The world is in the middle of a historic oil crisis, yet the biggest bargains on Wall Street can be found in U.S. energy stocks. The price of the energy basket in the S&P 500 is just 2% higher than where it was before the war, when oil futures were close to $70 a barrel and the world had a supply glut. Today, oil prices are closer to $100 a barrel and the world has lost roughly a billion barrels of oil supply.
