On CAPS, 30% of the 507 members who have rated GM believe the stock will underperform the S&P 500 going forward. These bears include hug1bear and All-Star kurtdabear, who is ranked in the top 15% of our community.

On Jan. 4, hug1bear seriously questioned GM:

I don't believe the company can gain any momentum against the entrentched competition. I don't see 'unique' in its offerings. Ford offers a better option for growth.

Over the next five years, in fact, GM is expected to grow its bottom line at pace of 10.3% annually. That's slower than competitors like Ford (17.7%), Honda (25.1%), and Toyota (56.3%).

CAPS All-Star kurtdabear elaborates on the bear case:

GM's next bankruptcy will be its last. The shameless hype the government used to peddle its shares to gullible investors would have been prosecuted in any private-party IPO.... This company's unfunded (and unfundable) future pension obligations alone are enough to sink it.
