Just a day before its historic return to the New York Stock Exchange, General Motors confirmed Wednesday that it would expand its initial public offering of common shares by 31 percent.

The company, responding to superheated investor demand for its stock, said it will raise the size of its IPO to 478 million common shares from the previously announced 365 million. Most of the common stock will be sold by the U.S. government, which is trying to unload what is now a 61 percent stake in the country's largest automaker.

The IPO, scheduled for Thursday, will cap a stunning resurrection for an automaker that nearly ran out of cash in 2008 and lost more than $80 billion in the four years leading up to its bankruptcy filing last year.

"This is, in my knowledge, one of the most remarkable turnarounds in corporate history," said Anant Sundaram, a finance professor at Dartmouth College's Tuck School of Business.

The most beloved capitalist in the world, Warren Buffett, has written another charming, thoughtful article in the New York Times.

And this one will make a lot of Americans furious.

Buffett's article is a "thank-you note" to our government, thanking them for the bailouts and emergency actions that Buffett says saved America from economic Armageddon two years ago.  Although people will always criticize the details, Buffett says, they can't criticize the outcome, which was remarkable:

"Uncle Sam, you delivered. People will second-guess your specific decisions; you can always count on that. But just as there is a fog of war, there is a fog of panic — and, overall, your actions were remarkably effective."

Buffett makes a compelling case that, if the government had done nothing in the financial crisis, the financial system and economy might have collapsed, at least temporarily.  And given that the system did NOT collapse, the government's intervention certainly was commendable.

But, as many people have already pointed out, no one benefited more from the bailouts than Warren Buffett, so it's no surprise that he's grateful.  Most bailout critics, furthermore, don't suggest that the government should have sat around and done nothing--they argue that the government's intervention should have been more fair and effective, particularly with respect to Wall Street.

Mortgage applications fell sharply last week as mortgage rates pushed higher.

The volume of mortgage loan applications decreased 14.4% on a seasonally adjusted basis in the week ending Nov. 12, the Mortgage Bankers Association said early Wednesday.

Refinancing applications decreased 16.5% from the previous week to the lowest level observed since July. New-home purchase loan applications decreased 5% week-over-week, the first decrease after three consecutive weekly increases.

"Rates increased sharply last week due to stronger economic data and lingering uncertainty regarding the structure and impact of the Fed's QE2 program," said Michael Fratantoni, MBA's Vice President of Research and Economics. "Mortgage applications, particularly for refinances, dropped in response."

U.S. stocks fell on Thursday, led by technology losses as Cisco Systems Inc's weak outlook fueled worries that economic softness will hurt profits.

Cisco's shares lost 16 percent to $20.57 after the Internet network product provider's CEO, John Chambers, cautioned about "short-term challenges" in Europe and public-sector spending. Late Wednesday, the company forecast revenue and earnings well below estimates.

On a percentage-loss basis, if Cisco closes at that level, this would be the worst one-day percentage drop since July 14, 1994, when Cisco slid 17.71 percent, according to Thomson Reuters Datastream.

Howard Silverblatt, an analyst at Standard & Poor's, said this was set to be the biggest one-day dollar loss ever for Cisco's stock.

By early afternoon, 385 million shares of Cisco had traded, making this one of the 10 busiest days in the history of the stock.

The warning from Cisco also dragged down shares of other tech heavyweights: Microsoft, down 1.7 percent at $26.48; Hewlett-Packard, down 3 percent at $42.83, and Juniper Networks, down 0.4 percent at $34.40. The drop in Cisco's stock reduced its own market value by about $21 billion in early trading, according to S&P.

The Dow Jones industrial average .DJI fell 91.27 points, or 0.80 percent, to 11,265.77. The Standard & Poor's 500 Index .SPX shed 7.73 points, or 0.63 percent, to 1,210.98. The Nasdaq Composite Index .IXIC dropped 27.85 points, or 1.08 percent, to 2,550.93.

Analysts saw the outlook as worrisome, particularly since profit growth for technology companies this reporting period has outperformed the broader S&P 500.

U.S. lender Bank of America says it is owed $160 million on unpaid insurance claims made on failed mortgages, court papers say.

In a lawsuit filed in Charlotte, N.C., the banking giant says Old Republic Insurance Co. has denied "thousands" of valid claims and is making excuses not to cover them.

The lawsuit says from 2009 to 2010 claims honored by Old Republic fell 75 percent. Old Republic, in turn, said it was turning down claims with inadequate paperwork, The Charlotte Observer reported Thursday.

With Bank of America already caught in a controversial review of foreclosures brought on by numerous court challenges over flawed documents, "This is just another phase of the crisis," said Keith Gumbinger, vice president of mortgage analysis at HSH Associates.

Bank of America said faulty paperwork has "nothing to do" with the reason Old Republic is failing to honor mortgages it insures.

BofA says it continues to pay Old Republic's premium of $870,000 each month to cover "a percentage" of its loans.
