“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a twenty year period?

Today, let’s look backwards in time to 1999, and take a look at what happened to investors who asked that very question about Sempra Energy (NYSE: SRE), by taking a look at the investment outcome over a twenty year holding period.

Start date: 12/09/1999
$10,000

12/09/1999
$160,964

12/06/2019
End date: 12/06/2019
Start price/share: $18.25
End price/share: $145.84
Starting shares: 547.95
Ending shares: 1,102.86
Dividends reinvested/share: $41.03
Total return: 1,508.41%
Average annual return: 14.90%
Starting investment: $10,000.00
Ending investment: $160,964.87

As shown above, the twenty year investment result worked out quite well, with an annualized rate of return of 14.90%. This would have turned a $10K investment made 20 years ago into $160,964.87 today (as of 12/06/2019). On a total return basis, that’s a result of 1,508.41% (something to think about: how might SRE shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Sempra Energy paid investors a total of $41.03/share in dividends over the 20 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 3.87/share, we calculate that SRE has a current yield of approximately 2.65%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.87 against the original $18.25/share purchase price. This works out to a yield on cost of 14.52%.

Another great investment quote to think about:
“Be fearful when others are greedy; be greedy when others are fearful.” — Warren Buffett
