Tom Gayner is the CEO of Markel Group and has run itsinvestment portfolio for 35 years, beating the index by an astonishing 1.5% pa. This makes him one of the most successful capital allocators in the US stockmarket, yet he is under the radar. He explains why he holds 140 stocks,although the top 40 represent 80% of the value; why there are so few imitators of the insurance/equity and business investment strategy so successfully deployedby Berkshire and Markel; the simple way to analyse an insurance business; what he has learned from being on the boards of Graham Holdings with Warren Buffettand on the Coca Cola Company; and one secret of Warren Buffett’s success which you likely will not have heard before. Tom Gayner is anything but a plodder, but his thoughtful, modest and cautious approach to investing and life makes him a fantastic role model.

Tim Guinness is the founder and Chairman of Guinness Global Investors. He has been in business 5 decades and has been managing money for 44 years. He has built up two firms, the first he sold and the second now runs $11bn. Age 77, he is still thinking about how to grow the business and secure its future. Perhaps controversially, Tim thinks it’s not difficult for activemanagers to beat the index, even today. This was a fascinating discussion with an incredibly experienced and normally under the radar fund manager who is unafraid to challenge consensus thinking.

Nick Train is a seriously thoughtful growth investor with a highly impressive 40 year track record. He invests in eternal franchises and takes a 20 year view. He says his ideal holding period is forever. He was early to recognise that high quality consumer brands were great investments and accordingly his funds significantly outperformed their benchmarks. More recently, the last five years have been less kind and performance has lagged somewhat with weak performance from some of his biggest holdings, notably Diageo, which is down almost 50% from its peak, in a market which has gone up.

Nick has taken this performance to heart and he explains why he has stuck with Diageo and continues to believe it’s as “forever” stock. He also explains his change in strategy to favouring 21st century asset light digital data plays which he sees as even more valuable than his old favourite consumer brands. He is particularly impressed with Rightmove, which I have described in the past as akin to a UK Zillow, and explains his rationale, as well as his enthusiasm for LSEG, RELX and Unilever.

Christopher Tsai is a deeply thoughtful growth investor. He became one of the foremost collectors of the works of Ai Weiwei, recognising their implicit value and deeply studying the artist. His concentrated portfolio reflects his attraction to growth stocks with Tesla his largest position. In our conversation, he explains why he believes Tesla has deep moats across multiple verticals; why he thinks many of the growth stocks in his portfolio have optically inflated valuations as they invest now to create future value; why the second largest position in his portfolio is QXO, with his father, also a famous investor, being one of Brad Jacobs’ original backers; and what he looks for in managers. I am trying to meet more growth investors to understand their strategy better. Christopher’s portfolio is too racy for me, at over a 60x P/E multiple on my estimates when we recorded and probably higher today, but he makes an interesting case for holding long-term compounders.

David Samra has been in the investment business for over 30years. He specialises in international value and has beaten his index by over 4% pa for over 20 years, in a period when traditional value has been doing poorly.

That may be why his fund, which has been closed to new investors for most of the last 14 years, has reached $50bn. In this conversation David explains his focus on four factors: owning good companies, buying them at a discount of at least 30% to intrinsic value, and ensuring they have excellent management and a strong balance sheet.

And he discusses several of his stocks, sharing some impressively detailed knowledge.

Dave Iben is the founder and CIO of Kopernik GlobalInvestors, a $6bn global value investment shop which prides itself on independent thought and is comfortable with contrarian positions.

Steve invited Dave on the podcast because at a recent NewYork conference, Dave was cheerleading that value was back, and Steve wanted to discuss the rationale for his enthusiasm, given value’s massive underperformance in the last 15 years. Luckily Dave was spending the summer in London looking for cheap UK stocks, and they could record in person.

Gary Channon is one of the UK’s better known valueinvestors. He runs a value fund, a closed-end fund and a private equity vehicle. He runs a highly concentrated portfolio. The top 5 positions are over 50%, and he holds no more than 15 stocks.

I asked him on the podcast because he is really thoughtful about his process – he only buys stocks selling for <50% of intrinsic value, and if he can monitor the business performance independently of the company's communications. He is then prepared to hold them for extended periods, as long as they remain cheap.

His framework for evaluating a stock includes parameterslike the depth of work completed and confidence levels, he has instructed his entire research team to become AI experts and he has already seen significant benefits; he thinks AI means sellside analysts will be more or less gone in twoyears; and we talked about his techniques for interviewing management which include spending 4-6 hours preparing for a 1 hour meeting.

Jennifer Wallace is a value investor. She learned her tradefrom a series of luminaries, studying under Bruce Greenwald at Columbia, before going to work for famed value investor Bob Bruce (who used to hang out with Warren Buffett).

Today she is the CIO of Summit Street Capital Management, and only invests in high quality companies with modest leverage when they are super cheap. This means she will often find stocks with issues that are hopefully temporary.

But she has found a winning formula, having delivered a 7.8x return to investors since 2009. Around a quarter of her investee companies have been acquired. She explains why, her rationale for having a 25-30 stock equally-weighted portfolio and why you should not befriend CEOs - "if you want a friend, get a dog”.
