I've been following an older Canadian Couch Potato portfolio for a few years now. The market has been mostly growing since 2010 so it probably doesn't count, but it's been returning an average of 7-8% every year (dividend+gain). Even last year, when the Canadian economy didn't do well, its return was positive.

It takes more than 4-5 hours a year for me though. I invest a part of my income every month. It makes sense since I don't pay any commission on purchases, so YMMV.
