“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”
— Warren Buffett
The Warren Buffett investment philosophy calls for a long-term investment horizon, where a decade-long holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Iron Mountain Inc (NYSE: IRM)? Today, we examine the outcome of a decade-long investment into the stock back in 2011.
| Start date: | 07/07/2011 |

| End date: | 07/06/2021 | ||||

| Starting shares: | 305.62 | ||||

| Dividends reinvested/share: | $23.23 | ||||

| Average annual return: | 10.18% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $26,379.00 | ||||
As we can see, the decade-long investment result worked out quite well, with an annualized rate of return of 10.18%. This would have turned a $10K investment made 10 years ago into $26,379.00 today (as of 07/06/2021). On a total return basis, that’s a result of 163.74% (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.]
Dividends are always an important investment factor to consider, and Iron Mountain Inc has paid $23.23/share in dividends to shareholders over the past 10 years we looked at above. Many an investor will only invest in stocks that pay dividends, so this component of total return is always an important consideration. Automated reinvestment of dividends into additional shares of stock can be a great way for an investor to compound their returns. The above calculations are done with the assuption that dividends received over time are reinvested (the calcuations use the 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 5.83%. 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 $32.72/share purchase price. This works out to a yield on cost of 17.82%.

“The most important quality for an investor is temperament, not intellect. You need a temperament that neither derives great pleasure from being with the crowd or against the crowd.” — Warren Buffett
