Canadian stock-pickers will not want to miss the most thorough and
forward-looking I500 yet

TORONTO, May 10 /CNW/ - The numbers have been crunched and they confirm
the past year was tough on the markets. In Canadian Business magazine's annual
ranking of Canada's 500 largest publicly traded companies (by market
capitalization), only 338 stocks, or 67.6.%, showed a positive return for the
12-month period ending April 13. Last year, 86% accomplished that feat. Stocks
with double-digit gains or better numbered 271, compared to 386 the previous
year. Most noticeable? The average annual gain in this year's Investor 500 was
just 33.9%. Last year? 90.5%.Top 3 Large-Cap Companies by 1-Year Return:

Not only does Canadian Business magazine look back at the previous years'
best performers, it also provides forward-looking picks, based on screens for
different criteria suited to various investing styles, from value and growth
to income and safety. And this year, to emphasize that the I500 is more about
ideas, not recommendations, Canadian Business has expanded its offering
further, by going in-depth on some of the companies that provide the ranking's
highlights (and lowlights), and offering macro takes on sectors and trends,
from oil and gas to global currency instability.
Canadian Business also ranks the top 50 companies by revenue, profit,
market cap and one- and five-year return. Also, Canadian Business' writers go
beyond the Canadian stocks to highlight some strong performers in overseas
markets.

How we did it:

The rankings were compiled by staff writer Calvin Leung and data manager
Phil Froats using Bloomberg. See the issue on newsstands for a detailed
explanation of methodology.
