“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Micron Technology Inc. (NASD: MU) back in 2020. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:
| Start date: | 05/26/2020 |
|
|||
| End date: | 05/23/2025 | ||||
| Start price/share: | $45.80 | ||||
| End price/share: | $93.37 | ||||
| Starting shares: | 218.34 | ||||
| Ending shares: | 223.37 | ||||
| Dividends reinvested/share: | $1.68 | ||||
| Total return: | 108.56% | ||||
| Average annual return: | 15.86% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $20,860.14 | ||||
As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 15.86%. This would have turned a $10K investment made 5 years ago into $20,860.14 today (as of 05/23/2025). On a total return basis, that’s a result of 108.56% (something to think about: how might MU shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Micron Technology Inc. paid investors a total of $1.68/share in dividends over the 5 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 .46/share, we calculate that MU has a current yield of approximately 0.49%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .46 against the original $45.80/share purchase price. This works out to a yield on cost of 1.07%.
