“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 National Oilwell Varco Inc (NYSE: NOV)? Today, we examine the outcome of a decade-long investment into the stock back in 2010.

Start date: 09/08/2010
$10,000

09/08/2010
$3,882

09/04/2020
End date: 09/04/2020
Start price/share: $35.94
End price/share: $12.15
Starting shares: 278.24
Ending shares: 319.41
Dividends reinvested/share: $6.57
Total return: -61.19%
Average annual return: -9.03%
Starting investment: $10,000.00
Ending investment: $3,882.35

As shown above, the decade-long investment result worked out poorly, with an annualized rate of return of -9.03%. This would have turned a $10K investment made 10 years ago into $3,882.35 today (as of 09/04/2020). On a total return basis, that’s a result of -61.19% (something to think about: how might NOV shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that National Oilwell Varco Inc paid investors a total of $6.57/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 .2/share, we calculate that NOV has a current yield of approximately 1.65%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .2 against the original $35.94/share purchase price. This works out to a yield on cost of 4.59%.

One more piece of investment wisdom to leave you with:
