“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 twodecade holding period possibly?
Suppose a “buyandhold” investor was considering an investment into Becton, Dickinson & Co (NYSE: BDX) back in 2001: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full twodecade investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.
Start date:  08/13/2001 


End date:  08/11/2021  
Start price/share:  $35.35  
End price/share:  $240.66  
Starting shares:  282.89  
Ending shares:  387.61  
Dividends reinvested/share:  $35.28  
Total return:  832.83%  
Average annual return:  11.81%  
Starting investment:  $10,000.00  
Ending investment:  $93,327.88 
The above analysis shows the twodecade investment result worked out quite well, with an annualized rate of return of 11.81%. This would have turned a $10K investment made 20 years ago into $93,327.88 today (as of 08/11/2021). On a total return basis, that’s a result of 832.83% (something to think about: how might BDX shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Becton, Dickinson & Co paid investors a total of $35.28/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 exdate is used for the reinvestment of a given dividend).
Based upon the most recent annualized dividend rate of 3.32/share, we calculate that BDX has a current yield of approximately 1.38%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.32 against the original $35.35/share purchase price. This works out to a yield on cost of 3.90%.
