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%.
BMO has the biggest suite of covered call strategies around the world. For US high-dividend covered-call strategies, ZWS or ZWH are really good (one hedged, one not).
