“I buy on the assumption that they could close the market the next day and not reopen it for five years.”
— Warren Buffett
One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a five year holding period for an investor who was considering Occidental Petroleum Corp (NYSE: OXY) back in 2020, bought the stock, ignored the market’s ups and downs, and simply held through to today.

| End date: | 09/05/2025 | ||||
| Start price/share: | $11.06 | ||||
| End price/share: | $45.91 | ||||
| Starting shares: | 904.16 | ||||
| Ending shares: | 950.28 | ||||
| Dividends reinvested/share: | $2.66 | ||||
| Total return: | 336.28% | ||||
| Average annual return: | 34.31% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $43,635.48 | ||||
As shown above, the five year investment result worked out exceptionally well, with an annualized rate of return of 34.31%. This would have turned a $10K investment made 5 years ago into $43,635.48 today (as of 09/05/2025). On a total return basis, that’s a result of 336.28% (something to think about: how might OXY shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Occidental Petroleum Corp paid investors a total of $2.66/share in dividends over the 5 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).
Based upon the most recent annualized dividend rate of .96/share, we calculate that OXY has a current yield of approximately 2.09%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .96 against the original $11.06/share purchase price. This works out to a yield on cost of 18.90%.
