Despite corporations and nations alike increasingly emphasizing their goals to rely less on fossil fuels, in 2022 oil companies are on track to reap huge profits. The energy shortage created by Russia’s invasion of Ukraine triggered a spike in oil prices internationally, and the commodity became more valuable than ever. “The world economy is not ready to abandon fossil fuel,” explained Craig Brothers, senior portfolio manager at Bel Air Investment Advisors. “Russia provides 41% of Europe’s natural gas needs which is critical to heat homes in the winter.”

In March, oil prices spiked to a record high of over $130 per barrel, leading many companies to lock in fat profits. Eight out of the top 10 stocks in the S&P 500 (as measured by stock price appreciation) are energy companies, and 7 out of 10 are oil producers.

Will energy stocks keep going up? According to financial advisors who spoke with Fortune, the sector is still positioned for an upwards trajectory even as stock prices have declined slightly from market highs this summer. “I find that many investors are still under-exposed to the energy sector, and not just oil and gas, but green energy as well,” Adrian Helfert, chief investment officer at Westwood, told Fortune. Brothers thinks energy costs will remain inflated. “We expect higher energy prices to persist and prevent inflation from returning to the Fed’s goal of 2%,” he said. The S&P 500 energy group has been up 26.5% year to date. Here are the top performing stocks so far this year.
