“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: 08/28/2020
$10,000

08/28/2020
  $23,693

08/27/2025
End date: 08/27/2025
Start price/share: $147.56
End price/share: $349.60
Starting shares: 67.77
Ending shares: 67.77
Dividends reinvested/share: $0.00
Total return: 136.92%
Average annual return: 18.83%
Starting investment: $10,000.00
Ending investment: $23,693.57

As shown above, the five year investment result worked out exceptionally well, with an annualized rate of return of 18.83%. This would have turned a $10K investment made 5 years ago into $23,693.57 today (as of 08/27/2025). On a total return basis, that’s a result of 136.92% (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.]

Here’s one more great investment quote before you go:
“The right time for a company to finance its growth is not when it needs capital, but rather when the market is most receptive to providing capital.” — Michael Milken
