On today’s Wall Street Confidential video on TheStreet.com Jim Cramer noted Alcoa (AA).  Cramer said this was an undermanaged company and this might not be able to be resisted; it’s a country club that needs to change.  Cramer thinks Rio Tinto (RTP) is the more likely buyer.  On 3M (MMM) Cramer doesn’t like the buyback; the quarter was really bad and they are selling the good properties to maintain its bad ones.  The buyback isn’t a good one because the business isnt well run; he’d take the profit on the pop.   On General Motors (GM) Cramer said it has decided to be a small company and GM might want to consider Chrysler if DaimlerChrysler (DCX) spins it out because it could be am interesting buy for GM.  GM can make more money as a smaller auto maker than as the largest, so that contradicts the ‘smaller company’ depending on how you take it.
