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

— Warren Buffett

A critical pearl of wisdom from Warren Buffett teaches us that with any potential stock investment we may make, as soon as our buy order is filled we will have a choice: to remain a co-owner of that company for the long haul, or to react to the inevitable short-term ups and downs that the stock market is famous for (sometimes sharp ups and downs).

The reality of this choice forces us to challenge our confidence in any given company we might invest into, and keep our eyes on the long-term time horizon. The market may go up and down the interim, but over a two-decade holding period, will the investment succeed?

Back in 2000, investors may have been asking themselves that very question about Boston Properties Inc (NYSE: BXP). Let’s examine what would have happened over a two-decade holding period, had you invested in BXP shares back in 2000 and held on.

Start date: 12/18/2000
$10,000

12/18/2000
$55,558

12/15/2020
End date: 12/15/2020
Start price/share: $44.38
End price/share: $101.00
Starting shares: 225.35
Ending shares: 550.02
Dividends reinvested/share: $75.37
Total return: 455.52%
Average annual return: 8.95%
Starting investment: $10,000.00
Ending investment: $55,558.27

As we can see, the two-decade investment result worked out well, with an annualized rate of return of 8.95%. This would have turned a $10K investment made 20 years ago into $55,558.27 today (as of 12/15/2020). On a total return basis, that’s a result of 455.52% (something to think about: how might BXP shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Boston Properties Inc paid investors a total of $75.37/share in dividends over the 20 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 3.89%. 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 $44.38/share purchase price. This works out to a yield on cost of 8.77%.

Another great investment quote to think about:
“There’s a virtuous cycle when people have to defend challenges to their ideas. Any gaps in thinking or analysis become clear pretty quickly when smart people ask good, logical questions.” — Joel Greenblatt
