“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a decade-long holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Dollar Tree Inc (NASD: DLTR)? Today, we examine the outcome of a decade-long investment into the stock back in 2015.

Start date: 10/27/2015
$10,000

10/27/2015
  $15,723

10/24/2025
End date: 10/24/2025
Start price/share: $63.02
End price/share: $99.05
Starting shares: 158.68
Ending shares: 158.68
Dividends reinvested/share: $0.00
Total return: 57.17%
Average annual return: 4.63%
Starting investment: $10,000.00
Ending investment: $15,723.97

As we can see, the decade-long investment result worked out as follows, with an annualized rate of return of 4.63%. This would have turned a $10K investment made 10 years ago into $15,723.97 today (as of 10/24/2025). On a total return basis, that’s a result of 57.17% (something to think about: how might DLTR shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Here’s one more great investment quote before you go:
