The short version
Simplify High Yield ETF (CDX) seeks returns from junk bonds, which are lower-rated corporate bonds. It mostly does this through swaps on high-yield bond ETFs instead of owning the bonds. A swap is a contract that passes along another asset's return. CDX adds an actively managed credit hedge and an option-writing strategy. The fund pays monthly, with a trailing yield of 8.93% as of October 27, 2026, and charges 0.50% a year.

How it works
CDX is actively managed. Its goal is to maximize total return. It does not track an index. It must keep at least 80% of net assets in investments that give exposure to junk bonds. Junk bonds are those rated below BBB- by S&P or below Baa3 by Moody's. Most of that exposure comes from total return swaps on high-yield bond ETFs. The fund also buys call options and sells put options on those ETFs. Simplify picks the ETFs based on price, liquidity and track record. As of June 30, 2026, the swaps referenced the iShares iBoxx $ High Yield Corporate Bond ETF (HYG). The swap counterparties were Nomura, Morgan Stanley and Citibank.
A swap only requires collateral, so most of the money sits in near-cash holdings. As of June 30, 2026, 49.8% was in Simplify Government Money Market ETF (SBIL) and 24.8% in Simplify Short Term Treasury Futures Strategy ETF (TUA). About 25.5% was in Treasury bills averaging 0.3 years to maturity.
Up to 20% of the portfolio can go into extra derivatives with two jobs. The first is a credit hedge: swaps meant to gain when bonds, or sometimes stocks, fall. The second is income from writing options and option spreads on stocks, debt, volatility indexes, commodities and currencies. These positions are reset monthly, quarterly or yearly, or more often when markets swing. Derivatives can magnify losses, and the hedge will not fully protect the fund.
What it really costs
- CDX charges 0.5% a year, versus an average of 0.86% for the similar funds below (1st of 8, cheapest first).
- Of that, 0.38% is the management fee; the rest covers other fund expenses.
- Using the prospectus's standard example, $10,000 invested would cost about $51 in the first year and $628 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| CDX | $51 | $160 | $280 | $628 |
Structure and tax notes
- Generates much of its income from selling options (directly or through notes). That income is usually taxed as ordinary income rather than as qualified dividends, and the strategy gives up some upside in strong markets.
- Invests in other funds rather than directly in stocks or bonds, so its holdings are those funds.
- Bond prices move opposite to interest rates; the longer the maturities it holds, the more its price reacts to rate changes.
In a retirement portfolio
Its main draw is monthly income from junk bond exposure and option premiums, though its swaps and option overlay make it more complex than a plain bond fund.
CDX launched in February 2022. It has no record through the 2008 or 2020 crashes, and it missed the start of the 2022 bear market. Its deepest drop was 11.8%, from March 29 to October 20, 2022. It had recovered by November 3, 2023. Every full calendar year so far has been positive, and 2024 was the weakest at 8.62%. But the fund was down 2.9% for 2026 through October 27. A retiree who sells shares in a year like that locks in losses. The trailing yield was 8.93% as of October 27, 2026, paid monthly. Much of that income is usually taxed as ordinary income. The 0.50% expense ratio comes to $51 in year one and $628 over 10 years on $10,000, using the SEC's standard example. Past results don't predict future returns, and a retirement plan should look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Income seekers who want monthly payouts (8.93% trailing yield as of October 27, 2026) and can accept the default risk of junk bonds.
- Investors who want junk bond exposure with an active credit hedge that may soften some losses, at a 0.50% expense ratio.
- Holders using tax-advantaged accounts, where distributions taxed as ordinary income from bond exposure and option premiums matter less.
Look elsewhere if
- Investors who want to own bonds directly; CDX holds mostly money market and Treasury funds and relies on swaps that carry counterparty risk.
- Anyone wanting a simple, transparent fund; option writing on commodities, currencies and volatility indexes adds risks beyond junk bonds.
- Those wanting a long track record; launched in February 2022, CDX has no history through the 2008 or 2020 crashes.

Questions investors ask
Does CDX pay monthly dividends?
Yes. CDX pays distributions monthly. Over the 12 months to October 27, 2026, it paid $1.81 per share, a trailing yield of 8.93%. The money comes from junk bond exposure, held mostly through swaps, plus premiums from selling options. Option income is usually taxed as ordinary income, not as lower-taxed qualified dividends. Payouts can change from month to month, and a high yield does not mean the share price will hold steady.
How does CDX invest in junk bonds without owning them?
It mainly uses total return swaps. These are contracts in which a bank pays the fund the return of a high-yield bond ETF. As of June 30, 2026, the swaps referenced the iShares iBoxx $ High Yield Corporate Bond ETF (HYG), with Nomura, Morgan Stanley and Citibank on the other side. The fund's cash sat in Simplify's money market and Treasury ETFs and in Treasury bills. If a counterparty failed to pay, the fund could lose money.
How has CDX performed compared with the high yield bond index?
It has stayed close to the index. In 2025, CDX returned 8.67%, while the ICE BofA US High Yield Index returned 8.5%. From launch through December 31, 2025, the fund averaged 5.32% a year against 5.67% for the index. The index has no fees. Results have been weaker since then. Based on price, the fund lost 3.8% over the year to October 27, 2026, and 2.9% for 2026 through that date.
Is CDX a buffer ETF like BUFR?
No. The fund-matching screen grouped CDX with buffer funds such as FT Vest Laddered Buffer ETF (BUFR), which charges 0.95%. Buffer funds use options to limit stock market losses within set ranges. CDX is a high-yield bond fund, so these funds are not close alternatives. CDX's 0.50% fee is lower than the 0.79% to 0.95% those funds charge, but the strategies differ too much for the comparison to be like-for-like.
Is CDX a risky investment?
It carries more risk than a high-quality bond fund. Junk bonds default more often, and they tend to fall in downturns. Swaps and options bring counterparty and leverage risk, and the prospectus says the hedge will not fully protect the fund. The deepest drop so far was 11.8%, in 2022. Three-year volatility was 10.7% as of October 27, 2026. Net assets were $393.5 million as of June 30, 2026, after $59.2 million of outflows over the prior three months.
