TheStreet's Action Alerts PLUS Portfolio Manager and Host of CNBC's Mad Money Jim Cramer said Alcoa is set to report quarterly results on Monday after the closing bell, but already it's 'a stock that nobody wants to own right now.' Cramer said the results are likely to be poor because of China and the decline of aluminium sales there. Despite what will likely be a slowdown in China, Cramer thinks the aerospace part of the business still has growth potential. Eventually, Cramer believes the company will be split into two in an effort to unlock shareholder value. Alcoa shares, which are currently trading in the $8 range will likely take a hit and Cramer believes that's a buying opportunity.
