Oilfield firms Baker Hughes BKR.O and Schlumberger SLB.N report next week. By Lewis Krauskopf NEW YORK, Jan 13 (Reuters) - Shares of U.S. energy companies are soaring in the early days of 2022, driven by a shift to so-called value stocks and assets that stand to benefit from the steepest inflation in nearly four decades. The sector’s outperformance also reflects a broader shift from tech and high-growth stocks that jumped last year to companies that stand to benefit from higher Treasury yields, as surging inflation increases expectations the Federal Reserve will be more aggressive in normalizing monetary policy.
