“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 ten 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 ten year investment into the stock back in 2013.

Start date: 10/30/2013
$10,000

10/30/2013
  $7,397

10/27/2023
End date: 10/27/2023
Start price/share: $105.06
End price/share: $52.42
Starting shares: 95.18
Ending shares: 141.09
Dividends reinvested/share: $41.63
Total return: -26.04%
Average annual return: -2.97%
Starting investment: $10,000.00
Ending investment: $7,397.69

The above analysis shows the ten year investment result worked out poorly, with an annualized rate of return of -2.97%. This would have turned a $10K investment made 10 years ago into $7,397.69 today (as of 10/27/2023). On a total return basis, that’s a result of -26.04% (something to think about: how might BXP shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Boston Properties Inc paid investors a total of $41.63/share in dividends over the 10 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 7.48%. 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 $105.06/share purchase price. This works out to a yield on cost of 7.12%.
