100 Baggers: Stocks That Return 100-to-1 and How to Find Them, in detail
Christopher Mayer built this book on research conducted earlier by Thomas Phelps, whose 1972 book 100 to 1 in the Stock Market studied stocks that returned one hundred times their purchase price. Mayer updated Phelps's work by studying every US-listed stock that returned 100-to-1 between 1962 and 2014 — identifying 365 stocks in total — and asked what they had in common. The answer structures the book.
The common characteristics of 100-baggers cluster around a few themes. First, exceptional business quality: the companies in the study tended to have high returns on equity, strong competitive positions, and the ability to reinvest earnings at high rates of return for extended periods. Second, growth: both in revenue and earnings, over many years. Third, valuation at purchase: while overpaying was possible, most 100-baggers were purchased at reasonable valuations relative to their eventual earnings power. Fourth, and most important, time: holding periods of ten, twenty, or thirty years. The math of compounding requires time, and most investors sell far too early, often at three or five times their purchase price, missing the vast majority of the eventual return.
Mayer draws extensively on examples — Monster Beverage, Kansas City Southern, Gillette, Sears (before its decline), and many lesser-known businesses — to illustrate what exceptional compounding looks like in practice. He is honest that identifying these stocks in advance is genuinely hard. The characteristics he describes are visible clearly only in hindsight. Many businesses that looked like 100-baggers at year five were not at year twenty.
The book's most practical contribution is probably what Mayer calls the "coffee can portfolio" concept, borrowed from Robert Kirby: buy a set of high-quality businesses and do nothing with them for a decade. The constraint is that you cannot add or remove holdings. The forced inaction tends to outperform active management because it eliminates the most common errors — taking profits too early, cutting losses that recover, and churning into whatever looks good this year.
100 Baggers is most useful as a mental model, not a stock-picking algorithm. Mayer is not promising that following his framework will produce 100-baggers. He is arguing that understanding what they required — business quality, growth, time, patience — changes how an investor should think about portfolio construction and time horizon.
The big ideas
- 1.
The single most important ingredient in producing 100-baggers is time. Most investors sell long before the compounding has done its work — often at 3x or 5x — forfeiting the next 20x.
- 2.
High returns on equity, reinvested at high rates over long periods, are the mathematical engine behind every 100-bagger. The business quality must be exceptional and durable.
- 3.
Owner-operators — founders or major shareholders who run the business — outperform hired management in the 100-bagger data. Skin in the game aligns incentives over long periods.
