Warren Buffett
Born
The benchmark. For six decades Buffett wrote Berkshire Hathaway's letter himself, in plain English, as if to his sisters, explaining how insurance float funds the company and why he valued businesses as he did. The candour is what sets them apart: he called the Dexter Shoe purchase his worst deal and owned up to overpaying for Kraft Heinz. Start with any letter from the 1980s or the 2014 fiftieth-anniversary edition. He handed over the chief executive role, and the letter, at the start of 2026.

Charlie Munger
Born
Munger's letters to shareholders of Wesco Financial, the Berkshire affiliate he chaired, are shorter and blunter than Buffett's and less widely read, which is a shame. He set out exactly how Wesco's assets should be valued and repeatedly told shareholders the stock was not worth more than that, which few chairmen ever do. The 2009 letter on the financial crisis is a good starting point.

John C. Bogle
Born
As Vanguard's chairman, Bogle used the annual report letters to make one argument over and over, that costs eat returns, and to criticise his own industry's fees while doing it. Because Vanguard is owned by its funds, his letters spoke to investors as the owners, and the consistency is striking: what he wrote in the 1970s about index funds is what he was still writing decades later, and the evidence moved his way.

Prem Watsa
Born
Watsa has written Fairfax Financial's letter since the 1980s, opening each with a table of book value growth so readers can judge him on one number. He is unusually open about bets that went against him, such as the deflation hedges and stock market shorts that cost Fairfax heavily in the 2010s, and explains why he held them. Reading the letters in sequence is a good test of consistency, because the positions and their outcomes are all there in print.

Jeff Bezos
Born
Bezos's first letter, in 1997, told Amazon shareholders the company would put long-term market leadership ahead of short-term profits, and he reattached it to every letter he wrote until stepping down as chief executive in 2021. That is the clearest consistency test on this list, and Amazon broadly did what it said. Later letters explained ideas like Day 1 thinking and two-pizza teams, and admitted failures such as the Fire Phone as the price of experimenting.

Jamie Dimon
Born
Dimon's JPMorgan Chase letters are long, sometimes very long, but they are organised and specific: capital, risk, each business line, then his views on regulation and the economy. The letter after the 2012 London Whale trading loss addressed it head-on, accepting blame and setting out which risk controls had failed and what changed. The policy sections can read as lobbying, so separate the explanation of the bank from the advocacy.

Reed Hastings
Born
Under Hastings, Netflix swapped the usual polished quarterly release for a plain letter to shareholders, followed by a recorded interview, setting out subscriber numbers, forecasts and the reasoning behind big bets on streaming and original shows. It also missed its own forecasts in public and said so. His 2011 apology over the botched Qwikster split was a model of owning a mistake, even if the decision itself was poor.

Terry Smith (businessman)
Smith's annual letter to Fundsmith investors restates the same three-part strategy every year, buy good companies, do not overpay, do nothing, and then grades the fund against it with tables and plain explanations. Its value for this list is the later letters, written during years of underperformance against the index, where he explains why he has not changed course rather than hiding the numbers. Writing quality and fund performance are two separate questions here.

Seth Klarman
Born
Klarman's letters to clients of Baupost, a private fund, are not public, but copies have circulated for years because they explain value investing so plainly: why holding cash can be the right call, how he thinks about risk rather than volatility, and when he got things wrong. Treat them as client letters rather than shareholder reports, and note that reading them depends on leaked copies.

Howard Marks (investor)
Marks writes memos to Oaktree's clients rather than shareholder letters, and he has published them openly since 1990. They earn a place for clarity: each takes one idea, such as market cycles, risk or the limits of forecasting, and explains it with examples. His January 2000 memo on the technology bubble was written just before the crash, which is about as good a consistency check as a writer can pass.

Larry Fink
Born
Fink is here as a useful contrast. His annual letters, addressed to the chief executives of companies BlackRock invests in and since 2024 also to its own shareholders, are clearly written and widely read. On consistency, though, the record is mixed: heavy emphasis on climate and stakeholder capitalism around 2020 was toned down after political backlash. Reading several years together shows how clarity and steadiness can come apart.

Greg Abel
Born
Abel's first Berkshire letter, published in February 2026, had the hardest act on this list to follow. It kept Buffett's plain style, explained that he would not rush to spend the huge cash pile or start paying dividends, and called the Kraft Heinz stake a disappointment. One letter is not a record, so this entry is provisional, but the early signs are that the habit of candour will continue.
