“I buy on the assumption that they could close the market the next day and not reopen it for five years.”
— Warren Buffett
A key lesson we can learn from Warren Buffett, is about how to think about a potential stock investment in the context of a longterm time horizon. Every investor in a stock has a choice: bite our fingernails over the shortterm ups and downs that are inevitable with the stock market, or, zero in on stocks we are comfortable to simply buy and hold for the long haul — maybe even a five year holding period. Heck, investors can even choose to completely ignore the stock market’s shortrun quotations and instead go into their initial investment planning to hold on for years and years regardless of the fluctuations in price that might occur next.
Today, we examine what would have happened over a five year holding period, had you decided back in 2018 to buy shares of Targa Resources Corp (NYSE: TRGP) and simply hold through to today.
Start date:  10/03/2018 


End date:  10/02/2023  
Start price/share:  $58.38  
End price/share:  $83.43  
Starting shares:  171.29  
Ending shares:  209.29  
Dividends reinvested/share:  $8.91  
Total return:  74.61%  
Average annual return:  11.79%  
Starting investment:  $10,000.00  
Ending investment:  $17,458.82 
As shown above, the five year investment result worked out quite well, with an annualized rate of return of 11.79%. This would have turned a $10K investment made 5 years ago into $17,458.82 today (as of 10/02/2023). On a total return basis, that’s a result of 74.61% (something to think about: how might TRGP shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Targa Resources Corp paid investors a total of $8.91/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 exdate is used for the reinvestment of a given dividend).
Based upon the most recent annualized dividend rate of 2/share, we calculate that TRGP has a current yield of approximately 2.40%. 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 $58.38/share purchase price. This works out to a yield on cost of 4.11%.
