Think back a couple of years ago. Smart money for little guys like us said stay away from ETF's. I believed it then and I still believe it. Strictly for day traders. Guys like Blackrock are really pushing them because they are making tons off them, but not the people they are selling to, the buy and hold folks, even if it's just for a month or two. Pick a couple out and follow them for a couple of qtrs, I guarantee you will lose money.
