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

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a ten year holding period for an investor who was considering SL Green Realty Corp (NYSE: SLG) back in 2009, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 05/22/2009
$10,000

05/22/2009
$50,227

05/21/2019
End date: 05/21/2019
Start price/share: $21.19
End price/share: $87.23
Starting shares: 471.92
Ending shares: 575.78
Dividends reinvested/share: $18.65
Total return: 402.25%
Average annual return: 17.51%
Starting investment: $10,000.00
Ending investment: $50,227.35

As we can see, the ten year investment result worked out exceptionally well, with an annualized rate of return of 17.51%. This would have turned a $10K investment made 10 years ago into $50,227.35 today (as of 05/21/2019). On a total return basis, that’s a result of 402.25% (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.]

Notice that SL Green Realty Corp paid investors a total of $18.65/share in dividends over the 10 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 ex-date is used for the reinvestment of a given dividend).

Based upon the most recent annualized dividend rate of 3.4/share, we calculate that SLG has a current yield of approximately 3.90%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.4 against the original $21.19/share purchase price. This works out to a yield on cost of 18.40%.
