BUCK vs SGOV: Weighing an Active Treasury Options Strategy Against a Low-Cost Passive Alternative

BUCK vs SGOV: Weighing an Active Treasury Options Strategy Against a Low-Cost Passive Alternative

Key Takeaways

  • Different strategies, similar goal. BUCK is an actively managed enhanced-income fund that pairs short-term Treasuries with an options overlay, while SGOV is a passive, ultra-short Treasury bill index fund.
  • Cost gap is material. SGOV charges a 0.09% expense ratio versus 0.35% for BUCK, a meaningful difference for yield-oriented cash-management allocations.
  • Risk profiles diverge. SGOV carries near-zero interest-rate and credit risk, while BUCK layers on defined-risk options exposure that can introduce equity- and rates-market sensitivity.
  • Income versus predictability. BUCK targets higher monthly distributions through option-premium harvesting, whereas SGOV's yield simply tracks short-term Treasury bill rates.
  • Scale and liquidity favor SGOV. SGOV is among the largest ultra-short Treasury ETFs with deep secondary-market liquidity; BUCK is smaller and newer, having launched in 2022.
  • Tickeron AI Verdict: SGOV is the preferred choice for its lower cost, structural simplicity, and superior liquidity.

Why These Two Funds Matter Right Now

In an environment where investors continue to seek safe, income-producing places to park cash, ultra-short-duration funds have become a central allocation decision. BUCK and SGOV both target short-duration, Treasury-anchored exposure, yet they represent fundamentally different approaches to the same investor goal. SGOV is a plain-vanilla Treasury bill index fund built for capital preservation and liquidity, while BUCK is an actively managed strategy designed to enhance income by selling options on top of a short-term Treasury core. I also checked this using Tickeron’s AI Screener to see how the two line up against peers in the category. Comparing the two clarifies the trade-off between cost, risk, and yield that defines this corner of the fixed-income market.

A Closer Look at BUCK

BUCK is the Simplify Treasury Option Income ETF, formerly known as the Simplify Stable Income ETF. It is an actively managed fund that seeks monthly income through two complementary strategies: an interest-income sleeve invested primarily in short-term U.S. Treasury securities and fixed-income ETFs, and an options overlay that writes short-dated call and put spreads on liquid equity and fixed-income ETFs to harvest option premium. The fund targets a short duration, typically keeping its Treasury exposure around one year or less.

The portfolio is concentrated, holding roughly a dozen positions comprising U.S. Treasury bills, a government money market ETF used as collateral, and a series of Treasury futures options. Because the options overlay references equity-index ETFs, BUCK carries defined-risk market exposure beyond a pure Treasury fund. The fund charges a net expense ratio of 0.35%, distributes income monthly, and has generally offered a distribution yield in the mid-to-high single digits. Launched in October 2022, BUCK is issued by Simplify Asset Management and is an actively managed, non-indexed strategy rather than a passive tracker.

A Closer Look at SGOV

SGOV is the iShares 0-3 Month Treasury Bond ETF, a passively managed fund that tracks the ICE 0-3 Month US Treasury Securities Index. The underlying index holds U.S. Treasury bills with remaining maturities of less than or equal to three months, giving the fund an effective duration of roughly one month or less and essentially zero credit risk, since Treasury securities are backed by the full faith and credit of the U.S. government.

The portfolio holds approximately two dozen individual Treasury bills, with the top five positions representing a meaningful share of assets but all concentrated in short-maturity, zero-coupon U.S. government obligations. SGOV charges an expense ratio of just 0.09%, distributes income monthly, and its yield closely tracks prevailing short-term Treasury bill rates. Issued by BlackRock under the iShares brand and launched in 2020, SGOV is a low-cost, highly liquid vehicle that has become one of the largest ultra-short Treasury ETFs in the market.

The Broader Market Context

Both funds operate within the short-duration Treasury and cash-management segment, which has attracted substantial capital flows as elevated interest rates have made risk-free yields more compelling than in the prior low-rate era. Ultra-short Treasury funds are widely used as alternatives to money market funds, sweep accounts, and bank deposits, offering intraday liquidity and minimal duration risk. Demand has been reinforced by ongoing uncertainty around the path of Federal Reserve policy and by investors seeking to avoid credit and equity-market volatility while still earning income.

The key thematic tension is between yield enhancement and simplicity. Strategies such as BUCK respond to investor demand for higher income by layering options selling onto a Treasury base, accepting modest market-linked risk. In contrast, vehicles such as SGOV prioritize cost efficiency and near-total interest-rate and credit isolation. Regulatory attention to derivative-heavy income products and fee transparency also favors lower-cost, more transparent structures in this segment.

How the Two Have Performed and Positioned Themselves

Over recent market cycles, the relative positioning of these two funds has reflected their structural differences. SGOV has produced a steady, low-volatility total return that tracks short-term Treasury bill yields, with negligible drawdowns and a near-flat price profile because of its ultra-short duration. Its returns have largely mirrored the trajectory of Federal Reserve policy expectations and front-end money-market rates.

BUCK has sought to out-yield a plain Treasury bill allocation by collecting option premiums. This has supported a higher distribution rate in recent months, but the options overlay introduces periodic sensitivity to equity-market moves and realized volatility, meaning its total return can deviate from Treasury bill rates during equity selloffs or spikes in volatility. As a result, BUCK carries more path-dependent return characteristics and slightly higher volatility than SGOV, even though both anchor their portfolios in short-term government securities.

Tickeron AI Verdict

Based on observable structural factors, Tickeron's AI would likely favor SGOV over BUCK in the current environment. SGOV offers a materially lower expense ratio, near-zero duration and credit risk, broad diversification across Treasury bills, deep liquidity, and a consistently stable trend profile. While BUCK may appeal to investors seeking higher distributions, its options overlay introduces additional market sensitivity, higher fees, and greater complexity relative to the incremental yield. On a risk-adjusted, cost-adjusted basis, the probability-weighted outcome favors the simplicity, efficiency, and predictability of SGOV for capital-preservation and cash-management mandates.
