If one is looking for international diversification, it's a tough exercise. The decisions involve active management vs indexing, global vs regional, value vs growth, emerging vs developed, etc.
A yield based approach offers a simpler approach. By buying ADR's (American Depository Receipts), one can invest in international companies that have the same profile as US and Canadian dividend growth stocks. International companies that have ADR's tend to be followed by US brokers which means that data is available. One of the best sources to begin with is the Bank of New York where you can search by country, industry, and region. Also useful are JPMorgan's ADR.com , Citigroup , Site-By-Site , CIA World Factbook where you can get macro information on every government, country, and territory in the world.
You can screen for ADR's that grow their dividend at Reuters (free but a membership is required) using the following criteria:
{ADR}=T
(This will select only ADRs)
{Sales5YCGr%}<>5000 (This will allow you to see sales growth but not
exclude any stocks)
{EPS5YCGr%}>=15 (This will give you stocks which have grown their earnings
at 15% annually for 5 years)
{Div3YCGr%}>=15 (This will give you stocks which have grown their dividend
at 15% annually for 5 years)
{DbtLT2EqQ}<>5 (This will allow you to see the debt/equity ratio but
not exclude any stocks)
{Yield}<>15 (This will allow you to see the yield but not exclude any
stocks)
{PayRatioTTM}<>200 (This will allow you to see the payout ratio but
not exclude any stocks)
This should produce somewhere around 40 stocks for further analysis.
Additional sources include the S&P Europe 350 Dividend Aristocrats, stocks that have increased their dividends annually for at least 10 years and the ADR Dividend Achievers Index, stocks that have increased their regular annual dividend payment for the last five or more consecutive years.
