“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 Blackrock Inc (NYSE: BLK). Let’s examine what would have happened over a two-decade holding period, had you invested in BLK shares back in 2000 and held on.

Start date: 12/26/2000


End date: 12/22/2020
Start price/share: $39.31
End price/share: $693.52
Starting shares: 254.39
Ending shares: 377.05
Dividends reinvested/share: $110.76
Total return: 2,514.88%
Average annual return: 17.72%
Starting investment: $10,000.00
Ending investment: $261,335.96

As shown above, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 17.72%. This would have turned a $10K investment made 20 years ago into $261,335.96 today (as of 12/22/2020). On a total return basis, that’s a result of 2,514.88% (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 $110.76/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 14.52/share, we calculate that BLK has a current yield of approximately 2.09%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 14.52 against the original $39.31/share purchase price. This works out to a yield on cost of 5.32%.

Another great investment quote to think about:
“If you have more than 120 or 130 I.Q. points, you can afford to give the rest away. You don’t need extraordinary intelligence to succeed as an investor.” — Warren Buffett
