“Someone’s sitting in the shade today because someone planted a tree a long time ago.”
— 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 two-decade holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Centene Corp (NYSE: CNC) back in 2005. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:
| Start date: | 10/31/2005 |
|
|||
| End date: | 10/28/2025 | ||||
| Start price/share: | $5.04 | ||||
| End price/share: | $33.19 | ||||
| Starting shares: | 1,984.13 | ||||
| Ending shares: | 1,984.13 | ||||
| Dividends reinvested/share: | $0.00 | ||||
| Total return: | 558.53% | ||||
| Average annual return: | 9.88% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $65,839.29 | ||||
As shown above, the two-decade investment result worked out well, with an annualized rate of return of 9.88%. This would have turned a $10K investment made 20 years ago into $65,839.29 today (as of 10/28/2025). On a total return basis, that’s a result of 558.53% (something to think about: how might CNC shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
