“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— 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 two-decade holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Iron Mountain Inc (NYSE: IRM) back in 1999. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:
| Start date: | 04/09/1999 |
|
|||
| End date: | 04/08/2019 | ||||
| Start price/share: | $8.32 | ||||
| End price/share: | $36.30 | ||||
| Starting shares: | 1,201.92 | ||||
| Ending shares: | 2,118.52 | ||||
| Dividends reinvested/share: | $18.43 | ||||
| Total return: | 669.02% | ||||
| Average annual return: | 10.73% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $76,876.06 | ||||
As shown above, the two-decade investment result worked out quite well, with an annualized rate of return of 10.73%. This would have turned a $10K investment made 20 years ago into $76,876.06 today (as of 04/08/2019). On a total return basis, that’s a result of 669.02% (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.]
Dividends are always an important investment factor to consider, and Iron Mountain Inc has paid $18.43/share in dividends to shareholders over the past 20 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 2.444/share, we calculate that IRM has a current yield of approximately 6.73%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.444 against the original $8.32/share purchase price. This works out to a yield on cost of 80.89%.
