“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 ten year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Illumina Inc (NASD: ILMN)? Today, we examine the outcome of a ten year investment into the stock back in 2013.

Start date: 10/31/2013


End date: 10/30/2023
Start price/share: $93.51
End price/share: $107.87
Starting shares: 106.94
Ending shares: 106.94
Dividends reinvested/share: $0.00
Total return: 15.36%
Average annual return: 1.44%
Starting investment: $10,000.00
Ending investment: $11,537.44

As we can see, the ten year investment result worked out as follows, with an annualized rate of return of 1.44%. This would have turned a $10K investment made 10 years ago into $11,537.44 today (as of 10/30/2023). On a total return basis, that’s a result of 15.36% (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.]
