“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a five year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Tesla Inc (NASD: TSLA) back in 2020: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full five year investment time horizon and then actually held for these past 5 years, here’s how that investment would have turned out.

Start date: 10/07/2020
$10,000

10/07/2020
  $31,972

10/06/2025
End date: 10/06/2025
Start price/share: $141.77
End price/share: $453.25
Starting shares: 70.54
Ending shares: 70.54
Dividends reinvested/share: $0.00
Total return: 219.71%
Average annual return: 26.17%
Starting investment: $10,000.00
Ending investment: $31,972.79

As shown above, the five year investment result worked out exceptionally well, with an annualized rate of return of 26.17%. This would have turned a $10K investment made 5 years ago into $31,972.79 today (as of 10/06/2025). On a total return basis, that’s a result of 219.71% (something to think about: how might TSLA shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more piece of investment wisdom to leave you with:
