“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Extra Space Storage Inc (NYSE: EXR)? Today, we examine the outcome of a five year investment into the stock back in 2015.

Start date: 11/12/2015


End date: 11/11/2020
Start price/share: $79.08
End price/share: $117.99
Starting shares: 126.45
Ending shares: 151.27
Dividends reinvested/share: $16.26
Total return: 78.49%
Average annual return: 12.28%
Starting investment: $10,000.00
Ending investment: $17,850.48

As we can see, the five year investment result worked out quite well, with an annualized rate of return of 12.28%. This would have turned a $10K investment made 5 years ago into $17,850.48 today (as of 11/11/2020). On a total return basis, that’s a result of 78.49% (something to think about: how might EXR shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Extra Space Storage Inc paid investors a total of $16.26/share in dividends over the 5 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 3.6/share, we calculate that EXR has a current yield of approximately 3.05%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.6 against the original $79.08/share purchase price. This works out to a yield on cost of 3.86%.
