Investment Q&A

Q: Hi folks
Two questions.
I have held both these for some time in my wife's LIRA account. She can not access this for about 12 years, so a long term hold is very possible. Have held these for a couple years. Both are down about 10%, I have held on because I see the ETF as a long term play on our aging population, and ACHN (hopefully you have a little info with this) as a risky but likely takeout target down the road. I have trimmed this one down and made a bit of $ in another account with it, so it isn't as bad as it looks.
Looking back, which is always easy, there are better options, however I am in now and wondering if I should stay the course.
Don't mind volatility, actually kind of drawn to it. Any thoughts?
Excellent job btw, your cheap at twice the price!
Cheers ;)

Q: I read with interest your recent article in the Post and was intrigued by the comment that research shows 90% of portfolio returns come from sector allocation - if a person wanted to take advantage of that, in a simple, easy to manage and inexpensive way (ignoring taxes for the moment) what would be your view be on an approach where one's equity component of their portfolio consisted entirely of a number of ETF's with each one of the ETF's focused on a particular sector, with a periodic (say quarterly) rebalancing? What specific ETF's would you suggest for such a portfolio? Thank you.
