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

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a two-decade holding period for an investor who was considering Costco Wholesale Corp (NASD: COST) back in 2002, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 10/07/2002
$10,000

10/07/2002
  $237,059

10/06/2022
End date: 10/06/2022
Start price/share: $29.18
End price/share: $482.49
Starting shares: 342.70
Ending shares: 491.48
Dividends reinvested/share: $55.90
Total return: 2,271.36%
Average annual return: 17.14%
Starting investment: $10,000.00
Ending investment: $237,059.48

The above analysis shows the two-decade investment result worked out exceptionally well, with an annualized rate of return of 17.14%. This would have turned a $10K investment made 20 years ago into $237,059.48 today (as of 10/06/2022). On a total return basis, that’s a result of 2,271.36% (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.]

Many investors out there refuse to own any stock that lacks a dividend; in the case of Costco Wholesale Corp, investors have received $55.90/share in dividends these past 20 years examined in the exercise above. This means total return was driven not just by share price, but also by the dividends received (and what the investor did with those dividends). For this exercise, what we’ve done with the dividends is to assume they are reinvestted — i.e. used to purchase additional shares (the calculations use closing price on ex-date).

Based upon the most recent annualized dividend rate of 3.6/share, we calculate that COST has a current yield of approximately 0.75%. 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 $29.18/share purchase price. This works out to a yield on cost of 2.57%.

Another great investment quote to think about:
“If you’re looking for a home run, a great investment for five years or 10 years or more, then the only way to beat this enormous fog that covers the future is to identify a long-term trend that will give a particular business some sort of edge.” — Ralph Wanger
