“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 Boston Properties Inc (NYSE: BXP)? Today, we examine the outcome of a five year investment into the stock back in 2017.

Start date: 04/26/2017


End date: 04/25/2022
Start price/share: $127.35
End price/share: $125.82
Starting shares: 78.52
Ending shares: 92.42
Dividends reinvested/share: $18.45
Total return: 16.28%
Average annual return: 3.06%
Starting investment: $10,000.00
Ending investment: $11,626.55

As shown above, the five year investment result worked out as follows, with an annualized rate of return of 3.06%. This would have turned a $10K investment made 5 years ago into $11,626.55 today (as of 04/25/2022). On a total return basis, that’s a result of 16.28% (something to think about: how might BXP shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Boston Properties Inc paid investors a total of $18.45/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 3.92/share, we calculate that BXP has a current yield of approximately 3.12%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.92 against the original $127.35/share purchase price. This works out to a yield on cost of 2.45%.
