I see the volume on GM is over 100,000,000. Why would anyone even consider buying GM?

are they NOT a ticking timebomb when it comes to bankruptcy.
...............................................................................
Although I completely disagree with the rationale for buying GM, short term traders are buying the stock to take advantage of volatility. The shares will essentially be voided out when they inevitably declare bankruptcy within the next 2 weeks, but some traders are willing to take the risk for quick short term gains in the interim.

Ultimately it is a suckers game.

Also many investors see only two things: 1) really cheap stock price they think they can afford, and 2) other companies that have gone through bankruptcy are still in business (example: Airlines) and the stock price is now much higher. What they don't understand is that many times it is a new company that comes out of bankruptcy (example United Airlines is now UAL Inc.), and they don't understand that their cheap "old" stock will be cancelled as worthless and "new" shares issued will not be given to them but sold at a much higher price.
