This audio edition features Warren Buffett’s July 1961 Semi Annual Letter to the partners of Buffett Partnership Ltd, offering a clear view into the operational evolution and investment discipline behind his growing partnerships.

Buffett opens by explaining his decision to communicate with partners twice a year, reinforcing transparency and alignment. He reports that during the first half of 1961 the Dow Jones Industrial Average rose about 13 percent, while the partnership delivered slightly better results. Despite this, Buffett cautions against overemphasizing short term comparisons and reiterates that a conservative investment style may lag during speculative market advances.

A central theme of the letter is the planned consolidation of all existing partnerships into a single entity at year end. Buffett details how this merger will introduce a revised profit sharing structure, permit monthly withdrawals, and ensure that the new partnership fully represents his personal investment in marketable securities.

The letter concludes with practical operational updates, including a 25,000 dollar minimum investment for new partners and estimated total assets of approximately 4 million dollars. Together, these details illustrate the increasing scale, professionalism, and long term orientation of Buffett’s early investment operation.

This extended audio edition presents a detailed exploration of the February 2025 article by Michael J. Mauboussin and Dan Callahan, CFA, focusing on the central role of expected value in investment decision making. The episode explains why understanding both probabilities and payoffs is essential for long term success, highlighting the distinction between the observable price of a security and its far more complex underlying value.Key concepts include the Babe Ruth effect, which illustrates how the magnitude of gains can outweigh the frequency of losses; the impact of behavioral challenges such as loss aversion, overprecision, and confirmation bias; and the importance of using base rates and quantified expectations to improve forecasting accuracy. The audio also compares how different asset classes such as public equities and venture capital exhibit distinct return distributions, shaping their risk reward profiles. Principles like the Kelly criterion and margin of safety are discussed as tools to guide portfolio sizing and decision making in non ergodic environments where outcomes do not naturally average out over time.Explore more episodes and playlists from ValueLettershttps://www.youtube.com/@ValueLetters/playlistsSource:https://www.morganstanley.com/im/publication/insights/articles/article_probabilitiesandpayoffs.pdf#MichaelMauboussin #DanCallahan #ExpectedValue #ProbabilitiesAndPayoffs #BehavioralFinance #InvestmentThinking #KellyCriterion #MarginOfSafety #ValueInvesting #DecisionMaking #RiskManagement #ReturnDistributions
