“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 two-decade period?

Today, let’s look backwards in time to 2004, and take a look at what happened to investors who asked that very question about Northrop Grumman Corp (NYSE: NOC), by taking a look at the investment outcome over a two-decade holding period.

Start date: 10/01/2004
$10,000

10/01/2004
  $165,924

09/30/2024
End date: 09/30/2024
Start price/share: $48.52
End price/share: $528.07
Starting shares: 206.10
Ending shares: 314.33
Dividends reinvested/share: $67.99
Total return: 1,559.90%
Average annual return: 15.07%
Starting investment: $10,000.00
Ending investment: $165,924.43

As shown above, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 15.07%. This would have turned a $10K investment made 20 years ago into $165,924.43 today (as of 09/30/2024). On a total return basis, that’s a result of 1,559.90% (something to think about: how might NOC shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Northrop Grumman Corp paid investors a total of $67.99/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 8.24/share, we calculate that NOC has a current yield of approximately 1.56%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 8.24 against the original $48.52/share purchase price. This works out to a yield on cost of 3.22%.
