As far as I can tell, these two have a tentative relationship at best—and are likely headed for some rocky times ahead." * Morning Call: U.S. futures signal losses, London opens flat, European shares keep falling, the Nikkei hits an 8-week low and Hong Kong hits 7-week mark. * The FT has lunch with Larry Summers. * Is anyone willing to call an M&A market bottom? * The trial of Refco lawyer Joseph Collins is over, but not before one juror threatened to cut off another juror's finger.
