Stocks set for another lower start

Stocks were set to start lower yet again as Wall Street's attempt for a second straight week of gains is challenged. Investors continued to be concerned about the economy, and reports from such companies as Palm and Sony Ericsson didn't help much.

[Update 8:30: Stock futures changed direction and are now indicating stocks could start higher as investors take in the more positive data on the economy and hope the low mortgage rate could help the housing market.]
