S&P 500 sets record

For the second time in less than a month, the American stock market marched past another milepost on its long, turbulent journey back from the Great Recession, toppling another record left over from the days before government bailouts and failing investment banks.

The Standard & Poor’s 500 closed at a new high Thursday, three weeks after another popular market gauge, the Dow Jones industrial average, obliterated its own closing record.
