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

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a ten year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Illumina Inc (NASD: ILMN) back in 2013. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 05/15/2013
$10,000

05/15/2013
  $29,637

05/12/2023
End date: 05/12/2023
Start price/share: $70.37
End price/share: $208.60
Starting shares: 142.11
Ending shares: 142.11
Dividends reinvested/share: $0.00
Total return: 196.43%
Average annual return: 11.48%
Starting investment: $10,000.00
Ending investment: $29,637.41

The above analysis shows the ten year investment result worked out quite well, with an annualized rate of return of 11.48%. This would have turned a $10K investment made 10 years ago into $29,637.41 today (as of 05/12/2023). On a total return basis, that’s a result of 196.43% (something to think about: how might ILMN shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Another great investment quote to think about:
“When the public is most frightened, only the strong are left, and that’s when the market is in the best possible hands.” — Victor Niederhoffer
