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

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a five year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Illumina Inc (NASD: ILMN) back in 2017, holding through to today.

Start date: 11/08/2017


End date: 11/07/2022
Start price/share: $211.20
End price/share: $217.19
Starting shares: 47.35
Ending shares: 47.35
Dividends reinvested/share: $0.00
Total return: 2.84%
Average annual return: 0.56%
Starting investment: $10,000.00
Ending investment: $10,283.15

As shown above, the five year investment result worked out as follows, with an annualized rate of return of 0.56%. This would have turned a $10K investment made 5 years ago into $10,283.15 today (as of 11/07/2022). On a total return basis, that’s a result of 2.84% (something to think about: how might ILMN shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more investment quote to leave you with:
“A 10% decline in the market is fairly common, it happens about once a year. Investors who realize this are less likely to sell in a panic, and more likely to remain invested, benefitting from the wealthbuilding power of stocks.” — Christopher Davis
