“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— 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 twenty year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Costco Wholesale Corp (NASD: COST) back in 1999: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full twenty year investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 08/02/1999
$10,000

08/02/1999
$102,042

07/31/2019
End date: 07/31/2019
Start price/share: $36.84
End price/share: $275.63
Starting shares: 271.44
Ending shares: 370.07
Dividends reinvested/share: $36.19
Total return: 920.01%
Average annual return: 12.31%
Starting investment: $10,000.00
Ending investment: $102,042.94

The above analysis shows the twenty year investment result worked out quite well, with an annualized rate of return of 12.31%. This would have turned a $10K investment made 20 years ago into $102,042.94 today (as of 07/31/2019). On a total return basis, that’s a result of 920.01% (something to think about: how might COST shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Costco Wholesale Corp paid investors a total of $36.19/share in dividends over the 20 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).

Based upon the most recent annualized dividend rate of 2.6/share, we calculate that COST has a current yield of approximately 0.94%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.6 against the original $36.84/share purchase price. This works out to a yield on cost of 2.55%.

One more piece of investment wisdom to leave you with:
