NEW YORK (TheStreet) -- Here are five ETFs to watch this week.SPDR S&P 500 ETF ( SPY) This week we kick off the second quarter of 2012. From an economic perspective, the first week of April is a busy one, particularly for the jobs picture. On Friday, all eyes will turn to the monthly nonfarm payroll report. The bar has been set high; during the past three months, we have enjoyed some solid signs of improvement on this front. History is on the market's side. Over the years, April has consistently proven to be a strong month for stocks. Nevertheless, although the market's strength and resilience during the opening months of the year have boosted confidence, patience is still warranted.
