BUCK vs FIAX

BUCKASimplify Treasury Option Income ETF

FIAXDNicholas Fixed Income Alternative ETF

In short

BUCK Most Treasury option-income funds write calls on 20+ year bonds and hand you the duration ride. BUCK works the short end: U.S. government securities kept to a year or less of duration, with an option overlay on top, paying monthly.

FIAX Most options-income funds write calls on stocks. FIAX holds short-term U.S. Treasuries and runs a defined-risk options overlay on ETFs and indexes for the income, then measures itself against the Agg. A bond-shaped wrapper around an options engine.

Stated mandate

BUCK The fund seeks monthly income through an actively managed portfolio with at least 80% of net assets in U.S. government securities. It seeks total returns while keeping duration at one year or less and uses risk-managed option writing to add income and total return.

FIAX The Fund seeks current income through short-term U.S. Treasury fixed income securities combined with a defined-risk option premium strategy using options on ETFs and securities indices.

Why people hold it

• BUCK Duration is capped at one year or less by mandate, so income leans on the option writing rather than a bet on long-bond prices.simplify.us
• A 0.35% expense ratio undercuts the typical fee among Treasury option-income funds and ties the cheapest of its top-ranked peers, TLTW.
• Pays monthly, with at least 80% of net assets in U.S. government securities, so the engine sits on Treasuries rather than corporate credit.
• Sits in the upper half of its small Treasury-overlay peer group, one of the stronger takes on the short-bonds-plus-options idea.

• FIAX The income engine is options, not coupons: short-term Treasury holdings paired with a defined-risk option premium strategy on ETFs and securities indexes.
• The Treasury sleeve is short-term, so interest-rate sensitivity sits far below the Bloomberg US Aggregate Bond Index it benchmarks against.
• Distributions are paid monthly, and the fund has been running live since its 2022 launch.

Worth knowing

• BUCK Actively managed with no published index behind it. Results ride on how the manager runs the option book, and premium income varies month to month.
• Selling options is a trade: premium now in exchange for giving up some upside on the underlying positions.simplify.us
• Launched in 2022, so the live record covers a short and unusual stretch of rate history.

• FIAX The 0.97% expense ratio sits at the pricier end of the options-income group, where index-overlay peers like LQDW charge 0.34%.
• It trades thinly, so bid-ask spreads are typically wider than the heavily traded names in its category and order execution carries more weight.
• The options overlay is actively managed rather than a mechanical index formula, so outcomes depend on the manager's positioning, not a published rulebook.
