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

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a twenty year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Costco Wholesale Corp (NASD: COST) back in 2003. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 01/31/2003


End date: 01/30/2023
Start price/share: $28.87
End price/share: $503.28
Starting shares: 346.38
Ending shares: 497.66
Dividends reinvested/share: $56.80
Total return: 2,404.64%
Average annual return: 17.46%
Starting investment: $10,000.00
Ending investment: $250,360.52

The above analysis shows the twenty year investment result worked out exceptionally well, with an annualized rate of return of 17.46%. This would have turned a $10K investment made 20 years ago into $250,360.52 today (as of 01/30/2023). On a total return basis, that’s a result of 2,404.64% (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.]

Always an important consideration with a dividend-paying company is: should we reinvest our dividends?Over the past 20 years, Costco Wholesale Corp has paid $56.80/share in dividends. For the above analysis, we assume that the investor reinvests dividends into new shares of stock (for the above calculations, the reinvestment is performed using closing price on ex-div date for that dividend).

Based upon the most recent annualized dividend rate of 3.6/share, we calculate that COST has a current yield of approximately 0.72%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.6 against the original $28.87/share purchase price. This works out to a yield on cost of 2.49%.
