Stocks Log Weekly Gain Despite EU Worries

Stocks bounced off their lows Friday, but still ended in negative territory amid expectations of an imminent S&P ratings downgrade of several euro zone countries. Despite the day's losses, stocks still posted a gain for the week.

With stocks off their worst levels, some experts said the move implies that U.S. equities may have already priced in the negative news or are in the process of decoupling from Europe.

“We’re seeing more stabilizing in the U.S. and [equities are] being a lot less reactive to Europe as a lot more has been focused domestically,” said Daniel Penrod, senior industry analyst at California Credit Union League.

The Dow Jones Industrial Average finished lower, led by BofA and JPMorgan . Meanwhile, Chevron led the blue-chip gainers.

France will be downgraded by one notchby the S&P, according to the French Prime Minister. And in the latest move, Italy has been informed of an imminent S&P downgrade, according to the Italian news agency ANSA, citing unnamed government sources.

Meanwhile, the ratings agency is also expected to cut Spain and Portugal's credit ratings by two notches and downgrade Austria by one notch, according to French newspaper Les Echos, without citing its sources. The newspaper added that S&P would spare Germany, the Netherlands, Finland and Luxembourg from a downgrade.

Several other euro zone countries could face "imminent" downgradeby S&P, according to a senior euro zone government source. While the sources did not specify which countries will be affected, Germany is not included on the list. S&P declined to provide comment.

However, most traders appeared largely unfazed by the latest downgrade threats.

“This is not new news—we’ve been talking about these downgrades for months,” said Doreen Mogavero, president and CEO of Mogavero Lee & Company. “This is a headline reaction and not fundamental…you’re going to get volatility every time you have a significant headline.”

Adding to woes, talks between Greece and its creditors banks came to a halt, with Greeks warning of a possible collapseif no bond-swap deal is forged in the near-term. The negotiations had been expected to reach a conclusion next week.

“We’re getting a sense that this New Year is bringing hope that we’ve talked about for the last two years when our economy pushes forward,” said Penrod. “It’s very likely that we’ve bottomed and that we’re seeing the right trending and right growth.”
