“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
A long-term investment in Waters Corp. (NYSE: WAT) illustrates how sustained business execution can translate into strong shareholder returns over time. Using a buy-and-hold framework, a $10,000 investment made on 08/24/2006 would have grown to $98,437.16 by 08/21/2026, producing an annualized return of 12.11% and a total return of 883.95%.
The result is especially notable because Waters is not a high-yield dividend story. In this case, value creation came almost entirely from stock price appreciation rather than income reinvestment, underscoring a key distinction in equity returns: some companies compound through cash distributions, while others do so through earnings growth, margin strength, and persistent market leadership.

What Drove the 20-Year Return?
The math here is straightforward: the share price rose from $41.74 to $410.70 over the holding period, while the share count remained unchanged at 239.58 because Waters did not contribute return through dividend reinvestment in this calculation. That makes WAT a useful example of pure capital appreciation over a long duration.
Waters Corporation is known for analytical instruments and related software and services, with a significant presence in areas such as liquid chromatography, mass spectrometry, and laboratory workflows used across pharmaceuticals, life sciences, industrial applications, and academic research. Businesses with specialized instrumentation, recurring service relationships, and entrenched customer workflows can sometimes generate durable economics over time, particularly when their installed base supports follow-on revenue beyond the initial equipment sale.
Over a 20-year span, a return profile like this typically reflects more than short-term multiple expansion. It usually requires a combination of factors such as steady revenue growth, resilient margins, disciplined capital allocation, and a market position strong enough to maintain pricing power and customer retention through multiple economic cycles.
Key Takeaways From the WAT Buy-and-Hold Outcome
- Annualized returns matter more than headline gains. An 883.95% total return is substantial, but the 12.11% annualized return is the more useful measure for comparing long-term investments.
- Compounding works over long periods. The increase from $10,000 to $98,437.16 shows how sustained double-digit annual returns can produce large absolute gains over two decades.
- Not all strong compounders are dividend payers. In WAT’s case, return came from appreciation rather than reinvested payouts.
- Business quality often reveals itself over time. Long holding periods tend to reward companies that can defend their competitive position and reinvest effectively.
Why Annualized Return Is the Critical Metric
For long-horizon performance analysis, annualized return is often the most informative figure because it converts a multi-year outcome into a standardized yearly rate. That allows investors to compare one stock’s long-term compounding profile against alternatives such as broad equity benchmarks, other individual companies, or different portfolio strategies.
Here, a 12.11% annualized return over roughly two decades transformed a five-figure investment into nearly six figures. That is the practical significance of compounding: the later years of a successful holding period often contribute disproportionately to the final result.
As shown above, the two-decade investment result was strong by any conventional long-term measure. This would have turned a $10,000 investment made 20 years earlier into $98,437.16 as of 08/21/2026. On a total return basis, that amounts to 883.95%. [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
One implication of this historical outcome is that long-term winners do not always look dramatic in any single year. In many cases, the strongest results emerge from extended periods of consistent execution, with compounding doing most of the work.
Here’s one more investment observation worth keeping in mind:
