    "text_markdown": "By Adam Patti, Chief Executive Officer, VistaShares | November 2026\n\nSome investors weigh buffer ETFs against bond ETFs when deciding how to temper the swings of a stock portfolio. The two categories work very differently: a buffer fund stays tied to the stock market with a defined range of outcomes, while a bond fund holds debt and moves with interest rates. This page sets the two side by side with dated figures on fund counts, assets, fees and recent flows.\n\nFigure | Buffer ETFs | Bond ETFs |\n\nFunds tracked by ETFIQ (Nov 12, 2026) | 524 | 853 |\n\nShare of the 5,146 ETFs ETFIQ covers (Nov 12, 2026) | 10% | 17% |\n\nCombined net assets (Nov 12, 2026) | $75.3 billion, the 431 single-period funds | $2.7 trillion, all 853 funds |\n\nMedian yearly fee, per prospectus (Nov 12, 2026) | 0.79%, the 431 single-period funds | 0.25% |\n\nLargest single fund, net assets | $11.1 billion, a laddered fund (Nov 11, 2026) | $167.4 billion (Oct 31, 2026) |\n\nNet flows, month to Nov 11, 2026 | $1.1 billion in, 268 of 523 funds counted | $27.2 billion in, 344 of 852 funds counted |\n\nNet flows, week to Nov 11, 2026 | $249 million in, 314 of 523 funds counted | $5.7 billion in, 342 of 852 funds counted |\n\nAverage fee, outside measures (2025) | 0.75% for defined outcome ETFs (Morningstar, Dec 31, 2025) | 0.09% for index bond ETFs, asset-weighted (ICI) |\n\nSources: counts and shares, [ETFIQ ETF statistics](https://etfiq.com/statistics/), data as of Nov 12, 2026; buffer assets and fee, [ETFIQ buffer ETFs](https://etfiq.com/buffer/), as of Nov 12, 2026; largest buffer fund, [ETFIQ laddered buffer ETFs](https://etfiq.com/buffer/laddered), as of Nov 11, 2026; bond assets, fee and largest fund, [ETFIQ bond ETFs](https://etfiq.com/bonds/), as of Nov 12, 2026; flows, [ETFIQ fund flows](https://etfiq.com/flows/), as of Nov 11, 2026; outside measures, Morningstar and ICI (notes 1 and 2). Flows count only funds with daily share data.\n\n## Why compare buffer ETFs with bond ETFs?\n\nBonds have long been the standard way to reduce the ups and downs of a stock portfolio. Buffer ETFs offer another approach: they keep stock market exposure but use options that seek to absorb a stated slice of losses over an outcome period, in exchange for a cap on gains. Because both are used to temper risk, investors sometimes weigh one against the other.\n\nThey are not substitutes. A bond fund's value moves with interest rates and credit conditions, and it pays interest. A buffer fund's value moves with a stock index, within its buffer and cap, and most buffer funds pay little or nothing in distributions. Our comparison of [buffer ETFs vs. bonds](https://www.vistashares.com/buffer-etfs-vs-bonds/) explains the trade-offs, and [how buffer ETFs work](https://www.vistashares.com/how-do-buffer-etfs-work/) covers the mechanics.\n\n## How large is each category?\n\nETFIQ tracked [524 buffer ETFs and 853 bond ETFs](https://etfiq.com/statistics/) as of November 12, 2026, or 10% and 17% of the 5,146 ETFs it covers. By assets the gap is far wider. Bond ETFs held a combined [$2.7 trillion](https://etfiq.com/bonds/), while the 431 buffer funds on a single outcome period held [$75.3 billion](https://etfiq.com/buffer/). Morningstar's Defined Outcome category held $78 billion across 420 ETFs at the end of 2025.[1]\n\nThe largest bond ETF held $167.4 billion as of October 31, 2026. The largest buffer ETF, a laddered fund that holds a series of buffer funds with different start months, held [$11.1 billion](https://etfiq.com/buffer/laddered) as of November 11, 2026. Buffer ETFs are also a young category: the first outcome-based ETFs launched in 2018, according to Cboe.[3]\n\n## How do fees compare?\n\nThe median bond ETF charged [0.25% a year](https://etfiq.com/bonds/) as of November 12, 2026, against [0.79%](https://etfiq.com/buffer/) for the median single-period buffer ETF. Asset-weighted, the difference is larger: ICI put the average for index bond ETFs at 0.09% in 2025, and Morningstar put the average for defined outcome ETFs at 0.75% at the end of 2025.[2]\n\nA buffer fund pays for an options package that is struck and reset each outcome period, and most are actively managed. A broad bond index fund mainly tracks a list of bonds. Buffer fees still vary from fund to fund, and our guide on [how to choose a buffer ETF](https://www.vistashares.com/how-to-choose-a-buffer-etf/) lists what else to compare.\n\n## Where has money been flowing?\n\nIn the month to November 11, 2026, bond ETFs with daily data took in a net [$27.2 billion](https://etfiq.com/flows/) across 344 funds, and buffer ETFs took in $1.1 billion across 268 funds. In the week to the same date, bond ETFs took in $5.7 billion and buffer ETFs $249 million.\n\nThese are estimates from each fund's daily change in shares outstanding multiplied by the prior day's net asset value, for funds that publish daily share data. The flows page counted 523 buffer funds and 852 bond funds, one fewer in each than the statistics page, so the two fund sets differ slightly.\n\n## How do they behave differently?\n\n**Link to stocks:** a buffer fund rises and falls with its stock index, within its buffer and cap. A bond fund's link to stocks varies over time and can be weak or even positive in some markets.\n\n**Time frame:** a buffer fund's defined outcome applies over a full outcome period, usually a year, for an investor who holds from start to end. A bond fund has no such period, although target maturity bond funds close on a set date.\n\n**Income:** bond funds pay interest, usually monthly. Most buffer funds are built for price exposure rather than income. Our article on [100% buffer ETFs](https://www.vistashares.com/what-are-100-percent-buffer-etfs/) covers funds that seek to absorb all of an index's losses over a period. More buffer articles are in the [Buffer ETF Guide](https://www.vistashares.com/buffer-etf-guide/).\n\n## Frequently asked questions\n\n### Are there more buffer ETFs or bond ETFs?\n\nBond ETFs.
