Stock price when the opinion was issued
Main thing is it's not leveraged. Holds all the big, household names. Dividends are small on US stocks, so most of the premium you're getting is from the covered calls which are capital gains. Hasn't come back from April because it doesn't have all the super-charged tech stocks. Yield is around 6-6.5%.
At market bottoms you don’t want ETFs with covered calls like ZWH-T because you are giving away some of the upside. You want ZDY-T or the currency hedged version of that. CYH-T is a benchmark for world dividends. It is a Canadian dollar currency hedged ETF. TDIV-Q is a technology dividend play.
