How iShares Core Universal USD Bond ETF (IUSB) compares with the whole market and its popular alternatives

It places IUSB (iShares Core Universal USD Bond ETF) against 20+ popular alternatives, its neighboring categories and the entire market of over 10,000 U.S.-listed stocks and ETFs, and surfaces what has done better on consistent outperformance, return for the risk taken, behavior in real market crashes and diversification.

Period covered: IUSB's full trading record, from June 2014 through September 2026. The crash tests reach back to 2000 using older funds and the S&P 500. All returns include reinvested dividends. Data as of October 20, 2026.

Key findings

How much would $10,000 in IUSB have grown?

This chart tracks a hypothetical $10,000 investment in IUSB over the past 12 years, with dividends reinvested, alongside the same amount in the S&P 500, investments that ended ahead of IUSB over the same span and IUSB's popular alternatives, among those that traded for the entire period. A second view covers the past 5 years, the period the better options further down the page are judged on. It shows not only where each investment ended up but also how smooth or uneven the path was.

Note: IUSB began trading on June 12, 2014, so the chart cannot reach back to the dot-com bust, the 2008 financial crisis or two other sell-offs. It covers the most recent 12 years of IUSB's record, starting at the end of September 2014.

How does IUSB rank among all ETFs?

This section ranks IUSB on return, volatility, risk-adjusted return and worst decline against every ETF worth at least $100 million with enough history. Where the comparisons with its popular alternatives show how IUSB stacks up against its peers, these rankings show where it stands in the market as a whole.

Ranked against U.S.-listed ETFs with at least $100M in assets that have enough history for each measure, so the count changes from row to row; smaller ETFs and leveraged funds are left out. Lower volatility and smaller declines rank higher.

What has beaten IUSB on both return and risk?

Each dot is an investment, placed by how much it earned a year over the past 5 years (higher is better) and how much its price swung, its volatility (further left is calmer). IUSB sits where the dashed lines cross. Anything in the green box above and to the left earned more than IUSB with smaller swings, a better trade-off over this period on both counts. Past results are no promise, but a name in the box is worth a closer look.

Annual return is the annualized total return with dividends reinvested, and volatility the annualized swing in daily prices, both over 5 years. Labeled dots are the strongest picks from the table below and the names called out above, colored by how close they sit to IUSB; faint dots are 22 more of the 82 in the green region (the strongest, one per fund family). 3,633 stocks and funds worth at least $500 million were screened.

Is there a better investment than IUSB?

Investments that beat IUSB over the past 5 years on return, volatility, drawdowns, consistency, crash losses or fees, from its popular alternatives out to the whole market.

How this works

The table below lists investments that beat IUSB over the past 5 years on at least one of these measures: a higher annual return with lower volatility, a higher annual return at similar volatility, a similar return with lower volatility, a higher Sharpe ratio with a smaller worst decline, a higher total return in most periods from 3 months to 10 years, or smaller losses in recent market crashes, and, for funds, the same exposure at a lower expense ratio. It checks IUSB's popular alternatives first, then the rest of its own and neighboring categories, then every stock and fund worth at least $500 million, and shows the strongest few in each group. The full list of those with a higher return and lower volatility than IUSB follows the table.

Annual return is the annualized total return with dividends reinvested. Annual return, volatility and the Sharpe ratio cover 5 years; the worst decline covers the past 10 years. Green marks a better figure than IUSB's. "On the frontier" means no other option shown or tested earned more with less volatility. Funds that hold the same thing are shown once. Beyond the popular alternatives, nothing with more than 1.5× IUSB's volatility counts as better.

These figures cover the past 5 years. Green marks a better figure than IUSB's.

What these numbers mean for IUSB
Annual return
IUSB returned 0.0% a year over the past 5 years with dividends reinvested, against 12.7% a year for the S&P 500. At that pace, $10,000 became about $10,000. Annual return is the steady yearly rate that would produce the same total result, so investments held over the same span compare fairly. Guide: What is performance and return? →
Volatility
IUSB's volatility over the past 5 years was 5.9%, 34% of the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, IUSB's return lands within 5.9% of its average, either way. The higher it is, the rougher the ride and the harder it is to hold through a slump. Guide: Understanding and measuring risk (volatility) →
Sharpe ratio
IUSB's Sharpe ratio over the past 5 years was 0.04, against 0.79 for the S&P 500, so IUSB earned less for each unit of risk than an index fund did. The Sharpe ratio is the return earned above cash for each unit of volatility: two investments with the same return are not equal if one got there with far bigger swings. Guide: Balancing reward with risk (Sharpe ratio) →
Worst decline
IUSB's worst fall from a peak to a low over the past 10 years was 17.9%, against 33.7% for the S&P 500. Losses and gains are not symmetric: climbing back from a 17.9% fall takes a 21.8% gain. Guide: Market crash risk and tail risk →
Correlation
Over the past 5 years, IUSB's monthly returns had a correlation of 0.64 with the S&P 500. Correlation runs from 1 (moving in lockstep) through 0 (unrelated) to −1 (moving in opposite directions). They often move together: some diversification next to an index fund, but not a cushion. In the table, the correlation column measures each option against IUSB instead: the lower it is, the more that option would diversify a IUSB holding. Guide: Correlation and diversification →

How did IUSB do year by year?

This table shows each investment's total return in every full calendar year since 2015, along with where IUSB ranked among its popular alternatives each year. Annual results reveal how consistently each one kept pace with IUSB and how far its good and bad years diverged, detail that multiyear averages tend to smooth over.

Note: IUSB began trading on June 12, 2014, so the table starts with 2015, its first full calendar year, and cannot show how it fared during the dot-com bust, the 2008 financial crisis or two other sell-offs.

