I'm a Canadian in my early 30s and I have 100% of my portfolio invested in equities. I've been doing some reading and most sources say that a percentage of your portfolio should be in bonds. I was thinking about redistributing about 20% of my portfolio into a bond index ETF, but I've never been familiar with bonds until now. I'm having trouble figuring out which bond index ETFs are better than others. I've been looking at XBB iShares Universe Bond Index Fund and VSB Canadian Short-Term Bond Index ETF as potential choices. I was wondering if anyone had any thoughts on either of these or if you might suggest a different bond index fund? thanks
