This actively managed exchange-traded fund, known as the YieldMax MRNA Option Income Strategy ETF (MRNY), is engineered to deliver consistent weekly income. It achieves this by strategically issuing call options or initiating call spreads that are tied to shares of MRNA. The fundamental design of this approach is to collect premiums from these options, while also providing investors with a means to participate in any upward movement in MRNA's stock valuation.
