100 Baggers: Stocks that Return 100-to-1

Our review

Christopher Mayer asked a simple question: what do stocks that multiplied invested money a hundredfold have in common? To answer it he studied the 365 US cases between 1962 and 2014 — from Monster Beverage to Amazon — updating Thomas Phelps's 1972 classic. The patterns he finds are consistent: companies small at the start, with high and sustained returns on capital, the ability to reinvest those returns for decades, owner-operators with aligned incentives, and some competitive advantage protecting the compounding process. But the book's most valuable conclusion is behavioural rather than analytical: nearly every hundred-bagger went through drawdowns of 50% or more along the way, and the difference between capturing the full multiple or a fraction lay in the ability not to sell — what Mayer calls the «coffee-can» approach. It is a thesis book, with survivorship bias as an acknowledged limitation: it studies winners without counting how many identical-profile companies failed. Read with that caution, it is the best modern introduction to very-long-term compounding.

Key takeaways

• The hundred-bagger formula: high return on capital + reinvestment capacity + time — the «twin engine» of earnings growth and multiple expansion.
• Nearly all great compounders suffered drawdowns above 50% along the way; volatility is the price of the multiple.
• Owner-operators (founders or families with meaningful stakes) appear disproportionately among the best cases.
• The study has survivorship bias: it identifies traits of winners, not the success probability of a strategy.

Fact

Mayer analysed 365 US stocks that returned 100-to-1 between 1962 and 2014; the Spanish edition was published by Editorial Tenos in January 2025.
