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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five 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 five year investment into the stock back in 2019.

Start date: 04/08/2019
$10,000

04/08/2019
  $3,948

04/05/2024
End date: 04/05/2024
Start price/share: $323.61
End price/share: $127.75
Starting shares: 30.90
Ending shares: 30.90
Dividends reinvested/share: $0.00
Total return: -60.52%
Average annual return: -16.97%
Starting investment: $10,000.00
Ending investment: $3,948.18

As shown above, the five year investment result worked out poorly, with an annualized rate of return of -16.97%. This would have turned a $10K investment made 5 years ago into $3,948.18 today (as of 04/05/2024). On a total return basis, that’s a result of -60.52% (something to think about: how might ILMN shares perform over the next 5 years?).
