Stock price when the opinion was issued
Yield gets up to about 10% with the covered call overlay. Likes US banks, cheap relative to 5-10 year history. If economy continues to recover, banks should be there. Last 3 months, this has returned 17.5%.
Are you looking for income, or do you just want exposure to US banks? Makes sense if you need the income. He'd argue that you'll get a better total return owning the underlying shares, or an ETF of US banks, instead of using the covered call strategy.
Despite being better diversified, US banking space can be more volatile than Canada's. Because of covered calls, won't achieve as much capital growth as from ZBK or ZUB. As well, consider some of the active options as offered, for example, from Hamilton.
