“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— 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 two-decade holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Iron Mountain Inc (NYSE: IRM) back in 2003: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full two-decade investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 04/28/2003
$10,000

04/28/2003
  $75,048

04/25/2023
End date: 04/25/2023
Start price/share: $16.50
End price/share: $54.26
Starting shares: 606.06
Ending shares: 1,383.66
Dividends reinvested/share: $28.32
Total return: 650.77%
Average annual return: 10.60%
Starting investment: $10,000.00
Ending investment: $75,048.55

As we can see, the two-decade investment result worked out quite well, with an annualized rate of return of 10.60%. This would have turned a $10K investment made 20 years ago into $75,048.55 today (as of 04/25/2023). On a total return basis, that’s a result of 650.77% (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.]

Always an important consideration with a dividend-paying company is: should we reinvest our dividends?Over the past 20 years, Iron Mountain Inc has paid $28.32/share in dividends. For the above analysis, we assume that the investor reinvests dividends into new shares of stock (for the above calculations, the reinvestment is performed using closing price on ex-div date for that dividend).

Based upon the most recent annualized dividend rate of 2.474/share, we calculate that IRM has a current yield of approximately 4.56%. 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 $16.50/share purchase price. This works out to a yield on cost of 27.64%.

One more piece of investment wisdom to leave you with:
“If a speculator is correct half of the time, he is hitting a good average. Even being right 3 or 4 times out of 10 should yield a person a fortune if he has the sense to cut his losses quickly on the ventures where he is wrong.” — Bernard Baruch
