“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a five year holding period for an investor who was considering PerkinElmer, Inc. (NYSE: PKI) back in 2016, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 03/28/2016
$10,000

03/28/2016
$26,536

03/25/2021
End date: 03/25/2021
Start price/share: $48.30
End price/share: $125.85
Starting shares: 207.04
Ending shares: 210.88
Dividends reinvested/share: $1.40
Total return: 165.39%
Average annual return: 21.58%
Starting investment: $10,000.00
Ending investment: $26,536.63

The above analysis shows the five year investment result worked out exceptionally well, with an annualized rate of return of 21.58%. This would have turned a $10K investment made 5 years ago into $26,536.63 today (as of 03/25/2021). On a total return basis, that’s a result of 165.39% (something to think about: how might PKI shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that PerkinElmer, Inc. paid investors a total of $1.40/share in dividends over the 5 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 .28/share, we calculate that PKI has a current yield of approximately 0.22%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .28 against the original $48.30/share purchase price. This works out to a yield on cost of 0.46%.

Another great investment quote to think about:
