Stocks were set to rally at Friday's open, after the government reported that the economy added 244,000 jobs in April, much better than expected.
The unemployment rate ticked higher to 9% from 8.8% but investors were clearly tuned into the top-line number.  Economists were expecting the report to show that employers added only 185,000 jobs in the month and the unemployment rate to remain 8.8%.

Commodities: Oil, gold, and silver continued to slide Friday.
Just a week ago, silver prices were within spitting distance of breaching $50 an ounce. On Friday, silver futures for July delivery dropped $2.45, or 7%, to $33.80 an ounce.
Gold futures for June delivery fell $2.20 to $1,479.20 an ounce.
Oil for June delivery slipped $2.02, or 2%, to $97.78 a barrel, after plunging 8.6% to close below $100 a barrel Thursday.
