This earnings season is of particular interest to investors, given the spike in earnings warnings that have occurred in previous weeks as companies admitted to their struggles amid the current global economic turmoil. One of the more notable negative preannouncements was from Procter & Gamble (NYS: PG) , which cut organic sales growth estimates by 2% for the current quarter following market-share losses and an inability to pass along price increases successfully. Investors will have to wait until Aug. 3 to find out where results actually ended up, and they'll also receive an update on the company's fiscal 2013 guidance.

Leading off for Dow components is aluminum producer Alcoa (NYS: AA) , which releases earnings after the market closes today. With aluminum prices sitting near two-year lows, Alcoa's smelting unit has been hurting, while its fabrication business, which provides specialized aluminum for the likes of Ford (NYS: F) , has been performing nicely, given the tailwind provided by the world's automakers. According to some estimates, shipments of aluminum from the U.S. to auto industry customers will rise by more than 15% this year. According to our industrials analyst in this premium report on Ford, we can expect that kind of growth to persist, thanks to a number of factors moving in the company's favor.

On the other hand, Alcoa's struggles in its smelting unit reflect the difficulties of operating a commodity business, where there is only so much a company can do in response to supply-and-demand imbalances. Another route investors can take is finding companies with an innovative product that has few competitors. In this special free report, "Discover the Next Rule-Breaking Multibagger," our analysts outline one such company that is changing the way business is done for its customers.
