Corporate earnings are once again running the show. This morning, stock futures are edging higher as investors brace for another wave of quarterly results and a crucial inflation report tomorrow. The mood is not euphoric, but it is steadier than it was 24 hours ago. Wednesday's stronger-than-expected jobs report - 130,000 jobs added in January, unemployment dipping to 4.3%, wages holding firm - helped ease fears of an imminent economic slowdown. In recent weeks, markets have oscillated between worrying about overheating and worrying about stalling. For now, the data suggest neither extreme.
