“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 Western Digital Corp (NASD: WDC)? Today, we examine the outcome of a decade-long investment into the stock back in 2012.

Start date: 11/16/2012
$10,000

11/16/2012
  $14,093

11/15/2022
End date: 11/15/2022
Start price/share: $34.58
End price/share: $39.46
Starting shares: 289.18
Ending shares: 357.16
Dividends reinvested/share: $13.30
Total return: 40.93%
Average annual return: 3.49%
Starting investment: $10,000.00
Ending investment: $14,093.69

The above analysis shows the decade-long investment result worked out as follows, with an annualized rate of return of 3.49%. This would have turned a $10K investment made 10 years ago into $14,093.69 today (as of 11/15/2022). On a total return basis, that’s a result of 40.93% (something to think about: how might WDC shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Western Digital Corp paid investors a total of $13.30/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 WDC has a current yield of approximately 5.07%. 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 $34.58/share purchase price. This works out to a yield on cost of 14.66%.
