Mulvihill Canadian Bank Enhanced Yield ETF (CBNK.TO)

Likes it. Whenever he sees the word "enhanced", he thinks covered calls (and there's nothing wrong with that). But look to see if there's any leverage (he's not a fan because of the risk), as it's often 25%.

Does not expect spread to widen too much. Better names to trade due to liquidity. Would not recommend buying at this time. 

A covered call on banks, which is similar to ZWB. The difference, however, is that Mulvihill uses leverage of 25%. He doesn't buy anything that uses leverage or margins, as there's too much risk to clients who are retired or soon to be. Nothing wrong with it as long as you're willing to accept the risk.
