Dow breaks the 500-point mark, putting blue chips on the right track since March

The Dow Jones Industrial Average recorded a strong rally on Tuesday at noon, putting the blue chips on the way to achieve the best gain in a day since March. The Dow

DJIA, + 2.20%

was up about 492 points, or 2%, to 25,739. If this gain were maintained, the gain would represent the best point and the best percentage since March 26. Tuesday's recovery was partly due to the sharp rise in the shares of the UnitedHealth Group component.

A H, + 4.51%

which produced a shock of about 70 points compared to the price-weighted equity gauge. The increase in shares for UnitedHealth comes after the health care company raised its earnings outlook for the entire year and said that it continued to see a growth in number of members and premiums of health care plans. Meanwhile, the S & P 500 index

SPX, + 2.21%

was up 2% to 2,804 and the Nasdaq Composite Index

COMP + 2.91%

2.6% increase to 7,620. Wall Street investors seem to be concentrating on optimistic earnings, particularly those of Goldman Sachs Group Inc.

GS + 3.13%

Johnson & Johnson

JNJ, + 1.91%

and Morgan Stanley

MRS, + 6.04%
