Occidental Petroleum Corporation

Warren Buffett began accumulating OXY in 2022 and has since built Berkshire Hathaway's position to over 28% of the company. This is not a passive index holding — Buffett has received regulatory approval to acquire up to 50%, signaling potential for further accumulation. The Berkshire presence creates an unusual dynamic: when OXY sells off sharply, there is a reasonable probability that Berkshire is buying on the dip, which creates a quasi-floor.

For traders, the Berkshire angle means two things: first, OXY is less likely to experience the catastrophic drawdowns that plague smaller energy names because institutional confidence in the management team is elevated; second, news of Berkshire buying more shares (disclosed quarterly in 13F filings and monthly in 13D/A amendments) can act as a positive catalyst.

OXY's earnings and free cash flow are tightly correlated with West Texas Intermediate (WTI) crude oil prices. When WTI is above $70-75, OXY generates strong free cash flow and can fund dividends, buybacks, and debt repayment simultaneously. Below $60, the calculus changes and capital allocation becomes more constrained.

Traders who follow energy sector rotation setups use WTI direction as the primary filter. When WTI is trending up and XLE is breaking out, OXY is often one of the higher-conviction longs within the sector because of its Permian Basin concentration and Berkshire backing. When WTI reverses, OXY typically holds better than pure-exploration peers.

Energy stocks including OXY tend to outperform when inflation is rising and the Fed is in a tightening cycle. Higher oil prices feed into CPI readings, and OXY's revenue benefits directly. This makes OXY a natural macro hedge for portfolios that are long technology stocks — when tech sells off on rate-hike fears and energy rallies on inflation, the two positions partially offset each other.

OXY also has an expanding carbon capture and storage business (1PointFive) that Buffett specifically cited as part of his investment thesis. While this segment is currently small, positive regulatory developments for carbon capture could provide a separate catalyst that is not correlated with crude oil prices.
