NEW YORK (TheStreet) -- Here are five ETFs to watch this week.Financial Select Sector SPDR ( XLF) Earnings season will get underway on Tuesday when aluminum giant Alcoa ( AA) steps up to the plate. Throughout the opening months of 2012, global macroeconomic factors have dominated discussions. In the coming weeks, however, some of this attention should shift to the various companies slated to release their performance numbers and outlooks. The financial sector will be of particular interest this week. Both JPMorgan ( JPM) and Wells Fargo ( WFC) are on tap for Friday. These two behemoths top off a number of financial sector ETFs. In XLF, for instance, the duo account for a nearly 20% slice of its assets.
