Stock price when the opinion was issued
Do you recommend ZWS as a hedged covered call or prefer something else, and would you hold it at the only US equity in a portfolio? To answer the latter, no. And he prefers SPY-N as your core holding; it pays you yield and cash flow, becuase it holds high-dividend stocks and sells covered calls against them. Also, US dividends are taxed in Canada and don't benefit from the dividend tax credit.
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).
