“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 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 decade-long holding period for an investor who was considering T-Mobile US Inc (NASD: TMUS) back in 2009, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 12/28/2009
$10,000

12/28/2009
$61,598

12/24/2019
End date: 12/24/2019
Start price/share: $15.64
End price/share: $77.32
Starting shares: 639.39
Ending shares: 796.52
Dividends reinvested/share: $4.06
Total return: 515.87%
Average annual return: 19.95%
Starting investment: $10,000.00
Ending investment: $61,598.43

As we can see, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 19.95%. This would have turned a $10K investment made 10 years ago into $61,598.43 today (as of 12/24/2019). On a total return basis, that’s a result of 515.87% (something to think about: how might TMUS 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 T-Mobile US Inc has paid $4.06/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 .6875/share, we calculate that TMUS has a current yield of approximately 0.00%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .6875 against the original $15.64/share purchase price. This works out to a yield on cost of 0.00%.

One more piece of investment wisdom to leave you with:
