Most investors assume that earnings growth is the ultimate green light. If a company consistently grows its profits year after year, it must be a great investment—right?
Not according to Warren Buffett. In one of his most famous letters to Berkshire Hathaway shareholders, Buffett dismantled this dangerous myth. He revealed how rapid growth can actually destroy shareholder value in certain businesses, while a modest enterprise that barely grows can turn into an extraordinary compounding machine.
For any investor—especially in high-growth markets like India—cleaning up a portfolio starts with a simple framework. You must categorize businesses into three distinct buckets based on how much capital they require to generate that growth:
1. The Great
A Great business earns exceptionally high returns on invested capital without needing massive amounts of fresh money to grow.
-
The Dynamic: It generates surplus cash flow that can be distributed to owners or reinvested at high rates of return.
-
The Classic Example: See’s Candies. It required minimal incremental capital to expand, turning its modest profits into rivers of free cash flow for Berkshire to deploy elsewhere.
2. The Good
A Good business earns respectable returns on capital, but it requires significant reinvestment to fuel its growth.
-
The Dynamic: It builds genuine long-term value, but much of its profit gets tied up in machinery, working capital, or new facilities rather than flowing out to shareholders as excess cash.
-
The Result: It is a solid, wealth-building investment, but it won’t produce runaway returns unless the capital is deployed with extreme discipline.
3. The Gruesome
A Gruesome business earns poor or inadequate returns on capital—yet it is forced to constantly reinvest just to stay competitive and keep growing.
-
The Dynamic: Growth becomes the enemy. The faster a gruesome business expands, the more cash it consumes, destroying shareholder value with every new dollar invested.
-
The Classic Example: Airlines or capital-heavy manufacturing. They constantly buy expensive assets just to maintain market share, yielding dismal returns on equity.
The Fundamental Question
This brings us to a crucial question every investor must ask before buying a stock:
If two companies both grow their profits at the same 15% rate year after year, are they equally valuable investments?
The answer is a resounding no. The company that achieves 15% growth while reinvesting 10% of its earnings is infinitely more valuable than the company that requires 90% of its earnings just to achieve that same 15%. It isn’t just growth that matters—it’s the capital cost of that growth.
