Having just completed the Top Picks report for 2007 – the 24th consecutive year I have surveyed the newsletter advisors for their favorite stocks -- I thought I would share some observations to help readers best use the information in this feature.

And over the next few days, I will post articles to share observations on the stocks and sectors chosen, discuss the participating advisors, and highlight some of last year's top performers to help guide you in assessing this year's report.

I'll begin today by noting some caveats that should be kept in mind by those who are considering buying stocks from among the list of Top Picks. The advisors who have participated in this year's project were asked to submit a favorite speculative and/or conservative stock for the year ahead.

Each year Steven Halpern, editor of TheStockAdvisors.com, surveys the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is part of his 24th annual Top Picks Report.

Canadian Oil Sands Trust (TSX: COS.UN) is the top conservative buy for 2007 from international investing expert Vivian Lewis. The editor of Global Investing notes, "Canada recently slapped surprise taxes on income trusts. Nevertheless, we think oil sands will also be a good idea even if not exempt from taxes on dividends.

"The main reason is that the dividends are pretty meager. COS pays 2.7%. This is not going to cause a sell-off in the share, even if the dividend is cut in 2011. The trust, however, dropped 10% in what I consider a mistaken reaction to the tax news.

"Meanwhile, Canadian Oil Sands Trust saw third quarter volumes and sales prices rise, which partly offset higher royalties paid, while net fell 27%. The dividend is 30 cents per unit. The stock is up 41%, including dividends, over the past year.
