The financial crisis, employment market and social media explosion have converged, providing a new level of clarity into what is happening in the world around us. Where was ground zero for this financial catastrophe? Well, according to the LinkedIn blog, five companies have shown the most action: Barclays (BCS), Credit Suisse (CS), Citigroup (C), Bank of America (BAC) and JPMorgan Chase (JPM). Interestingly, Goldman Sachs (GS), among the biggest winners now that we're pulling out from the recession, didn't see as much play.

JPMorgan Chase (JPM) wanted a piece of what could be the most interesting insurance IPO of the year, but it won't get a taste.

American International Group's (AIG) Asian life insurance unit, American International Association, is going to go public in Hong Kong for an estimated $10 billion, and JPMorgan isn't being allowed to play, insiders say, because of a sour relationship that stretches back to the September 2008 financial crisis. As a result, it will be the only major investment bank not being admitted to the party.

UBS (UBS) was one of the hardest hit from the financial crisis, but the company is showing signs of stabilization. In the latest quarterly report, the firm posted profits of $1.3 billion. Actually, it was the first reported profit in a year.

Of course, the cost-cutting was a big help (roughly 16% of the workforce). But there was also a nice tax credit during the quarter.

The company's new CEO, Oswald Grübel, definitely understands how to turnaround financial institutions. After all, he had considerable success at Credit Suisse (CS).

When it comes to snowplows and salt spreaders for light trucks, Douglas Dynamics has top-notch brands in the industry. They include Western, Fisher and Blizzard.

Now, Douglas has filed to go public. The estimated size of the offering is about $150 million.

October seems to have been a good month for consumer spending. Unemployment is holding consumers back, but it isn't keeping wallets clamped shut.

A Bloomberg survey reveals that purchases grew 0.5% last month, based on the thoughts of 61 economists. The U.S. Department of Commerce is releasing its report on Wednesday. In advance of this news, Bloomberg's survey suggests that there are signs of slight improvement.

Banking crisis? Well, banks continue to post profits. Look at Barclays PLC (NYSE: BCS), which today reported a $3.15 billion profit for the first half of 2009.

Why the growth? Interestingly enough, Barclays got a big boost from its investment banking division (which is focused on mergers & acquisitions, public offerings and capital raises). Keep in mind that the company purchased the U.S. operations of Lehman Brothers.

And the strength is no fluke. Other major banks -- such as Goldman Sachs (NYSE: GS), Credit Suisse (NYSE: CS) and JPMorgan Chase (NYSE: JPM) -- also posted strong results with investment banking.

The complicated legal fight over the implosion of the private equity buyout of Huntsman (NYSE: HUN) has been settled. The firm was able to get $632 million in cash and $1.1 billion in financing from Credit Suisse (NYSE: CS) and Deutsche Bank (NYSE: DB).

Basically, Huntsman claimed that these financial firms failed to uphold their responsibilities in backing the takeover from Hexion Specialty Chemicals, which was struck in July 2007 at $28 per share. Now, Huntsman is trading at $5.92, primarily because of the plunge in the global chemicals sector.
