-Munger school.

Thomas Saunders Gayner is an American business executive and investor who serves as the chief executive officer of Markel Group (formerly Markel Corporation), a holding company headquartered in Richmond, Virginia, with roots in specialty insurance. Gayner first joined Markel in 1990 as chief investment officer, a role in which he built and managed a multi-billion-dollar equity portfolio over more than three decades. He was named co-chief executive officer in 2016 and assumed the sole CEO position thereafter. Under his stewardship, Markel has expanded beyond its insurance origins into a diversified holding company with significant investments in both public equities and wholly owned businesses — a corporate structure that has drawn frequent comparisons to Berkshire Hathaway, the conglomerate led by Warren Buffett.[1] Gayner is a practitioner of value investing, the investment philosophy rooted in the teachings of Benjamin Graham and David Dodd, and he has credited Buffett and Charlie Munger as primary influences on his approach to capital allocation.[2] His investment philosophy emphasizes long-term ownership of high-quality businesses, avoidance of speculative trends, and a disciplined approach to portfolio construction. As of the third quarter of 2025, Markel Group's equity portfolio under Gayner's direction was valued at approximately $12.32 billion.[3]
Career
Joining Markel Corporation
Tom Gayner joined Markel Corporation in 1990 as the company's chief investment officer. Markel, at the time, was primarily a specialty insurance company based in Richmond, Virginia. In his capacity as CIO, Gayner assumed responsibility for managing the firm's investment portfolio, which consisted largely of the float generated by Markel's insurance operations — premiums collected before claims are paid out. This float provided a pool of capital available for investment, a financial dynamic that Gayner recognized as structurally advantageous and one that he has frequently discussed in public remarks.[1]
Over the ensuing decades, Gayner built a concentrated equity portfolio focused on companies he assessed as possessing durable competitive advantages, competent management, and the ability to reinvest capital at attractive rates of return. His approach to selecting investments has been described as patient and long-term oriented, consistent with the principles of value investing as articulated by Benjamin Graham and later refined by Warren Buffett and Charlie Munger.[2]
Investment Philosophy
Gayner's investment philosophy draws directly from the tradition of value investing that originated with Benjamin Graham and David Dodd at Columbia Business School in the late 1920s and was codified in their 1934 text Security Analysis. Graham advocated purchasing securities trading below their intrinsic value, a concept he termed the "margin of safety."[4] While Graham's original framework focused on quantitative measures such as low price-to-earnings ratios, low price-to-book ratios, and high dividend yields, Buffett evolved the approach to emphasize the quality of the underlying business — seeking, as he described it, "an outstanding company at a sensible price" rather than a mediocre company at a bargain price.[5]
Gayner has acknowledged this lineage explicitly. In a 2025 interview with The Market, he stated that "Warren Buffett and Charlie Munger laid out the playbook," referencing their influence on his approach to both investing and corporate management.[2] In the same interview and in other public appearances, Gayner has described his investment criteria as focusing on four attributes: companies with profitable businesses that earn good returns on capital; management teams that possess both talent and integrity; businesses with reinvestment opportunities and room for growth; and availability at a reasonable price.[2]
A defining characteristic of Gayner's approach is his avoidance of speculative or momentum-driven investment strategies. In a November 2025 interview at the Library of Mistakes, Gayner articulated his view that avoiding "hot stocks" leads to better long-term investment returns. He emphasized that enduring investment success comes not from following popular trends or attempting to identify the next high-growth sensation, but from a disciplined commitment to owning businesses with sound fundamentals over extended periods.[6]
This philosophy is reflected in the construction and management of Markel's equity portfolio. As reported in the company's Q3 2025 13F filing, the portfolio was concentrated, with the top ten holdings representing a significant portion of the total $12.32 billion in equity investments. The filing also revealed selective trimming of positions and full exits from certain holdings, indicating an ongoing process of portfolio refinement consistent with Gayner's stated emphasis on discipline and selectivity.[3]
Portfolio Management and Notable Transactions
Gayner's portfolio management at Markel has been characterized by relatively low turnover and a preference for holding positions over many years. However, he has demonstrated a willingness to exit positions when his assessment of a company's prospects changes or when valuations no longer meet his criteria.
In the third quarter of 2025, Gayner made a notable strategic decision to fully exit Markel's position in 3M Co, a diversified industrial conglomerate. This move, disclosed in the quarterly 13F filing, was part of broader portfolio adjustments that also included selective trimming of other positions.[7]
In the fourth quarter of 2025, Gayner continued to refine the portfolio, fully exiting the position in FedEx Corp among other adjustments. These decisions reflected an ongoing evaluation process in which holdings are measured against Gayner's investment criteria and capital is reallocated accordingly.[8]
As of early 2026, Markel Gayner Corp's portfolio continued to be actively monitored by investment research platforms, with detailed breakdowns of sector allocations, holding histories, and performance metrics publicly available through regulatory filings.[9][10]
Expansion of Markel and the "Baby Berkshire" Model
Under Gayner's leadership, first as CIO and subsequently as CEO, Markel has evolved from a specialty insurance company into a diversified holding company. This transformation has involved not only the management of a large public equity portfolio but also the acquisition of wholly owned businesses across a range of industries. The corporate structure — combining insurance operations that generate float, a public equity portfolio, and a collection of operating businesses — closely mirrors the model employed by Berkshire Hathaway, prompting financial commentators and analysts to refer to Markel as "Baby Berkshire."[1]
Gayner has addressed this comparison directly. In a 2025 interview with Barron's, he was described as "a long-time disciple of Buffett's and Berkshire" who has "modeled Markel Group to a degree after that company."[1] In his interview with The Market the same year, Gayner elaborated on how Buffett and Munger's principles have informed not just his investment decisions but the broader corporate strategy at Markel, including the approach to acquisitions, capital allocation, and organizational culture.[2]
The company's transition from Markel Corporation to Markel Group reflects this broader strategic evolution, signaling the firm's identity as a diversified holding company rather than a pure-play insurance operation. Gayner's role expanded accordingly — from managing the investment portfolio to overseeing the entire enterprise, including its insurance underwriting operations, its venture capital and private equity-style investments in wholly owned subsidiaries, and its public equity holdings.

