“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
A long-term holding period can materially change the economics of equity investing, particularly when a company compounds through both share-price appreciation and reinvested dividends. That is the case with Wabtec Corp (NYSE: WAB), whose 20-year total return illustrates how patient ownership of an industrial business can turn a modest initial investment into a substantially larger sum.
Using the period from 06/08/2006 through 06/05/2026, a $10,000 investment in WAB stock grew to $171,360.32 with dividends reinvested. That equates to a total return of 1,614.86% and an average annual return of 15.26%. The result underscores a central point about long-duration equity returns: over extended periods, compounding often matters more than any single year’s market move.

The basic math is straightforward. A starting share price of $16.39 meant a $10,000 investment purchased approximately 610.13 shares. With dividends reinvested over time, the position grew to 658.55 shares by the end of the measurement period. At an ending share price of $260.40, the value of the investment reached $171,360.32.

What Drove Wabtec’s Long-Term Return?
Most of the gain came from capital appreciation rather than income. Wabtec’s share price rose from $16.39 to $260.40 over the period, a substantial increase on its own. Dividend reinvestment added incrementally by increasing the share count from 610.13 to 658.55. In other words, the dividend contribution was meaningful, but the dominant engine of return was the company’s long-run equity value creation as reflected in the stock price.
That distinction matters. For lower-yielding industrial companies, total return often depends less on current income and more on earnings growth, margin expansion, operational execution, and the market’s willingness to capitalize those improvements at a higher share price. Reinvested dividends can still enhance results, but they typically act as a secondary compounding lever rather than the primary source of return.
How Much Did Dividends Matter?
Over the 20-year period, Wabtec paid $7.24 per share in dividends that were assumed to be reinvested. That lifted the share count by roughly 48.42 shares beyond the original purchase amount. The calculation uses the closing price on each ex-dividend date for reinvestment purposes.
Based on the most recent annualized dividend rate of $1.24 per share, WAB has a current yield of approximately 0.48%. Another useful metric is yield on cost, which compares the current annualized dividend against the original purchase price rather than today’s share price. On that basis, a $1.24 annual dividend relative to a $16.39 starting price produces a yield on cost of about 7.57%.

Why Long Holding Periods Can Change Outcomes
A result like this highlights the practical difference between trading around shorter-term price moves and allowing a business to compound over many years. Multi-decade returns are rarely linear. They usually include recessions, sector rotations, valuation resets, and periods when a stock appears to go nowhere. Yet when a company ultimately delivers sustained growth in cash generation and market value, time can convert ordinary annual gains into exceptional cumulative results.
That is why annualized return is often more informative than headline total return alone. A 15.26% annualized return sustained over two decades is not simply a good year repeated several times; it is the mathematical foundation for the large ending value. Compounding at that rate over long periods is what transformed a five-figure investment into a six-figure one.
“As time goes on, I get more and more convinced that the right method of investment is to put fairly large sums into enterprises which one thinks one knows something about and in the management of which one thoroughly believes.” — John Maynard Keynes
