The YieldMax Innovation Option Income Strategy ETF, or OARK, functions as an actively managed exchange-traded fund. Its core objective is to deliver regular weekly income to its holders. This income is primarily derived from the sale of call options or call spreads written against the ARKK exchange-traded fund. The overall methodology is constructed to gather income from these option premiums, concurrently offering some exposure to any upward movement in ARKK's underlying share price.
