“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”
— 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 decade-long holding period possibly?
Suppose a “buy-and-hold” investor was considering an investment into Iron Mountain Inc (NYSE: IRM) back in 2011: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full decade-long investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.
| Start date: | 11/29/2011 |
|
|||
| End date: | 11/26/2021 | ||||
| Start price/share: | $27.38 | ||||
| End price/share: | $46.69 | ||||
| Starting shares: | 365.23 | ||||
| Ending shares: | 747.30 | ||||
| Dividends reinvested/share: | $23.62 | ||||
| Total return: | 248.92% | ||||
| Average annual return: | 13.31% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $34,888.51 | ||||
As we can see, the decade-long investment result worked out quite well, with an annualized rate of return of 13.31%. This would have turned a $10K investment made 10 years ago into $34,888.51 today (as of 11/26/2021). On a total return basis, that’s a result of 248.92% (something to think about: how might IRM shares perform over the next 10 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 Iron Mountain Inc, investors have received $23.62/share in dividends these past 10 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 2.474/share, we calculate that IRM has a current yield of approximately 5.30%. 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 $27.38/share purchase price. This works out to a yield on cost of 19.36%.