In this capacity, he has been responsible for the overall strategic direction of Markel Group, encompassing its three primary business segments: insurance, investments, and Markel Ventures, the division that houses the company's wholly owned operating businesses.

His management style, as described in interviews, reflects a preference for simplicity and transparency — qualities he associates with the Berkshire Hathaway model that has influenced his career.[1][2]
Investment Approach and Intellectual Influences
Gayner's intellectual framework is situated firmly within the tradition of value investing as it has evolved from the foundational work of Benjamin Graham and David Dodd. Graham and Dodd's 1934 text Security Analysis established the conceptual apparatus for analyzing securities based on fundamental factors rather than market sentiment or price momentum. Graham introduced the concept of intrinsic value — the true worth of a security based on its underlying business fundamentals — and the margin of safety, defined as the difference between a security's market price and its intrinsic value.[11]
Warren Buffett, Graham's most prominent student, subsequently refined this approach by shifting emphasis from purely quantitative screening criteria — such as low price-to-earnings or low price-to-book ratios — to qualitative assessments of business quality, competitive positioning, and management capability. This evolution, often described as the transition from "cigar butt" investing to ownership of high-quality businesses, has been a defining influence on Gayner's approach.[2]
Gayner has frequently cited both Buffett and Munger as central to his intellectual development. Munger, in particular, contributed to the evolution of value investing by emphasizing the importance of mental models drawn from multiple disciplines, the dangers of psychological biases, and the value of patience in capital allocation. Gayner's stated focus on management integrity, reinvestment opportunities, and reasonable valuations reflects the synthesis of Graham's quantitative rigor with the Buffett-Munger emphasis on qualitative business analysis.[2]
The academic literature on value investing has provided empirical support for the approach.

His avoidance of speculative positions and emphasis on long-term holding periods are consistent with the evidence suggesting that patient, fundamentals-based investing tends to produce favorable outcomes relative to more active or trend-following strategies.[6]
Recognition
Gayner's track record at Markel has attracted significant attention from the financial media and the investment community. He is regularly profiled in major financial publications and is a sought-after speaker at investment conferences and educational events.
In August 2025, Barron's published a feature profile describing Gayner's approach to running Markel Group and drawing explicit parallels between his strategy and that of Warren Buffett at Berkshire Hathaway. The article characterized Gayner as someone who follows "the Buffett Playbook" and noted the success of Markel's diversified holding company model under his leadership.[1]
The Market, a Swiss financial publication, published an extended interview with Gayner in May 2025 in which he discussed his investment philosophy, his views on capital allocation, and the influence of Buffett and Munger on his thinking.[2]
Gayner's portfolio decisions are tracked by investment research platforms including GuruFocus, which maintains detailed records of Markel Gayner Corp's holdings, sector allocations, and transaction history based on quarterly 13F filings with the U.S. Securities and Exchange Commission.[9][10] His quarterly filing disclosures are also regularly analyzed by financial media outlets including Yahoo Finance and The Acquirer's Multiple, which publish detailed commentary on his portfolio adjustments.[7][8][3]
Gayner has been invited to speak at venues including the Library of Mistakes, where his November 2025 appearance focused on the merits of long-term investing and the pitfalls of chasing popular market trends.[6]
Legacy
Tom Gayner's career at Markel Group represents one of the most sustained applications of value investing principles within a corporate setting outside of Berkshire Hathaway itself. Over more than three decades, he has built and managed an equity portfolio that grew to exceed $12 billion in value while simultaneously helping to transform Markel from a specialty insurance company into a diversified holding company.[3][1]
The "Baby Berkshire" designation that has attached itself to Markel under Gayner's leadership reflects both the structural similarities between the two companies and the philosophical alignment between Gayner and his acknowledged mentors, Buffett and Munger. Gayner has been open about the degree to which Berkshire's model has informed Markel's corporate development, and the success of that approach has served as evidence that the principles of long-term, fundamentals-based investing and decentralized corporate management are replicable beyond Berkshire itself.[1][2]

The continued monitoring of his portfolio decisions by research platforms and financial media reflects his standing as a figure whose investment actions are considered informative by professional and individual investors alike. Markel Group's evolution under his stewardship serves as a case study in the application of value investing principles to corporate strategy and capital allocation at scale.[9][3]
