“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
A long holding period can materially reshape investment outcomes, particularly when capital appreciation and dividend reinvestment work together over time. In the case of Wabtec Corp (NYSE: WAB), a $10,000 investment made in 2006 and held through September 2026 would have grown into a substantially larger sum, illustrating the compounding power of long-term total return.

The numbers are straightforward: a $10,000 investment in Wabtec on 09/18/2006 would have grown to $212,631.54 by 09/15/2026, assuming dividends were reinvested. That equates to a 2,025.92% total return and an annualized return of 16.51%. [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
What Drove Wabtec’s Long-Term Return?
Most of the gain came from share price appreciation. Wabtec’s stock price rose from $14.13 to $278.12 over the measurement period, a substantial increase that reflects the importance of business growth and valuation expansion in long-duration equity returns.
Dividends contributed as well, though to a lesser extent. Over the 20-year period, the investment accumulated $7.55 per share in reinvested dividends, increasing the share count from 707.71 to 764.39. That incremental share growth matters because each additional share participates in future dividend payments and price appreciation.
This illustrates a basic but important distinction in equity analysis:
- Price return measures the change in the stock price alone.
- Total return includes both price appreciation and dividends, assuming cash distributions are retained or reinvested.
- Reinvestment can modestly or materially improve long-term results, depending on yield, valuation, and time horizon.
How Dividend Reinvestment Changed the Outcome
For this calculation, dividends are assumed to have been reinvested on each ex-dividend date using the closing price. That assumption is important because it produces a more complete picture of shareholder return than price alone. Even with a relatively modest yield, reinvestment added to the ending share count and compounded over time.
Wabtec is not a high-yield equity. Based on the most recent annualized dividend rate of $1.24 per share, the current yield is approximately 0.45%. Even so, long-term holders may look beyond current yield and consider yield on cost, which compares the current annual dividend to the original purchase price. Using the 2006 purchase price of $14.13, Wabtec’s current annualized dividend implies a yield on cost of about 8.78%.
Why the Starting Valuation Matters
Strong long-term outcomes are rarely explained by a single factor. Time in the market matters, but so do the starting price, the company’s operating performance, capital allocation, and the durability of its end markets. In Wabtec’s case, a low initial share price relative to the ending value did much of the heavy lifting, while dividend reinvestment provided an additional layer of compounding.
That also helps explain why retrospective return figures should be read carefully. A 20-year annualized return of 16.51% is an excellent realized outcome, but it does not mean future returns will follow the same path. Long-term return potential depends on future earnings growth, cash generation, reinvestment opportunities, and the valuation investors are willing to assign to those fundamentals.
Key Takeaway
A $10,000 investment in Wabtec stock in 2006 grew to more than $212,000 by September 2026, with the result driven primarily by price appreciation and supported by reinvested dividends. The exercise underscores a broader point: over long holding periods, even modest dividend contributions can meaningfully enhance total return when paired with sustained stock price gains.
