Couch potato investing

Well I realized that 2009 flew by with 90% of our money sitting in cash rotting away earning measly interest. The other 10% is invested in BNS which has done well since I got in around $35 (currently at about $46), so that makes me feel a bit better. However, I still I feel that I should be doing more but I’m not exactly feeling confident about investing more in equities at this point. So a couch potato portfolio seems like a good place to start. The concept of a Couch Potato Portfolio is nothing new. It’s fairly straightforward, invest in some diversified low cost index funds or ETFs and re-balance once a year. Here are some articles and posts I found helpful:

• Million Dollar Journey’s A Simple Low Cost Diversified ETF Portfolio and RESP Strategy
• Canadian Capitalist’s Sleepy Mini Portfolio

I’m thinking of doing a 4 way equal split between Canadian equity, U.S. equity, International equity, and Canadian bond using TD’s e-series funds and regular monthly contributions. The only thing I have yet to decide is how much to dedicate to this, and whether to do it within a registered account or not. TFSA? RRSP?
