Warren Buffett’s approach to investing has evolved significantly over the decades, and his remarks during the 2003 Berkshire Hathaway Annual Meeting offer a glimpse into that transformation.
What began as a strict adherence to Benjamin Graham’s quantitative approach to investing eventually shifted toward a more nuanced understanding of business quality—largely influenced by his long-time partner, Charlie Munger.
Buffett acknowledged the profound impact of Graham’s teachings on his early investment career, stating, “I had learned investment, and got enormous benefit out of that learning, from a fellow who concentrated on the quantitative aspects, Ben Graham.”
Graham’s focus on numbers, particularly undervalued stocks, led to the classic “cigar butt” strategy—finding companies that still had a few good puffs left in them. Graham believed that while qualitative factors had value, “the quantitative works fine, so why try harder?”
This school of thought worked well in many cases, but Munger challenged Buffett to see beyond the numbers. Buffett admitted, “Charlie emphasized the qualitative much more than I did when I started.”
This shift in thinking led to a fundamental change in their investment philosophy: prioritizing high-quality businesses with durable competitive advantages rather than simply buying undervalued companies regardless of their long-term potential.
As Buffett famously put it, “It makes more sense to buy a wonderful business at a fair price, than a fair business at a wonderful price.”
This transformation did not happen overnight. Buffett described the process as gradual, saying, “There was not a strong, bright red line of demarcation where we went from cigar butts to wonderful companies.”
Instead, it was a learning experience refined through decades of observing businesses and market behavior. He acknowledged that while there is still money to be made in the traditional value investing approach, the real wealth-building opportunities lie in owning “a collection of wonderful companies.”
Buffett’s remarks underscore an essential lesson for investors: rigid adherence to one philosophy can limit potential gains. While Graham’s methods laid a strong foundation, Munger’s influence broadened Buffett’s perspective, allowing Berkshire Hathaway to become one of the greatest investment success stories in history.
The lesson is clear—investing is not just about numbers; it’s about recognizing and owning truly exceptional businesses for the long haul.
