[centsgirl]

The S&P 500 failed to break a key technical resistance level for the second day on Tuesday as low trading volume raised more questions about the market's strength.

The broader market index closed slightly below 1,333, a closely watched level as it represents a doubling from the low reached in March of 2009.

Trading volume was low with just 7.03 billion shares traded on the New York Stock Exchange, compared with last year's estimated daily average of 8.47 billion dollars.

A re balancing of the Nasdaq 100 .NDX, which will take effect on May 2, spurred traders to buy companies with increased weightings, this includes Microsoft Corp,and the Intel Corp also included is Cisco Systems Inc , they all rose about 1 percent.
