On CAPS, 94% of the 3,463 members who have rated Alcoa believe the stock will outperform the S&P 500 going forward. These bulls include piranha60565 and dougherty7.

Late in September, piranha60565 tapped the stock as a solid turnaround opportunity: "Aluminum is making a comeback and [Alcoa] will benefit the most. Competition in China is tough but I trust their management and experience."

Over the next five years, in fact, Alcoa is expected to grow its bottom line at a brisk rate of 37% annually. That's much faster than competitors like BHP (16%), Rio Tinto (9%), and Vale (7%).

CAPS member dougherty7 expands on the big trend working in Alcoa's favor:

I expect aluminum to become increasingly important to automakers. Fuel economy regulations are set to ramp up aggressively over the next 10-20 years. When tweaking the engine leaves a car short of the industry requirement, the automaker will have no choice but to save weight. Aluminum's strength and lightness will make it a crucial part of every car.
