“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a twenty year holding period possibly?
Suppose a “buy-and-hold” investor was considering an investment into Iron Mountain Inc (NYSE: IRM) back in 2000: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full twenty year investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.
| Start date: | 11/06/2000 |
|
|||
| End date: | 11/03/2020 | ||||
| Start price/share: | $8.92 | ||||
| End price/share: | $27.30 | ||||
| Starting shares: | 1,121.08 | ||||
| Ending shares: | 2,230.99 | ||||
| Dividends reinvested/share: | $22.13 | ||||
| Total return: | 509.06% | ||||
| Average annual return: | 9.45% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $60,887.79 | ||||
As shown above, the twenty year investment result worked out well, with an annualized rate of return of 9.45%. This would have turned a $10K investment made 20 years ago into $60,887.79 today (as of 11/03/2020). On a total return basis, that’s a result of 509.06% (something to think about: how might IRM shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Iron Mountain Inc paid investors a total of $22.13/share in dividends over the 20 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 2.474/share, we calculate that IRM has a current yield of approximately 9.06%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.474 against the original $8.92/share purchase price. This works out to a yield on cost of 101.57%.
