There are many flavours of income generating ETFs using a various combination of options, structured product strategies, high yielding stocks, and volatility control.

This is a rapidly growing sector as demand for income from investors remains high. In a market of rising interesting rates again (5% in many markets), investors are often very yield hungry. The higher levels of risk-free rates means that more ambitious income levels (in the 8%-12% range) can be achieved with moderate risk that would not be possible if rates were near zero.

In this article, we explore equity premium income strategies, commonly known as buy-write or covered call ETFs. These strategies generate regular income by selling call options against an index or stock portfolio, trading some potential upside for an income stream that is typically distributed monthly.

A typical fund in this sector will hold an index or stocks and sell call options against some or all that position. In falling or sideways markets the premiums act as a buffer with the sweet spot being near flat markets where income is banked but the loss of upside is not significant. In strong market rallies, this strategy may underperform the broader markets because gains are capped once the option’s strike price is reached.

Some leading examples are:

The core strategy types are:

Full overwrite

Every month, the fund sells calls against nearly the entire portfolio, near-the-money. This maximises monthly premium income and gives the highest headline yield, but it also caps upside almost completely. In a strong bull run, a full-overwrite fund can badly lag the underlying it is based on. Examples include: QYLD, XYLD, QYLE, XYLU, SYLD and DYLD.

Partial and Partial / active overwrite

These write calls on only a portion of the portfolio and typically choose strikes further out of the money. They have lower headline yields than full-overwriting funds, but historically better at capturing a decent meaningful portion upside in rising markets while still cushioning drawdowns. Examples include: JPMorgan's whole Equity Premium Income range (JEPI/JEPQ/JEPG-style), DIVO, Invesco QQIA, REX's FEGI.

Overwriting can be rules based or more actively determined.

Target-income

These rules based strategies aim for a fixed target and dynamically size the option overlay to chase a specific stated income target (e.g. "8% annual") rather than writing calls on a fixed percentage of the portfolio every time. It's a more mechanical, index-tracked approach: cheaper to run, more transparent, but less adaptive to changing volatility regimes than some actively managed versions. Examples include: Amundi's Target Income pair (MSET, NSDT), First Trust's KNG

These strategies behave differently relative to other investments in various market cycles as follows.

Sideways/range-bound markets are where the strategy works best on a relative basis. The underlying does not move much, so premium is collected with minimal upside given away. This tends to beat both a direct index holding and cash.

In bear markets or large drawdowns, the premiums provide a real (if modest) cushion. Historically, these funds have tended to fall less than the index during down years, as option income partially offsets losses in the underlying portfolio. However, the strategy will generally still produce a negative total return when markets decline.

Strong bull markets are arguably the weak spot, especially for full-overwrite funds. The 2023–2025 tech-led rally is a good example: Nasdaq covered call strategies badly lagged QQQ over that period because upside above the strike was repeatedly capped and sold away. Partial-overwrite funds lagged less but still gave up meaningful relative performance versus just holding the Nasdaq-100 or S&P 500 outright. In strong markets, the funds still perform quite well on an absolute basis but underperform against the index. In such cases it is important for investors to be realistic about the construction of the fund and that the opportunity cost of underperformance is to be expected.

When volatility spikes these funds often benefit at the start of such a regime because option premiums and income increase. However, if the volatility comes with a sharp underlying decline, the fund will lose value.

It is interesting to compare these types of strategies with buffered ETFs. For premium income (covered call) funds, they own the stocks or index and continuously sell call options against them. The trade-off is symmetric and ongoing: every period you give up some upside, in exchange for cash income every period. There is no protection against losses beyond what premium was collected for that month. For example, if the market drops 20%, you still lose 20% minus whatever was collected as premium.

For buffered (defined outcome) ETFs, the fund uses a package of index options to engineer a defined result over a fixed "outcome period" (usually 1 year, sometimes quarterly): a buffer against the first portion of losses in exchange for a cap on how much upside you can capture. Generally, the buffer is set fixed, and the cap resets each outcome period based on prevailing option pricing. The premium income ETF family represent an interesting alternative solution to producing stable income with controlled downside risks.
