Summarizing the evolution of his investment philosophy from Graham-style cheap stocks to quality businesses.

This quote marks Buffett's philosophical maturation. Early in his career, he followed Benjamin Graham's "cigar butt" approach — buying mediocre companies at deep discounts. But through his partnership with Charlie Munger and lessons from investments like See's Candies, Buffett realized that buying exceptional businesses at reasonable prices and holding them forever generates superior returns. A fair company at a wonderful price may work once, but a wonderful company at a fair price compounds for decades.

Many value investors still obsess over low P/E and P/B ratios, missing businesses with durable competitive advantages trading at reasonable valuations. In today's economy, intangible assets like brand power, network effects, and data moats don't show up well in traditional value metrics. Buffett's shift to "quality at fair price" is more relevant than ever.

Expand your valuation toolkit beyond traditional metrics. Assess competitive advantages: Does the company have pricing power? Do customers willingly pay a premium? Is there a moat that will last 10+ years? Be willing to pay a fair multiple for businesses that compound intrinsic value at high rates. Remember: the best time to buy a wonderful company is when it's temporarily out of favor.
