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

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a ten year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Northrop Grumman Corp (NYSE: NOC) back in 2014. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 11/25/2014
$10,000

11/25/2014
  $41,128

11/22/2024
End date: 11/22/2024
Start price/share: $141.56
End price/share: $496.87
Starting shares: 70.64
Ending shares: 82.78
Dividends reinvested/share: $51.41
Total return: 311.29%
Average annual return: 15.19%
Starting investment: $10,000.00
Ending investment: $41,128.97

As shown above, the ten year investment result worked out exceptionally well, with an annualized rate of return of 15.19%. This would have turned a $10K investment made 10 years ago into $41,128.97 today (as of 11/22/2024). On a total return basis, that’s a result of 311.29% (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 $51.41/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 8.24/share, we calculate that NOC has a current yield of approximately 1.66%. 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 $141.56/share purchase price. This works out to a yield on cost of 1.17%.

Here’s one more great investment quote before you go:
“If a speculator is correct half of the time, he is hitting a good average. Even being right 3 or 4 times out of 10 should yield a person a fortune if he has the sense to cut his losses quickly on the ventures where he is wrong.” — Bernard Baruch
