Super Investor #34 in our series is Bill Miller – the legendary portfolio manager who beat the S&P 500 for 15 straight years and blended value with growth.
For decades, Bill Miller was the face of value investing at Legg Mason, but unlike traditionalists, he broke many of the “rules” by owning stocks others considered too expensive. His unconventional style, grounded in deep analysis and long-term conviction, produced one of the most remarkable streaks in investing history.
This article explores Bill Miller’s background, investing philosophy, most famous stock picks, and what lessons buy-and-hold investors can take away from his storied career.
Bill Miller: Early Life and Background
Influences & Education
Bill Miller was born in 1950 and grew up in Florida. He graduated with honors from Washington and Lee University with a degree in economics and later earned a master’s degree in philosophy from Johns Hopkins University. This blend of analytical thinking and philosophical depth would later shape his contrarian investing approach.
His fascination with markets started early, but it was value investing legends like Benjamin Graham and Warren Buffett who influenced his early thought process. However, Miller didn’t stop at traditional value metrics—he challenged them.
Career Beginnings
Miller joined Legg Mason Capital Management in 1981 and quickly rose through the ranks. By 1990, he was managing the Legg Mason Value Trust (LMVTX), where he began applying his unique blend of valuation metrics and forward-looking analysis.
It wasn’t long before he made headlines for his bold positions and consistent market outperformance.
📊 Investment Philosophy & Strategy of Bill Miller
Core Principles
Bill Miller is best known for pushing the boundaries of what constitutes a “value” stock. His core belief is simple yet radical:
“Value is determined by how far a stock’s current price is below its intrinsic value, regardless of whether it’s a ‘growth’ or ‘value’ company.”
In other words, he believed growth companies can be value stocks if their long-term cash flow potential is underestimated by the market.
Investment Approach
His investing process focused on:
-
Discounted Cash Flow (DCF) analysis to determine intrinsic value
-
Contrarian thinking—buying what others hate, if fundamentals justify it
-
Long holding periods to let fundamentals play out
-
Concentrated bets when conviction is high
Notable Techniques
Bill Miller often defied the Efficient Market Hypothesis (EMH), arguing that investors’ emotional biases created opportunities for long-term thinkers. He combined data analysis with philosophical insight to recognize mispriced assets—often in tech, which was unconventional for value investors.
He described his approach as a mix of value and growth with a contrarian edge, a strategy that placed him apart from many of his peers.
