“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
A long holding period can produce very different outcomes depending on the balance between share-price performance and dividends. For Occidental Petroleum Corp (NYSE: OXY), a 20-year investment made in 2006 generated a positive total return, but the result depended heavily on dividend reinvestment rather than stock appreciation alone.
Using dividend-adjusted return data, a $10,000 investment in Occidental Petroleum on 08/07/2006 would have grown to $18,965.03 by 08/06/2026, assuming all dividends were reinvested. That equates to a total return of 89.60% and an annualized return of 3.25%.

In simple terms, Occidental Petroleum delivered a modest long-term compound return over this period. The stock price itself rose only from $51.40 to $56.04, so most of the gain came from cash distributions that were reinvested over time. That distinction matters: total return can look materially better than price return when a company pays meaningful dividends across a long holding period.

What Drove the Return
Occidental Petroleum paid a cumulative $33.75 per share in dividends during the 20-year holding period. Reinvesting those dividends increased the share count from 194.55 to 338.33 shares, which is a significant part of the ending value. Without reinvestment, the outcome would have been substantially weaker because the share price appreciation over the full period was limited.
This illustrates a core feature of long-term equity returns in mature, cyclical industries: investor outcomes are often shaped by the interaction of three variables rather than by price alone.
- Starting valuation: the price paid at the beginning of the holding period affects how much future business performance is already reflected in the stock.
- Cash returned to shareholders: dividends can provide a meaningful portion of total return, especially when reinvested consistently.
- Industry cyclicality: commodity-sensitive businesses can experience long stretches of volatility, which can compress long-term annualized returns even when absolute returns remain positive.
Occidental Petroleum and Energy-Sector Cyclicality
Occidental Petroleum operates in a sector where earnings, cash flow, and valuation are closely tied to oil and gas prices. That makes long-term return analysis more complex than a simple beginning-to-end price comparison. Over a 20-year period, energy companies can move through multiple commodity cycles, including periods of strong free cash flow, balance-sheet strain, dividend changes, and capital-allocation resets.
For that reason, a 3.25% annualized return over two decades says as much about the path of the business and the sector as it does about the endpoint. Investors reviewing OXY’s historical performance should distinguish between operational strength at different points in the cycle and the return earned by shareholders from a specific entry price.
Current Yield and Yield on Cost
Based on the most recent annualized dividend rate of $1.04 per share, OXY has a current yield of approximately 1.86% using the ending share price of $56.04.
Another useful measure is yield on cost, which compares the current annual dividend to the original purchase price. Using the 2006 entry price of $51.40 per share, the current $1.04 annualized dividend translates to a yield on cost of 3.62%.
Key figures at a glance:
- Initial investment: $10,000
- Ending value: $18,965.03
- Total return with dividends reinvested: 89.60%
- Annualized return: 3.25%
- Cumulative dividends paid per share: $33.75
- Current yield: 1.86%
- Yield on original cost: 3.62%
Bottom Line
A 20-year investment in Occidental Petroleum produced a positive result, but not a high one by long-term equity standards. The historical record here reinforces an important point: in cyclical dividend-paying stocks, reinvested distributions can account for much of the shareholder return when capital appreciation is muted over extended periods.
