“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a ten year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Waters Corp. (NYSE: WAT) back in 2009: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full ten year investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 04/30/2009
$10,000

04/30/2009
$48,006

04/29/2019
End date: 04/29/2019
Start price/share: $44.17
End price/share: $212.12
Starting shares: 226.40
Ending shares: 226.40
Dividends reinvested/share: $0.00
Total return: 380.24%
Average annual return: 16.98%
Starting investment: $10,000.00
Ending investment: $48,006.80

As shown above, the ten year investment result worked out exceptionally well, with an annualized rate of return of 16.98%. This would have turned a $10K investment made 10 years ago into $48,006.80 today (as of 04/29/2019). On a total return basis, that’s a result of 380.24% (something to think about: how might WAT shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
