Wall Street may not get its expected rebound

Normally a big decline would set up Wall Street for a technical rebound.

But that may not be the case this week, even after the market last week posted its worst weekly loss for the year and the S&P fell for six straight sessions.

With the corporate earnings season drawing to an end and recent US economic data raising doubts about the pace of growth, the S&P 500, which is down 7.3% so far in May, could decline further this week as concerns about the health of Europe persist.
