** Steelmaker ArcelorMittal MT.AS falls about 3% after the first-quarter results of some of its divisions came in below market expectations
** Though the Luxembourg-based company's core earnings were in line with what J.P. Morgan expected, its European and Mining businesses came below forecast by the brokerage
** Earnings for Europe and Mining were 7% and 19% below the brokerage's estimates
** "We move to an underweight rating ... ArcelorMittal's market value does not adequately discount potential negative impacts arising from higher global energy prices," J.P. Morgan says
