“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a decade-long holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Blackrock Inc (NYSE: BLK) back in 2010, holding through to today.

Start date: 02/22/2010
$10,000

02/22/2010
$33,975

02/20/2020
End date: 02/20/2020
Start price/share: $217.23
End price/share: $566.92
Starting shares: 46.03
Ending shares: 59.93
Dividends reinvested/share: $83.04
Total return: 239.77%
Average annual return: 13.01%
Starting investment: $10,000.00
Ending investment: $33,975.73

As we can see, the decade-long investment result worked out quite well, with an annualized rate of return of 13.01%. This would have turned a $10K investment made 10 years ago into $33,975.73 today (as of 02/20/2020). On a total return basis, that’s a result of 239.77% (something to think about: how might BLK shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Many investors out there refuse to own any stock that lacks a dividend; in the case of Blackrock Inc, investors have received $83.04/share in dividends these past 10 years examined in the exercise above. This means total return was driven not just by share price, but also by the dividends received (and what the investor did with those dividends). For this exercise, what we’ve done with the dividends is to assume they are reinvestted — i.e. used to purchase additional shares (the calculations use closing price on ex-date).

Based upon the most recent annualized dividend rate of 14.52/share, we calculate that BLK has a current yield of approximately 2.56%. 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 $217.23/share purchase price. This works out to a yield on cost of 1.18%.

Another great investment quote to think about:
“As time goes on, I get more and more convinced that the right method of investment is to put fairly large sums into enterprises which one thinks one knows something about and in the management of which one thoroughly believes.” — John Maynard Keynes
