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

— Warren Buffett

This inspiring quote from Warren Buffett teaches us the importance of considering our investment time horizon when approaching any given investment: Could we envision ourselves holding the stock we are considering for many years? Even a decade-long holding period potentially?

For “buy-and-hold” investors taking a long-term view, what’s important isn’t the short-term stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 10 years to 2012, investors considering an investment into shares of Juniper Networks Inc (NYSE: JNPR) may have been pondering this very question and thinking about their potential investment result over a full decade-long time horizon. Here’s how that would have worked out.

Start date: 12/10/2012


End date: 12/07/2022
Start price/share: $19.28
End price/share: $31.97
Starting shares: 518.67
Ending shares: 634.77
Dividends reinvested/share: $5.32
Total return: 102.94%
Average annual return: 7.34%
Starting investment: $10,000.00
Ending investment: $20,301.66

The above analysis shows the decade-long investment result worked out well, with an annualized rate of return of 7.34%. This would have turned a $10K investment made 10 years ago into $20,301.66 today (as of 12/07/2022). On a total return basis, that’s a result of 102.94% (something to think about: how might JNPR shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Many investors out there refuse to own any stock that lacks a dividend; in the case of Juniper Networks Inc, investors have received $5.32/share in dividends these past 10 years examined in the exercise above. This means total return was driven not just by share price, but also by the dividends received (and what the investor did with those dividends). For this exercise, what we’ve done with the dividends is to assume they are reinvestted — i.e. used to purchase additional shares (the calculations use closing price on ex-date).

Based upon the most recent annualized dividend rate of .84/share, we calculate that JNPR has a current yield of approximately 2.63%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .84 against the original $19.28/share purchase price. This works out to a yield on cost of 13.64%.

Another great investment quote to think about:
“Value investing requires a great deal of hard work, unusually strict discipline, and a long-term investment horizon. Few are willing and able to devote sufficient time and effort to become value investors, and only a fraction of those have the proper mind-set to succeed.” — Seth Klarman
