“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year period?

Today, let’s look backwards in time to 2020, and take a look at what happened to investors who asked that very question about Thermo Fisher Scientific Inc (NYSE: TMO), by taking a look at the investment outcome over a five year holding period.

Start date: 03/05/2020
$10,000

03/05/2020
  $16,706

03/04/2025
End date: 03/04/2025
Start price/share: $312.89
End price/share: $516.57
Starting shares: 31.96
Ending shares: 32.34
Dividends reinvested/share: $6.08
Total return: 67.08%
Average annual return: 10.81%
Starting investment: $10,000.00
Ending investment: $16,706.86

As shown above, the five year investment result worked out quite well, with an annualized rate of return of 10.81%. This would have turned a $10K investment made 5 years ago into $16,706.86 today (as of 03/04/2025). On a total return basis, that’s a result of 67.08% (something to think about: how might TMO shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Thermo Fisher Scientific Inc paid investors a total of $6.08/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 1.72/share, we calculate that TMO has a current yield of approximately 0.33%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.72 against the original $312.89/share purchase price. This works out to a yield on cost of 0.11%.
