Over on CAPS, fully 1,054 of the 1,309 All-Star members who have rated GM -- or 81% -- believe the stock will underperform the S&P 500 going forward. Among the entire bearish population are Gtrinvestor, who is ranked in the top 0.5% of our community, and Tenki2009.

Late last week, Gtrinvestor touched on GM's latest round of concerns: "Going concern opinion from their audit firm, the economy, they have never been run well, no focus (too many so-so brands all over the place) … the list goes on and on."

In a pitch from two days ago, Tenki2009 envisioned three ways the GM situation would play out (and none would bode well for common stockholders):

Case 1: GM declares bankruptcy (chapter 11 for now) - which, in my opinion, would be the best way for the company to restructure, unload their liabilities on many contracts with UAW, investors, etc.

Case 2: Government will continue to shovel money into GM over the next year or two (not just months) similar to AIG. Because the government loans will (eventually) have to be converted to equity to prevent GM's books from looking even worse (if that's even possible), common shares will be diluted to a value of (almost) nothing.

Case 3: Best case scenario for common share holders: Some healthier car company will buy GM, or at least GM's most valuable assets. Because of the large amount of debt GM is in, anybody's offer for GM would probably be very low (cents on the dollar) for both bonds and, especially, common stock.
