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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a decade-long holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Northrop Grumman Corp (NYSE: NOC)? Today, we examine the outcome of a decade-long investment into the stock back in 2009.

Start date: 09/23/2009
$10,000

09/23/2009
$99,678

09/20/2019
End date: 09/20/2019
Start price/share: $46.58
End price/share: $368.18
Starting shares: 214.68
Ending shares: 270.79
Dividends reinvested/share: $30.26
Total return: 896.98%
Average annual return: 25.86%
Starting investment: $10,000.00
Ending investment: $99,678.99

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 25.86%. This would have turned a $10K investment made 10 years ago into $99,678.99 today (as of 09/20/2019). On a total return basis, that’s a result of 896.98% (something to think about: how might NOC shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Northrop Grumman Corp paid investors a total of $30.26/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 5.28/share, we calculate that NOC has a current yield of approximately 1.43%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 5.28 against the original $46.58/share purchase price. This works out to a yield on cost of 3.07%.
