Zero-days-to-expiration options — 0DTE for short — have gone from a niche trading tactic to one of the most talked-about corners of the options market in just a few years. These are contracts that expire the same day they’re traded, and their volume has grown more than fivefold since 2022, with over $1 trillion in notional value now changing hands daily. Hamilton ETFs was the first Canadian issuer to build a retail ETF suite around that trend, launching the DayMAX lineup — CDAY, SDAY, and QDAY — in July 2025, with a Bitcoin-linked variant, BDAY, added later.
The pitch is straightforward: instead of writing covered calls once a month like most traditional income ETFs, these funds write them every single trading day, roughly 250 times a year instead of 12. Combine that with a modest 25% leverage overlay, and you get funds currently yielding between 18% and nearly 20%. That’s an attention-grabbing number, and it raises the obvious question this article is built around: is daily options income a genuine structural advantage, or is it simply a faster, more leveraged version of the same trade-offs every covered call fund makes?
What Are the DayMAX ETFs?
The DayMAX suite currently includes four funds, each targeting a different underlying exposure:
- Hamilton Enhanced Canadian Equity DayMAX ETF (CDAY) — invests in the Hamilton Champions Canadian Dividend Index ETF (CMVP), a basket of blue-chip Canadian dividend payers, and writes daily options on the S&P 500 index.
- Hamilton Enhanced U.S. Equity DayMAX ETF (SDAY) — invests in the Hamilton Champions U.S. Dividend Index ETF (SMVP) and writes daily options on the S&P 500.
- Hamilton Enhanced Technology DayMAX ETF (QDAY) — invests in the Hamilton Champions U.S. Technology Index ETF (QMVP) and writes daily options on the Nasdaq 100.
- Hamilton Enhanced Bitcoin DayMAX ETF (BDAY) — a newer addition applying the same structure to Bitcoin exposure.
One detail worth flagging up front: CDAY holds Canadian dividend stocks but writes its options on the S&P 500, not a Canadian index. That’s not an oversight — 0DTE options simply aren’t available yet on Canadian benchmarks, so Hamilton uses U.S. index options to run the strategy while keeping the underlying holdings Canadian. That mismatch between what the fund owns and what it’s writing options against is worth understanding before investing, since it means CDAY’s option income is tied to U.S. market volatility, not the volatility of the Canadian stocks it actually holds.
All four funds pay distributions semi-monthly and are eligible for registered accounts, including the TFSA, RRSP, RRIF, FHSA, and RESP.
Why Daily Options Instead of Monthly?
The core argument behind DayMAX is frequency. A traditional monthly covered call ETF can only sell 12 rounds of options a year. A daily strategy can sell roughly 250. Each individual 0DTE premium tends to be smaller than a one-month premium, but there are far more opportunities to collect one, and the fund also retains full exposure to overnight price moves, since the option written each day expires before the market reopens the next morning.
That overnight-exposure point is central to Hamilton’s pitch: a meaningful share of long-term equity returns has historically occurred outside regular trading hours, and a daily options strategy — unlike a monthly one that locks in a static ceiling for weeks at a time — resets every single day, which in theory lets the fund participate in more of that overnight movement while still collecting premium during the trading session itself.
The Leverage Component
Each DayMAX fund applies roughly 25% leverage, achieved through cash borrowing from a Canadian financial institution rather than derivatives, bringing total equity exposure to about 125% of net asset value. Hamilton frames this as “modest,” and relative to some of the more aggressively leveraged income products on the market, it is.
But leverage is leverage: it amplifies both the income the options strategy generates and the losses that occur when the underlying holdings decline. It’s a meaningful design choice, not a minor technical detail, and investors should treat it as adding a real layer of risk on top of the options strategy itself, not merely a yield booster.
Current Performance and Yields
As of early August 2026, here’s where the three original DayMAX funds stand:
| Fund | Current Yield | NAV | Assets | YTD Return | 1-Year Return | Since Inception (Annualized) |
|---|---|---|---|---|---|---|
| CDAY | 18.24% | $27.65 | $444.9M | 17.4% | 35.7% | 34.8% |
| SDAY | 18.26% | $24.68 | $297.8M | 10.3% | 16.6% | 20.8% |
| QDAY | 19.71% | ~$27.48 | — | — | — | — |
(Figures as of July 31–August 4, 2026, per Hamilton ETFs’ published fund data.)
A few things stand out here. First, these aren’t small funds — CDAY alone has grown to roughly $445 million in assets in about a year, suggesting real investor demand for this structure. Second, the total returns matter as much as the yield. CDAY’s 35.7% one-year total return and SDAY’s 16.6% both reflect a combination of distributions received and NAV movement — and in both cases, the underlying dividend-stock baskets (CMVP and SMVP) have performed well over the period, which has helped support NAV alongside the option income.
That’s an important distinction from a fund where a high yield is being paid out while NAV quietly erodes; based on the numbers available, that doesn’t appear to be the case here so far, though a full market cycle hasn’t been tested yet given the funds’ roughly one-year history.
The Real Risks of a 0DTE Strategy
This is the part of the DayMAX story that gets the least attention in the marketing material, so it’s worth spending real time on it.
