Stocks rallied Friday as investors were encouraged by a cut in discount rates by the Fed.
"As long as we can stay out of the woods with further credit problems, we can build from this base and go forward steadily," said James Maguire, Sr., managing director at LaBranche. "I think we've hit the bottom. We might fish around here for a bit, but I'm very confident."

"There could be more near-term turbulence, but over the next 12 to 18 months, I think investors are going to look back and realize that today was a good day to get in the market."
Some market strategists were not as sanguine.
"As much as you don't want to fight the Fed, we're not so sure how many other shoes will drop in the marketplace," said John O'Donoghue, head of trading at Cowen & Company.
Leading Dow percentage gainers included JPMorgan Chase , Exxon Mobil and Alcoa .

"This is not a panacea for the problems that are in this economy," said Ned Riley, CEO of Riley Asset Management. "I'm very optimistic long-term, but we still have a systemic growth problem. I think the great anxiety right now is that the Fed may just inject this little bit of stimulus in, but then back away again because they fear inflation."
