IVVW vs MRSK

IVVWAiShares S&P 500 BuyWrite ETF

MRSKFToews Agility Shares Managed Risk ETF

In short

IVVW BlackRock's version of the covered call: hold the whole S&P 500 through the iShares Core fund, sell one-month index calls struck 1% out of the money, pay the premium out monthly. All for a quarter-point fee.

MRSK Most options-income funds just sell calls on stocks. MRSK runs two engines: S&P 500 exposure plus options on one side, Treasuries and Treasury futures on the other, chasing income and growth while trying to limit the damage.

Stated mandate

IVVW The fund seeks to track an index strategy that holds the iShares Core S&P 500 ETF and sells one-month call options primarily on the S&P 500 Index to generate income. The short option position is intended to be offset by the fund’s long position in the underlying ETF.

MRSK The Fund seeks income and long-term capital growth while limiting risk. It combines an equity-market strategy using S&P 500 exposure and options with a fixed-income strategy using U.S. Treasury securities and related futures.

Why people hold it

• IVVW Costs 0.25% a year against a category median near 0.60%. On an income strategy, that is less of the option premium quietly leaking out the door.
• The calls sit 1% out of the money, so a slice of each month's rally still belongs to shareholders before the cap bites. At-the-money writers give that up.cboe.com
• Rules over hunches: it tracks a Cboe index that pairs a long position in the iShares Core S&P 500 ETF with a short monthly S&P 500 call, rolled on a set schedule.cboe.com
• Inside a crowded covered-call field where fat fees are the norm, this is one of the tighter builds in its peer group.

• MRSK Two sleeves, one ticker: an S&P 500 equity-and-options book paired with U.S. Treasuries and Treasury futures, aimed at income and long-term growth while limiting risk.
• Live since 2020, so there's a multi-year record across real market stress to examine, not a backtest.
• Actively run with the S&P 500 as its reference point, so the manager sets the stock, options and bond mix instead of following a fixed overlay rule.

Worth knowing

• IVVW Covered calls trade upside for income. Above the strike, the month's gain is capped, and the premium cushions losses rather than blocking them.cboe.com
• Monthly payouts come from option premium, so they move with volatility instead of arriving as a fixed amount.
• Launched in 2024 and moderately traded, so the live record is short and spreads can run wider than the category's biggest names.

• MRSK At 0.98%, it costs more than the typical fund in its options-income group, and more than same-benchmark peers such as NBOS (0.59%) and SIXH (0.73%).
• Thinly traded next to the category's heavyweights, so spreads can be wider and larger orders need more care at the point of execution.
• Distributions land annually or semiannually rather than monthly, so the cash flow is lumpier than in most income-focused peers.
