“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 ten year 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 SL Green Realty Corp (NYSE: SLG) back in 2010, holding through to today.

Start date: 04/13/2010
$10,000

04/13/2010
$10,937

04/09/2020
End date: 04/09/2020
Start price/share: $62.05
End price/share: $54.17
Starting shares: 161.16
Ending shares: 201.90
Dividends reinvested/share: $21.13
Total return: 9.37%
Average annual return: 0.90%
Starting investment: $10,000.00
Ending investment: $10,937.07

As shown above, the ten year investment result worked out as follows, with an annualized rate of return of 0.90%. This would have turned a $10K investment made 10 years ago into $10,937.07 today (as of 04/09/2020). On a total return basis, that’s a result of 9.37% (something to think about: how might SLG shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Beyond share price change, another component of SLG’s total return these past 10 years has been the payment by SL Green Realty Corp of $21.13/share in dividends to shareholders. Automatic reinvestment of dividends can be a wonderful way to compound returns, and for the above calculations we presume that dividends are reinvested into additional shares of stock. (For the purpose of these calcuations, the closing price on ex-date is used).

Based upon the most recent annualized dividend rate of 3.54/share, we calculate that SLG has a current yield of approximately 6.54%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.54 against the original $62.05/share purchase price. This works out to a yield on cost of 10.54%.

Another great investment quote to think about:
“October is one of the peculiarly dangerous months to speculate in stocks. The others are July, January, September, April, November, May, March, June, December, August and February.” — Mark Twain
