“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”
— Warren Buffett
A critical pearl of wisdom from Warren Buffett teaches us that with any potential stock investment we may make, as soon as our buy order is filled we will have a choice: to remain a co-owner of that company for the long haul, or to react to the inevitable short-term ups and downs that the stock market is famous for (sometimes sharp ups and downs).
The reality of this choice forces us to challenge our confidence in any given company we might invest into, and keep our eyes on the long-term time horizon. The market may go up and down the interim, but over a decade-long holding period, will the investment succeed?
Back in 2015, investors may have been asking themselves that very question about Best Buy Inc (NYSE: BBY). Let’s examine what would have happened over a decade-long holding period, had you invested in BBY shares back in 2015 and held on.
| Start date: | 08/05/2015 |
|
|||
| End date: | 08/04/2025 | ||||
| Start price/share: | $32.00 | ||||
| End price/share: | $66.22 | ||||
| Starting shares: | 312.50 | ||||
| Ending shares: | 444.96 | ||||
| Dividends reinvested/share: | $25.05 | ||||
| Total return: | 194.65% | ||||
| Average annual return: | 11.41% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $29,478.06 | ||||
The above analysis shows the decade-long investment result worked out quite well, with an annualized rate of return of 11.41%. This would have turned a $10K investment made 10 years ago into $29,478.06 today (as of 08/04/2025). On a total return basis, that’s a result of 194.65% (something to think about: how might BBY shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Best Buy Inc paid investors a total of $25.05/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 3.8/share, we calculate that BBY has a current yield of approximately 5.74%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.8 against the original $32.00/share purchase price. This works out to a yield on cost of 17.94%.
Here’s one more great investment quote before you go:
“Thousands of experts study overbought indicators, head-and-shoulder patterns, put-call ratios, the Fed’s policy on money supply…and they can’t predict markets with any useful consistency, any more than the gizzard squeezers could tell the Roman emperors when the Huns would attack.” — Peter Lynch
