U.S. and European stock futures edged lower Wednesday, a reflection of growing investor unease ahead of a high-stakes group of earnings and inflation readings. Dow shed 0.2%, S&P 500 shed near 0.3%, and Nasdaq 100 shed 0.3%, a reflection of a risk-off theme that was running itself through globally. In Europe, the FTSE 100 faces a tentative start after having weakened near its record high of 9,000, which was based on spill-over anxiety from U.S. headline inflation readings and today's U.K. CPI report. Markets were absorbing Tuesday's 0.3% monthly U.S. CPI, which was above market estimates but reinforced the thinking that for the moment, at least, inflation is stuck.
