Day Hagan Smart Sector ETF (SSUS)

The Day Hagan Smart Sector ETF (SSUS) owns stocks from all 11 economic sectors of the US market — Technology, Healthcare, Financials, Industrials, and the rest — but does not weight them by their market capitalization. Instead, it uses a rules-based algorithm to tilt the portfolio toward sectors that appear undervalued, have lower volatility, or rank well on other quantitative metrics. The fund rebalances quarterly to adjust these tilts as market conditions evolve.

The smart-beta philosophy

Smart-beta ETFs sit between two worlds. A passive market-cap-weighted index fund like the S&P 500 holds all stocks in proportion to their size — so if Technology is 30 percent of the market, it is 30 percent of the fund. An actively managed mutual fund hires a manager to pick individual stocks and make bets that that manager thinks will win. Smart-beta funds split the difference: they apply mechanical, rule-based decision rules to tilt a portfolio, without hiring a human stock picker.

SSUS uses what Day Hagan calls a Smart Sector Rotation strategy. The logic is that sectors move in cycles — Technology outperforms in booms, Utilities and Staples outperform in recessions, Financials benefit from rising rates, and so on. Rather than trying to predict which cycle is coming, SSUS measures each sector’s current valuation, volatility, and other objective metrics, then gradually rotates exposure toward the sectors that score best. It does not abandon poorly scoring sectors; it simply underweights them. The rebalancing happens quarterly, giving the fund enough stability to avoid excessive trading costs.

How the weighting formula works in practice

SSUS’s index weights each sector based on a composite score derived from metrics like price-to-earnings ratio, price-to-book ratio, volatility, and earnings growth. A sector trading at a cheap valuation and offering steady growth might earn 12 percent of the portfolio. A sector trading at a high multiple with falling earnings might earn 4 percent. Over time, as prices and earnings change, the scores shift, and the fund rebalances to match.

The effect is that SSUS tends to tilt toward value sectors (like Financials, Energy, and Industrials) when they are cheap and underowned, and toward Growth sectors (like Technology and Healthcare) when they look reasonably valued. In down markets, the value tilt can help — value sectors often hold up better because they are already cheap and offer dividends. In booming growth cycles, SSUS’s restraint on Technology exposure can feel like a drag, because cap-weighted funds load up on mega-cap tech names and outrun SSUS.

Sector allocation and cyclical behavior

On any given day, SSUS’s 11 sector weights might look roughly balanced — each sector between 5 and 15 percent, with none dominating — compared to a cap-weighted S&P 500, where Technology alone can be 25 to 30 percent. This makes SSUS less sensitive to mega-cap tech booms and busts. When Technology is soaring, SSUS lags. When Technology craters (as it did in 2022), SSUS’s lower weight provides some cushion.

The fund performs best in environments where neglected or undervalued sectors outperform the market darlings. In the 2000s, when value and commodity-linked sectors led, SSUS would have shone. In the 2010s and 2020s, when mega-cap tech was the dominant driver of returns, cap-weighted funds beat it. Going forward, that pattern could easily reverse — if a major economic cycle shift occurs, or if interest rates stay high and boost Financial sector earnings relative to Technology, SSUS’s rules-based tilt could outperform.

Costs, expenses, and implementation

SSUS’s expense ratio is typically in the 0.50 to 0.60 percent range — higher than a basic S&P 500 ETF but much lower than an actively managed fund. The quarterly rebalancing creates some trading costs and potential tax inefficiencies, though these are modest. The fund trades on the NASDAQ with decent daily volume, and most brokers can execute buys and sells without friction.

Because SSUS holds all 11 sectors, it offers broad US market exposure — you are not concentrated in mega-cap tech or any single industry. That is its strength. It is also its weakness: if the winning strategy for a given cycle is to go all-in on one sector, SSUS’s diversified approach will lag the optimal bet.

Who SSUS appeals to and how to use it

SSUS is designed for investors who want US stock exposure but believe that equal-weighting or cap-weighting misses opportunities in sector rotation. It appeals to those with a philosophy that cheap, stable sectors will outperform over time, or who simply want to reduce their portfolio’s concentration in mega-cap tech without making explicit tactical bets.

The fund also works as a diversifier within a portfolio. An investor holding a core S&P 500 ETF could add SSUS to introduce a quantitative tilt toward value and lower volatility, creating a blended portfolio that is neither purely passive nor actively managed. Some investors use it as a “rules-based alternative” to trying to time sector rotations by hand — letting the algorithm do the tilting rather than making emotional calls about which sector will win next.

Research SSUS by reviewing the fund’s prospectus and methodology documentation, available on the sponsor’s website, to understand exactly which metrics drive the sector scoring. Check the current sector weights and compare them to a cap-weighted benchmark like the S&P 500 to see where the fund is tilting. Watch how the fund performs relative to cap-weighted US stock funds through different market cycles — you will see periods where SSUS wins (usually when value and lower-volatility sectors lead) and periods where it lags (usually when mega-cap growth leads). The fund’s live-stream return depends entirely on whether the next phase of the market cycle favors its tilt.
