Bond insurer MBIA ( MBI) eventually fought its way into the green after saying in a conference call that it has enough cash to stay afloat -- more than $1.3 billion, all told, according to MarketWatch -- despite the currently harrowing market conditions.

Earlier, shares had tumbled after MBIA revealed it took a fourth-quarter loss of $2.3 billion, or $18.61 a share thanks to risky investments in second-lien mortgages and collateralized debt obligations squared (CDOs backed by other CDOs). That reverses a year-ago profit of $1.32 a share. Regardless, MBIA stock was recently bouncing 5.7% to $14.76.

Among the big winners was MasterCard ( MA), which said fourth-quarter income rocketed to $304 million, or $2.26 a share, on revenue that sprang 27.8% higher year over year to $1.07 billion. Exluding after-tax gains, EPS came to 89 cents a share. Analysts polled by Thomson Financial had called for a profit of just 72 cents a share on $984.8 million in revenue. Shares of the Purchase, N.Y., credit-card company were surging 14.4% to $216.20.

In earnings, Accuray ( ARAY) dove $5.48, or 36.6%, to $9.50 Thursday after the company gave second-quarter results shy of expectations and cut its full-year sales outlook.

Accuray said that because of credit market issues fewer customers ordered its CyberKnife robotic surgery system, used to aim radiation at tumors in difficult-to-target parts of the body. The company reported fiscal second-quarter earnings of $2.3 million, or 4 cents a share, vs. a loss of $7.3 million, or 45 cents a share, a year ago. (The recent quarter includes stock-based compensation costs of 7 cents a share.)

TiVo ( TIVO) added $1.97, or 29%, to $8.77 after a U.S. appeals court ruled that Dish Network ( DISH), formerly known as EchoStar Communications, infringed a TiVo patent and should pay TiVo $73 million in damages.

The decision from the U.S. District Court for the Eastern District of Texas settles the long-standing dispute between Echostar and TiVo, which had filed the suit in 2004.

Shares of Dish Network were down 15 cents to $28.24.

Amazon.com ( AMZN) rose $3.49, or 4.7%, to $77.70, a day after the company said it doubled its fourth-quarter profit and projected revenues for 2008 that were above analysts' estimates.

For the year, the company said it expects revenue between $18.75 billion and $19.75 billion. The Street's consensus estimate was $18.25 billion.

And, elsewhere, health-care products company Haemonetics ( HAE) said it earned $14.4 million, or 54 cents a share, vs. $16.9 million, or 62 cents a share, a year ago. But factoring out restructuring charges, the company said adjusted earnings came to 57 cents a share, on revenue that climbed 19% to $134.6 million.

Analysts polled by Thomson Financial expected a lesser profit of 53 cents a share on revenue of $124.6 million.

The company, which makes automated systems for blood donors, among other things, saw shares climb $4.64, or 9.4%, to $59.89.

Shares of Audible ( ADBL), a Newark, N.J.-based provider of audio content over the Internet, cranked 22.4% higher to $11.42 on news that Web retail giant Amazon.com ( AMZN) would buy the company for $300 million, or $11.50 a share.

Interactive Intelligence ( ININ), an Indianapolis-based maker of software for voice over Internet protocol (VoIP), reported fourth-quarter non-GAAP earnings of $3.1 million, or 16 cents a share, vs. $2.1 million, or 11 cents a share, in 2006. Analysts polled by Thomson Financial were expecting a per-share loss of a penny. Revenue for the quarter gained 23% from the year-ago period to $29.3 million. Shares gained 20.5% to $16.38.