0DTE options behave very differently from options with weeks or months until expiration. As an option approaches its final hours, its gamma — how quickly its sensitivity to the underlying price changes — can rise sharply. That means small, sudden moves in the market can have an outsized effect on the option’s value in a short window, and it’s part of why 0DTE trading has drawn scrutiny from regulators and market strategists concerned about concentrated, fast-moving volatility around expiration.
For a fund systematically selling these options every day, that translates into a strategy that is, by design, exposed to sharp intraday swings on a near-daily basis rather than the more spread-out risk profile of a monthly covered call fund. Add the 25% leverage on top, and the combination compounds — both the potential income and the potential downside move faster than in a plain, unlevered monthly strategy.
It’s also worth noting that 0DTE strategies are relatively new territory for retail-facing ETFs generally, in Canada and the U.S. alike. Comparable U.S. products, such as Roundhill’s 0DTE-based Nasdaq covered call fund, have drawn mixed reviews from analysts — generally viewed as a reasonable tool in the right market environment, but not something to hold as a core, permanent equity allocation without understanding the mechanics. The same caution reasonably applies to the DayMAX suite.
None of this means the strategy is broken or that a ~18-20% distribution rate is fake. It means the income is being generated by taking on real, specific risks — daily gamma exposure and leverage — and investors should evaluate DayMAX funds with that trade-off in mind rather than treating the yield in isolation.
DayMAX vs. Traditional Monthly Covered Call ETFs
The clearest way to think about DayMAX is as a different point on the same spectrum as Hamilton’s existing Yield Maximizer monthly covered call funds, not a replacement for them. A monthly strategy writes fewer, larger option positions and tends to produce more predictable, if lower, premium income. A daily strategy writes many small positions, adds leverage, and aims for a higher and more frequent income stream, with more moving parts and more sensitivity to short-term volatility along the way.
Hamilton itself positions DayMAX as a complement to, rather than a substitute for, longer-duration covered call strategies — the idea being that combining both smooths cash flow and diversifies the sources of that income across time horizons. That framing is reasonable: an income investor mixing monthly and daily options-based funds isn’t doubling down on the same risk, but is genuinely blending two different premium-generation approaches.
Who Might Consider DayMAX ETFs
These funds may be a reasonable fit for income-focused investors who already understand covered call and options-income strategies, who are comfortable with the added volatility that leverage introduces, and who see DayMAX as one component of a diversified income approach rather than a standalone core holding. Investors who specifically want blue-chip dividend exposure with an enhanced, more frequent income overlay — and who are willing to accept the trade-offs that come with daily options and leverage — are the more natural audience here.
Who Should Probably Be Cautious
Conservative investors who need simple, predictable income, anyone uncomfortable with the idea of leverage amplifying losses during a market pullback, and investors drawn in purely by the ~18-20% yield without understanding that it comes from a genuinely more complex and higher-risk mechanism than a standard covered call fund should think carefully before allocating meaningfully to this category. A short, roughly one-year track record — spanning mostly favorable market conditions for the underlying dividend-stock baskets — also means these funds haven’t yet been tested through a sustained downturn.
Final Thoughts
DayMAX ETFs represent a genuinely novel structure in the Canadian ETF market: daily options writing, applied at scale, combined with modest leverage, aimed squarely at investors who want more frequent and higher income than a traditional monthly covered call fund provides. The early results — strong asset growth, double-digit total returns, and yields near 18-20% — suggest the strategy has worked reasonably well during its first year, helped by generally favorable conditions for the underlying dividend-stock baskets.
But the mechanics matter more than the headline yield. Daily 0DTE options carry real, well-documented risks around gamma sensitivity and fast-moving intraday volatility, and the 25% leverage overlay amplifies both the income and the downside in ways a plain covered call fund does not. As with any high-income option strategy, investors should judge these funds on total return over a full market cycle — not just the distribution rate — and treat the yield as compensation for a specific, identifiable set of risks rather than as free income.

Frequently Asked Questions
What are DayMAX ETFs?
DayMAX ETFs are a suite of Canadian income funds — CDAY, SDAY, QDAY, and BDAY — that write covered call options every trading day (0DTE options) rather than monthly, while applying roughly 25% leverage to enhance income and growth potential.
Why does CDAY write options on the S&P 500 instead of a Canadian index?
0DTE options are not currently available on Canadian indices, so CDAY holds Canadian dividend stocks but writes its daily options on the S&P 500 to execute the 0DTE strategy.
Are DayMAX ETFs riskier than traditional covered call ETFs?
Generally yes. Daily 0DTE options carry higher gamma sensitivity and faster-moving risk than monthly options, and the added 25% leverage amplifies both potential income and potential losses compared to an unlevered monthly covered call fund.
What is the current yield on CDAY, SDAY, and QDAY?
As of late July 2026, CDAY yielded approximately 18.24%, SDAY approximately 18.26%, and QDAY approximately 19.71%, based on Hamilton ETFs’ published fund data. These figures change regularly and are not guaranteed.
Are DayMAX ETFs eligible for TFSA or RRSP accounts?
Yes, all DayMAX ETFs are eligible for registered accounts including the TFSA, RRSP, RRIF, FHSA, and RESP.
