The worst offenders are CDZ.to (Claymore Canadian Dividend), FDL (First Trust Morningstar Dividend Leaders, the top 100 stocks based on dividend yield of the securities listed on NYSE, NYSE Alternext US or NASDAQ, selected byMorningstar), and DTN (WisdomTree Dividend ex-Financials Fund, i.e, without financials!)
For long term investors (as in 'months'), the closest to oversold is GULF (WisdomTree Middle East Dividend Fund, a fundamentally weighted index that measures the performance of companies in the Middle East region).
