On CAPS, 27% of the 117 members who have rated A123 believe the stock will underperform the S&P 500 going forward. These bears include All-Stars jimbopicks and TMFDeej, both of whom are ranked in the top 15% of our community.

Late last month, jimbopicks noted that A123 is "consistently unprofitable in an industry with many major players that does not currently have significant business potential." Our All-Star concludes: "Although the long term prospects will be strong for the firm if they can partner with a major automotive company, the short term will be a struggle."

In a pitch from two weeks ago, TMFDeej also advised Fools not to get charged up:

A123 loses money on every unit that they sell. They have a short client list, that's going to get even shorter in the near future.

This is a win big / lose big stock. If, and this is a tremendous if, the company is successful in developing an excellent battery for use in plug-in electric vehicles or a storage device for solar / wind power it has the potential to be a big winner. The government certainly wants them to be successful, it's pouring tons of money into the company.

I am betting however that the stiff competition from larger, better funded, established foreign competition in the battery area will develop better products than this U.S. start-up.
