Investing.com — Shares in Occidental Petroleum Corporation (NYSE:OXY) gained nearly 3% in premarket U.S. trading on Wednesday after billionaire Warren Buffett’s Berkshire Hathaway (NYSE:BRKa) increased its already hefty stake in the energy company.
The Omaha, Nebraska-based conglomerate purchased 5.8 million shares in Occidental from March 3 to March 7, according to a regulatory filing, all within the range of $59 to $61 per share.
Berkshire’s indirect ownership of the Houston-based group now totals more than 200 million shares, worth $12.2 billion based off of the stock’s closing price of $60.85 on Tuesday.
Last August, regulators gave Berkshire the approval to snap up a 50% stake in Occidental, spurring speculation that it may eventually buy all of the business. The stake currently stands at more than 22%.
Occidental is among Berkshire’s ten largest holdings, a list that also includes oil major Chevron (NYSE:CVX) as well as blue-chip corporate names like Bank of America (NYSE:BAC) and Coca-Cola (NYSE:KO).
