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

— 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 ten year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Walmart Inc (NYSE: WMT) back in 2015. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 01/16/2015
$10,000

01/16/2015
  $38,590

01/15/2025
End date: 01/15/2025
Start price/share: $28.92
End price/share: $91.34
Starting shares: 345.78
Ending shares: 422.32
Dividends reinvested/share: $7.19
Total return: 285.75%
Average annual return: 14.45%
Starting investment: $10,000.00
Ending investment: $38,590.39

As we can see, the ten year investment result worked out quite well, with an annualized rate of return of 14.45%. This would have turned a $10K investment made 10 years ago into $38,590.39 today (as of 01/15/2025). On a total return basis, that’s a result of 285.75% (something to think about: how might WMT shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Walmart Inc paid investors a total of $7.19/share in dividends over the 10 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 .83/share, we calculate that WMT has a current yield of approximately 0.91%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .83 against the original $28.92/share purchase price. This works out to a yield on cost of 3.15%.
