Measured from Mar 2025 — the start of shared available history — SGOV has compounded at 3.96% a year versus 3.80% for WEEK. SGOV has been the steadier holding, though — annualized volatility of 0.2% against 0.4% for WEEK. Figures are total returns: price change plus every distribution reinvested.

Total return with all distributions reinvested on the ex-dividend date (a modeling convention, not the cash-settlement date), split-adjusted, as of September 21, 2026. YTD and 1Y are cumulative; windows of one year or longer are annualized. “Since Mar 2025” measures every fund from March 6, 2025 — the start of shared available history — so all funds share one comparison window. Volatility is the annualized standard deviation of daily total returns over the past year. Sharpe and Sortino divide the annualized return in excess of the risk-free rate by, respectively, that volatility and the downside deviation (both over the past year) — higher is better. Max drawdown is the largest peak-to-trough total-return decline over the same window — shallower is better.

Bottom lineSGOV and WEEK are both for investors who want fixed-income ballast that steadies the portfolio when stocks fall — so strategy isn't the deciding factor here. Cost is: SGOV charges 0.09% against 0.19% for WEEK, and between two funds this similar that gap comes straight out of your return every year you hold.

WEEK vs SGOV: same bills, different paycheck

Both park cash in 0-3 month US Treasury bills. WEEK pays weekly; SGOV pays monthly. Cost and fund size are the other real gaps — the yield gap is usually just those two plus the payout calendar.

They have different reference exposures: SGOV is linked to ICE 0-3 Month US Treasury Securities Index while WEEK is linked to U.S. Treasury bills (0–3 months), which means their performance drivers differ.

SGOV is the larger fund by assets ($110B), but assets alone do not establish trading costs or liquidity.

Frequently asked questions

What is the 30-day SEC yield for SGOV and WEEK?

SGOV and WEEK have not published a 30-day SEC yield in our data, so we do not quote one — the issuer's own fund page and fact sheet carry the official figure. What we track for every fund is the trailing distribution yield: SGOV at 3.66% and WEEK at 3.53%, based on fund data updated September 2026. The two measures answer different questions. The SEC yield is a standardized 30-day estimate of net investment income after expenses; the distribution yield annualizes what was actually paid out. For short-dated Treasury funds the two usually track each other closely, because nearly all of the return is bill interest paid out as it is earned rather than price movement.

What is the current distribution rate for SGOV and WEEK?

SGOV currently distributes 3.66% and WEEK 3.53%, based on fund data updated September 2026. Distribution rate moves with both the payout and the share price, so check the as-of date before relying on either figure.

Is SGOV or WEEK better for dividend income?

It depends on your goals. SGOV currently offers the higher distribution yield, which means more income per dollar invested. However, a lower-yield fund may offer better total return or lower volatility. Consider your time horizon and risk tolerance.

Can I hold both SGOV and WEEK?

Yes — nothing prevents holding both. Whether the combination actually diversifies depends on how much the underlying exposures overlap, which isn't fully measurable from the data on this page; review each security's holdings, sector, and strategy before treating them as complementary.

Is SGOV or WEEK safer?

By Dividend Vision's Distribution Safety Score — a rules-based 0–100 estimate of how resilient a distribution looks, where higher is safer — WEEK scores 91, SGOV scores 79, so WEEK's payout currently looks the more resilient of the two. No score makes an investment risk-free — treat this as a screening signal, not a guarantee.

Which has lower fees, SGOV or WEEK?

SGOV has an expense ratio of 0.09% while WEEK charges 0.19%. Lower fees mean more of your investment returns stay in your pocket over time.

How much income does $10,000 in SGOV vs WEEK generate?

At current rates, $10,000 in SGOV would generate roughly $30.50 per month ($366.00 annually). The same in WEEK would produce about $29.42 per month ($353.00 annually).

Which has performed better historically, SGOV or WEEK?

SGOV has outpaced WEEK over the trailing twelve months, posting a 3.74% total return against 3.59%. Measured from Mar 2025 — the start of shared available history — SGOV has compounded at 3.96% a year versus 3.80% for WEEK. SGOV has been the steadier holding, though — annualized volatility of 0.2% against 0.4% for WEEK. Figures are total returns: price change plus every distribution reinvested. Past performance does not guarantee future results.

More comparisons to explore

SGOV vs WEEK — at a glance

Generated September 19, 2026.

Overview

Both SGOV and WEEK are Treasury bill ETFs holding U.S. government debt maturing within three months, making them functionally similar cash-management tools. SGOV's 3.66% yield slightly exceeds WEEK's 3.53%, though both offer identical overnight-rate-equivalent pricing. WEEK is new, having opened on 03/06/2025, so it carries limited track record; SGOV has operated since 05/26/2020.

Who each is best for

SGOV: Investors seeking a passive, low-cost Treasury bill allocation with simple monthly reinvestment cadence and the liquidity of a $110 billion fund.

WEEK: Investors who value frequent income recognition or have specific cash-flow timing needs that align with weekly payment schedules, or who are willing to accept a newer, smaller fund for that distribution frequency.

Key risks to know

  • Scale and track record. WEEK's $190M in assets and March 2025 inception date leave it with virtually no operational history; SGOV's $110B and five-year history provide wider evidence of performance consistency. Over a decade, this difference can erode returns by tens of basis points relative to a lower-cost alternative. Frequent micro-distributions do not generate additional returns; the apparent reinvestment benefit exists only if investors immediately redeploy cash into higher-yielding vehicles—a transaction-cost risk itself.

Bottom line

If you prioritize simplicity, low fees, and proven scale, SGOV is the more established choice. If you specifically need weekly income recognition and accept the cost and track-record tradeoff, WEEK delivers that structure. Both offer Treasury bill exposure at comparable yields; the decision turns on distribution timing preference and fee tolerance rather than any fundamental yield or credit advantage.
