For Tuesday October 6, TheStreet is paying close attention to two big companies coming out with their latest financial data as earnings season starts to pick up once again. PepsiCo (PEP) is slated to come out with its numbers before the market opens and then fast-food company Yum! Brands (YUM) releases its results after the market close. When PepsiCo reports its third-quarter fiscal 2015 earnings, analysts are calling for earnings of $1.27 a share on revenue of $16.22 billion. The stronger dollar is expected to weigh down on the global snack and beverage company's financial data. As a result, its international markets like Mexico, Russia and Brazil will likely see some headwinds. Wells Fargo analysts are also saying that soda and snacks volumes may be soft in the recent quarter. While earnings are expected to fall short of analysts' estimates.
