TORONTO, Oct 26 (Reuters) - Toronto's main stock index was little changed in wobbly trade on Wednesday morning, as concerns about the outcome of a summit on Europe's debt crisis offset encouraging U.S. economic data and North American earnings.
Research In Motion RIM.TO was among the big decliners, dropping 5.3 percent to C$21.38, after the BlackBerry maker said a software upgrade for its PlayBook tablet had been delayed until February, months behind schedule. [ID:nN1E79P0NF]
Other weighty decliners were Yamana Gold YRI.TO, off 5.1 percent to C$15.01, and Potash Corp (POT.TO: Quote), down 1.1 percent to C$48.69.
Base-metal miners were higher as copper prices rallied, with First Quantum Minerals (FM.TO: Quote), up 3.3 percent at C$17.77. [MET/L]
Canadian National Railway Co (CNR.TO: Quote) was the most influential gainer, rising 2 percent to C$76.60, after reporting a 19 percent jump in quarterly profit late on Tuesday. [ID:nN1E79J1VA] Continued...
