Index futures and bullion were quiet Sunday night, apparently unable to find an excuse to rally on news that Kim Kardashian and Kanye West are expecting a girl. When stocks open Monday morning we may find out whether Friday’s selloff was simply “technical,” or whether instead there may concerns sufficient to slow down the rampaging bull. Europe’s deepening recession, China’s dramatic slowdown, and now a push in long-term yields above 4% that could put the kibosh on the Fed’s real estate bubble are indeed developments about which Wall Street ought to be concerned.