Newest year first. Green marks a year in which the fund came out ahead of IUSB; gray means the two finished within a fraction of a point. The rank row places IUSB among the alternatives that traded the full year; dark green is the top quarter and red the bottom quarter.

Risk and diversification

How IUSB has fallen, how it held up in crashes beside the S&P 500 and its popular alternatives, and what moves independently of it.

What were IUSB's worst declines?

A drawdown is the decline from a peak to the lowest point before a new high. This section presents IUSB's two deepest drawdowns since it began trading in 2014, alongside the S&P 500's return over the same dates, and how long each took to recover. Together, these figures show how much an investor could have lost and how long it took to get back to even.

Note: IUSB began trading on June 12, 2014, so this list cannot include the dot-com bust, the 2008 financial crisis or two other sell-offs. The crash tests on this page show how older funds and the S&P 500 fared through those years.

Green means IUSB fell less than the S&P 500 over the same dates. Based on daily closing prices with dividends reinvested.

How did IUSB do in stock market crashes?

This section measures how far IUSB, the S&P 500 and each alternative fell from peak to trough during every major market crash since 2000. A smaller decline means an investment held up better, and comparing results across crashes shows whether that resilience was consistent or a one-off.

Note: IUSB began trading on June 12, 2014, so its row reads "Not yet trading" for the dot-com bust, the 2008 financial crisis or two other sell-offs. The older alternatives and the S&P 500 show how those crashes played out.

Newest crash first. Each figure is the fund's deepest fall within the crash window; green means a smaller fall than IUSB.

How closely does IUSB move with the S&P 500?

Upside capture measures how much of the S&P 500's gains an investment kept in the months the market rose, and downside capture how much of its losses it took in the months the market fell. An investment that captures more of the gains than the losses has compounded ahead of the market over time. This section compares IUSB with its popular alternatives on both measures, and on beta (how strongly each has moved with the market), over the past 10 years.

Monthly total returns over the past 10 years, measured against SPY. 100% capture or a beta of 1.00 means moving in line with the S&P 500. Green marks a better figure than IUSB's: more upside, less downside or a higher capture ratio. Sorted by capture ratio.

What diversifies IUSB?

Correlation measures how closely two investments move together, on a scale from 1 (in lockstep) through 0 (unrelated) to -1 (in opposite directions). This section lists large ETFs and stocks whose returns have had a low correlation with IUSB's. Because such investments tend not to fall at the same time, pairing IUSB with them can reduce a portfolio's overall swings.

Only ETFs with at least $1.0B in assets and stocks worth at least $10B, with a correlation below 0.5 over the past 5 years and a positive return, are included, ranked by Sharpe ratio; funds that hold the same thing are shown once. The year columns are the years in which IUSB lost money. The last two columns show a portfolio that is 80% IUSB and 20% the other investment, rebalanced monthly.

Common questions

What was IUSB's worst drawdown?

IUSB's deepest decline since it began trading in 2014 was 17.9%, from December 2020 to October 2022. It took about three years from the low to climb back to its old high. Because IUSB launched in June 2014, that record does not include the dot-com bust, the 2008 financial crisis or two other sell-offs.

What were IUSB's best and worst years?

Over 11 full calendar years, IUSB's best year was 2019, when it returned 9.1%. Its worst was 2022, with a return of -13.0%.

Is there a better investment than IUSB?

Among IUSB's popular alternatives, HYG was ahead of IUSB in most short and long periods, though with much bigger swings (7.5% volatility against 5.9%). VCIT tracks the same thing for 0.03% a year against IUSB's 0.06%, and has kept pace over the past decade: about $30 less in fees on $10,000 over 10 years.

Is IUSB more volatile than the S&P 500?

No. IUSB's volatility over the past 5 years was 5.9%, 34% of the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, IUSB's return lands within 5.9% of its average, either way. The higher it is, the rougher the ride and the harder it is to hold through a slump.

What is IUSB's Sharpe ratio?

IUSB's Sharpe ratio over the past 5 years was 0.04, against 0.79 for the S&P 500, so IUSB earned less for each unit of risk than an index fund did. The Sharpe ratio is the return earned above cash for each unit of volatility: two investments with the same return are not equal if one got there with far bigger swings.

How correlated is IUSB with the S&P 500?

Over the past 5 years, IUSB's monthly returns had a correlation of 0.64 with the S&P 500. Correlation runs from 1 (moving in lockstep) through 0 (unrelated) to −1 (moving in opposite directions). They often move together: some diversification next to an index fund, but not a cushion. In the table, the correlation column measures each option against IUSB instead: the lower it is, the more that option would diversify a IUSB holding.

What are the best alternatives to IUSB?

Of the 25 popular alternatives we compared, two outperformed IUSB in at least 3 of 5 short-term and 2 of 3 long-term timeframes, with dividends reinvested: JNK and HYG.

Did IUSB outperform the S&P 500?

IUSB finished ahead of the S&P 500 (SPY) in two of 11 full calendar years. In 2025, it returned +7.4%, against +17.7% for the index.

How did IUSB do in stock market crashes?

IUSB fell less than the S&P 500 (SPY) in six of the six major crashes it has traded through, and further in no. The clearest case was the Covid crash, when IUSB fell 9.9% and the S&P 500 fell 33.7%.

What diversifies IUSB?

These had a low correlation with IUSB over the past 5 years and still earned a positive 5-year return: among large ETFs, DXJ (correlation 0.27), EMLP (correlation 0.49) and GLD (correlation 0.40); among large stocks, CAH (correlation 0.25), CLS (correlation 0.12) and FIX (correlation 0.19). A correlation near zero means the two have moved largely independently.
