Stocks ended little changed Wednesday, as uncertainty about Egypt hung over the market -- two days before the government's all-important jobs report.
"People are positioning for Friday's jobs report which will be exceedingly important -- the ADP number yesterday gave some hope that the number will be good, but we also need to set up for disappointment if it isn't," said Mark Luschini, chief investment strategist at Janney Montgomery Scott.
"The situation in Egypt is also turning a bit more violent and that's disturbing for investors as well, so we'll also be keeping an eye on that to see if it will spread," he added.
All of that uncertainty is likely to muffle any big gains Thursday, said Luschini.
"I wouldn't be surprised to even see the market drift lower today -- nothing dramatic but just as a symptom of having a good couple days earlier in the week and investors just being cautious going into tomorrow's report," he said.
