The BMO Covered Call Canadian Banks ETF seeks to provide exposure to a portfolio of Canadian banks while earning call option premiums. The ETF invests in equity securities of Canadian banks and dynamically writes covered call options. The option premiums provide some downside protection. The ETF may hold other underlying ETFs, the management fees charged are reduced by the management fees paid on the underlying ETFs, thereby not duplicating the management fees. ZWB.T pays a 13% annual distribution set yearly and paid monthly.
