Stocks rise as optimism about US economy grows (AP)

Stocks rose early Friday as spending cuts by Italy lifted traders' hopes about Europe's progress toward taming its debt crisis. A flat reading on U.S. inflation sent bond yields lower.

World markets rose Friday after Italy's lower house of parliament approved an austerity package in hopes of lowering the country's escalating borrowing costs.

The Dow Jones industrial average is up 58 points, or 0.5 percent, at 11,926 in the first half-hour of trading. The Standard & Poor's 500 index is up 8, or 0.7 percent, at 1,224. The Nasdaq composite index is up 22, or 0.9 percent, at 2,563.

The gains were broad. Nine of the 10 industry groups in the S&P 500 index rose, led by industrial and technology companies. Telecommunications was the only sector to fall, by 0.3 percent.

The yield on the 10-year Treasury note plunged to 1.88 percent from 1.93 percent earlier Friday after the government said consumer prices were unchanged last month, suggesting that inflation remains low. Low inflation makes bonds more attractive because it doesn't diminish the buying power of the fixed return a bond provides over time.

BlackBerry maker Research In Motion Ltd. plunged 12 percent after the company said late Thursday that new phones seen as critical to the company's future will be delayed until late next year. The company is also taking a big loss on unsold tablet computers and predicted that its BlackBerry sales will fall sharply during the holiday period.

If stocks hold their gains, it will be only be the second up day this week. Indexes rose Thursday after positive economic news brought relief to choppy markets. The Dow rose 45 points after separate reports showed sharply fewer layoffs and better business conditions for factories on the Eastern seaboard.

World markets followed U.S. markets higher Friday as the European debt crisis failed to produce any worrying headlines. Bad news out of Europe has overshadowed positive economic news for months.

Italy's austerity measures are seen as a crucial step toward soothing fears about Europe. The nations' borrowing costs have risen in recent weeks to levels at which other nations, such as Greece, were forced to take bailouts.

The cuts are aimed at persuading bond traders that Italy can emerge from the widening crisis without defaulting on its debts. The nation still sits on a $2.5 trillion powder keg of debt that could cause a global economic recession if it defaults.

Stocks mostly rose in Europe following gains in Asia. Britain's FTSE added 0.5 percent and Italy's benchmark index rose 0.4 percent.

Online game developer Zynga Inc. begins trading later Friday on the Nasdaq. The San Francisco company, which specializes in Facebook games, priced its initial public offering late Thursday at $10 per share, raising $1 billion. It's the largest Internet IPO since Google Inc. went public in 2004.

Among companies making big moves:

? New York-area cable TV provider Cablevision Systems Corp. plunged 14 percent, the most in the S&P 500, following the sudden departure of its chief operating officer, Tom Rutledge.

? Adobe Systems Inc. jumped 8.4 percent, the most in the S&P 500, after the software maker reported earnings and revenues that were far ahead of what analysts were expecting. Analyst Walter Pritchard at Citigroup said the quarter was a "blow-out when most expected weakness."
