“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— 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 two-decade holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Blackrock Inc (NYSE: BLK) back in 2001: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full two-decade investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 04/19/2001


End date: 04/16/2021
Start price/share: $34.10
End price/share: $811.45
Starting shares: 293.26
Ending shares: 437.28
Dividends reinvested/share: $114.89
Total return: 3,448.31%
Average annual return: 19.53%
Starting investment: $10,000.00
Ending investment: $354,783.10

The above analysis shows the two-decade investment result worked out exceptionally well, with an annualized rate of return of 19.53%. This would have turned a $10K investment made 20 years ago into $354,783.10 today (as of 04/16/2021). On a total return basis, that’s a result of 3,448.31% (something to think about: how might BLK shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Always an important consideration with a dividend-paying company is: should we reinvest our dividends?Over the past 20 years, Blackrock Inc has paid $114.89/share in dividends. For the above analysis, we assume that the investor reinvests dividends into new shares of stock (for the above calculations, the reinvestment is performed using closing price on ex-div date for that dividend).

Based upon the most recent annualized dividend rate of 16.52/share, we calculate that BLK has a current yield of approximately 2.04%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 16.52 against the original $34.10/share purchase price. This works out to a yield on cost of 5.98%.
