Summary
The Single Best Investment is Lowell Miller's extended argument for dividend growth investing as the most reliable long-term wealth-building strategy available to individual investors. The single best investment of the title is not a specific stock or fund but a class of investment: high-quality companies with a track record of consistently growing their dividends. Miller, a professional money manager, makes the case that dividend growth combines the total return potential of equities with the income certainty of bonds, and does so in a way that compounds powerfully over time.
The conceptual core is what Miller calls the three components of return: the current dividend yield, the rate of dividend growth, and any change in the price-to-earnings multiple investors are willing to pay. He argues that the first two components are more predictable and controllable than the third, which is largely at the mercy of sentiment. A company that currently yields 3% and grows its dividend at 7% annually produces a 10% nominal return even if the P/E multiple never changes. Over decades, this compounds into substantial wealth, and the growing dividend income provides a cushion during market downturns that pure capital appreciation strategies lack.
Miller distinguishes his approach from the high-yield trap — the mistake of chasing the highest current yield without regard for whether the dividend is sustainable and growing. High current yield often signals financial stress or a business in decline. The companies Miller targets are durable consumer franchises, utilities, and established industrials with decades of dividend history, low payout ratios relative to earnings, and strong free cash flow. The strategy is explicitly conservative and long-term, built for investors who want to sleep at night rather than maximize short-term performance.
The book shows its age in some details — it predates the explosion of index funds and ETFs — but the underlying logic remains intact. Dividend growth investing has since been validated by decades of additional data and formalized in academic research on factor investing. For investors drawn to income rather than pure capital appreciation, Miller's framework remains a useful and honest account of why the strategy works and what it requires in terms of patience.

Key takeaways
- 1.
Dividend growth investing targets companies that consistently raise their dividends — not just high-yielding companies, which can signal financial distress.
- 2.
Total return from a dividend growth stock has three components: current yield, dividend growth rate, and multiple expansion. The first two are more predictable than the third.
- 3.
A portfolio of growing dividend payers provides rising income over time, helping investors stay invested during market downturns when capital-only investors panic.
- 4.
The payout ratio — dividends as a percentage of earnings — is a key indicator of sustainability. Low payout ratios leave room for dividend growth even in difficult years.
- 5.
Compounding dividend reinvestment dramatically amplifies long-term returns. The number of shares grows even as the dividend per share grows.
- 6.
The high-yield trap is real: chasing the highest current yield often leads to companies with deteriorating businesses and dividend cuts.
- 7.
Free cash flow, not reported earnings, is the true measure of a company's ability to sustain and grow dividends.
- 8.
Dividend growth investing is a patient strategy. Most of the compounding happens in the later years, which means investors who exit early capture only a fraction of the total benefit.

- 1.
Miller argues that dividend growth is the single best investment for most individuals. What assumptions does that conclusion rest on, and which do you find most debatable?
- 2.
How does thinking about total return in three components — yield, growth, and multiple expansion — change how you evaluate a potential stock purchase?
- 3.
Miller warns against the high-yield trap. Have you encountered investments that looked attractive on yield alone but turned out to be problematic? What were the warning signs?
- 4.
The strategy requires patience over decades. What psychological challenges does a long-term dividend focus introduce, and how does Miller address them?
- 5.
How does dividend income change investor behavior during market downturns compared to a portfolio that produces no income?
- 6.
Miller's framework predates the rise of index funds. Given the evidence on passive investing, where does dividend growth stock-picking still make sense?
- 7.
Free cash flow is described as more reliable than reported earnings for assessing dividend sustainability. Why might the two diverge significantly?
- 8.
The book focuses heavily on consumer staples, utilities, and industrials. What does that bias imply about where dividend growth investing works and where it doesn't?
- 9.
How should a young investor in the accumulation phase think about dividend investing differently than a retiree who needs current income?
- 10.
Miller argues that rising dividends provide an inflation hedge over time. Is that argument convincing, and how does it compare to other inflation hedges like real estate or TIPS?
- 11.
What does the sustained dividend growth record of companies like Johnson & Johnson or Coca-Cola tell us about what kind of business quality the strategy actually selects for?
Themes
Frequently asked questions
-
Is The Single Best Investment worth reading?
Yes, for investors interested in dividend-focused strategies. Miller explains the logic clearly and honestly, including the limitations. The book is more conceptual than technical and does not require accounting knowledge. Some chapter-level detail is dated but the core framework holds up well.
-
How long does this book take to read?
Around three to four hours. It reads at a pace similar to most investing books aimed at individuals, with some denser chapters on mechanics that reward slower reading.
-
What is the central argument of The Single Best Investment?
That owning high-quality companies with a long history of growing dividends is the most reliable way for individual investors to build wealth over time — superior to chasing capital appreciation, bond investing, or high-yield stocks.
-
Who should read this book?
Investors who want an income component to their portfolio, people nearing or in retirement who care about cash flow, and anyone skeptical of pure capital appreciation strategies who wants a framework for thinking about dividends as a return driver.
-
How does this strategy differ from just buying a dividend ETF?
Miller's framework selects for dividend growth — consistent annual increases — not just current yield. Many dividend ETFs mix both categories. His criteria, applied to individual stocks, would screen out high-yield names with stagnant or shrinking dividends that appear in many dividend-focused funds.
