“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 2013, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 08/23/2013
$10,000

08/23/2013
  $56,592

08/22/2023
End date: 08/22/2023
Start price/share: $23.89
End price/share: $135.16
Starting shares: 418.59
Ending shares: 418.59
Dividends reinvested/share: $0.00
Total return: 465.76%
Average annual return: 18.92%
Starting investment: $10,000.00
Ending investment: $56,592.02

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 18.92%. This would have turned a $10K investment made 10 years ago into $56,592.02 today (as of 08/22/2023). On a total return basis, that’s a result of 465.76% (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.]

One more investment quote to leave you with:
“Unless you can watch your stock holding decline by 50% without becoming panic-stricken, you should not be in the stock market.” — Warren Buffett
