Warren Buffett’s Ground Rules

I’ve read a number of books on Warren Buffett over the years, covering both his life and his investment philosophy, particularly during his time at Berkshire Hathaway. Ground Rules may now be one of my favourites amongst them.

The book is built around Buffett’s partnership letters from his time running Buffett Partnership Limited, offering a window into his thinking before he became the figure most people associate with Berkshire today. It provides insight into the principles he applied during some of his most successful investing years, when his capital, whilst still significant by an average person’s standards, was far smaller than it would later become. This allowed him to be far more nimble, seeking out opportunities that wouldn’t have been possible at the scale he eventually reached.

Each chapter is structured around a core theme, followed by a curated selection of partnership letters, and concludes with a section titled “Compounding Wisdom.” This format works well, giving you both the original source material and a distilled interpretation of the key ideas.

What stands out is not just Buffett’s approach to investing, but how he managed the partnership itself. There’s a strong emphasis on alignment of incentives, transparency with partners and, ultimately, how he chose to wind down the fund. Even in that process, he provided guidance on alternative investment managers for his partners, with a running theme evident throughout on the level of integrity he maintained in his management and relationships.  

Whilst many of these traits are well known, it’s different seeing them expressed directly through his own words, before he became a widely recognised figure in the investing world.

The structure also makes the book pretty flexible to digest. You can read it sequentially, dip into specific chapters for reference, or choose between focusing on the core themes or diving deeper into the full letters. For some the overview may be sufficient whereas for others they may want to read the source material and draw their own interpretations.

I recently reviewed The University of Berkshire Hathaway and said it deserved a place in any investor’s library. Whilst I’ll try not to make strong recommendations in such close proximity, Ground Rules arguably earns that place even more so, given the particular stage of Buffett’s career it draws from.

Who’s It For?

These are very much ground rules for investing rather than in general.

Whilst there are broader lessons around integrity and how Buffett managed relationships, if you have no interest in investing this is unlikely to be for you. For anyone interested in long term investing, compounding and understanding the principles behind sustained success, there’s a great deal of value here.
