Vanguard Total Stock Market ETF (VTI)

A broad market index so if you want to look at a single ETF to give you a core holding in your portfolio, this is as good as any. You are really looking at a broad basket of world stocks. He would prefer something that is a little more narrowly focused. You can buy the S&P 500 and get really good exposure to the US. You could buy EAFEs (XIN-T). These 2 along with TSX 60 (XIU-T) and an emerging market ETF and rebalancing once a year and you would probably be better off. If you don’t have a lot of money to do that, maybe you are better off just to buy this one.

If you want to be in the US and you don’t want to worry about the Russell 2000, the mid-caps, etc. buy this. It has had a terrific run and will probably continue to do well. It basically owns everything.
