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

— 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 decade-long period?

Today, let’s look backwards in time to 2010, and take a look at what happened to investors who asked that very question about Seagate Technology plc (NASD: STX), by taking a look at the investment outcome over a decade-long holding period.

Start date: 05/12/2010
$10,000

05/12/2010
$41,125

05/11/2020
End date: 05/11/2020
Start price/share: $18.99
End price/share: $49.86
Starting shares: 526.59
Ending shares: 824.85
Dividends reinvested/share: $17.65
Total return: 311.27%
Average annual return: 15.18%
Starting investment: $10,000.00
Ending investment: $41,125.11

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 15.18%. This would have turned a $10K investment made 10 years ago into $41,125.11 today (as of 05/11/2020). On a total return basis, that’s a result of 311.27% (something to think about: how might STX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Dividends are always an important investment factor to consider, and Seagate Technology plc has paid $17.65/share in dividends to shareholders over the past 10 years we looked at above. Many an investor will only invest in stocks that pay dividends, so this component of total return is always an important consideration. Automated reinvestment of dividends into additional shares of stock can be a great way for an investor to compound their returns. The above calculations are done with the assuption that dividends received over time are reinvested (the calcuations use the closing price on ex-date).

Based upon the most recent annualized dividend rate of 2.6/share, we calculate that STX has a current yield of approximately 5.21%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.6 against the original $18.99/share purchase price. This works out to a yield on cost of 27.44%.

One more piece of investment wisdom to leave you with:
“The most important quality for an investor is temperament, not intellect. You need a temperament that neither derives great pleasure from being with the crowd or against the crowd.” — Warren Buffett
