IShares Edge S&P 500 Minimum Volatility ETF offers a portfolio of US stocks that have been selected to deliver the lowest possible variance of returns. The underlying index strategy starts with the stocks in the well-known S&P 500 and then uses an optimizer to create the optimal minimum-volatility portfolio. In doing so, the fund aims to provide a smoother ride through the US equity markets by lowering volatility and reducing downside capture.
While the strategy generally adds value by limiting losses during broad market selloffs, investors should bear in mind that such a defensive posture comes at the cost of lagging during strong bull markets. This is characteristic of the strategy’s objective to deliver a portfolio inherently less correlated with market returns. Investors should also note that although the strategy aims to build the portfolio with the lowest possible variance, the underlying portfolio can contain average- to high-volatility stocks for the risk diversification benefits they carry. This sets the minimum-volatility strategy apart from other low-volatility strategies that hold only low-volatility stocks, irrespective of how the final portfolio looks. Investors who are specifically seeking funds that hold low-volatility stocks exclusively or who are uncomfortable with high-volatility stocks are advised to look elsewhere.
The fund has largely performed as expected. Delivering relatively strong returns in times of market turbulence, such as 2022, when investors grappled with economic turbulence, including rising inflation, fluctuating markets, losses in tech, and cryptocurrency downturns amid ongoing pandemic challenges. The fund’s defensive positioning saw it outperform its average peer by 9% over the year.
The defensive positioning also saw the fund offer a smoother ride to investors throughout the tariff-related turmoil of early 2025, although this strategy lagged in the subsequent market rally, overall leading to superior risk-adjusted returns relative to peers in 2025.
The fund’s ongoing charge positions it attractively against active peers in its category.
When it comes to investing passively in US equities, fund domicile and replication method are crucial because they dictate how much withholding tax an investor must pay. This fund is domiciled in Ireland and therefore pays 15% rather than the standard 30% withholding tax assumed by the index. For this reason, this fund regularly outperforms its index. That said, this fund is at a disadvantage versus synthetically replicated peers, who pay no withholding tax.
Additionally, the fund benefits from being managed by BlackRock, whose industry-leading technology, global footprint, and extensive supporting cast earn an Above Average People Pillar rating.
iShares Edge S&P 500 Minimum Volatility UCITS ETF: Performance Highlights
The fund’s risk-adjusted returns were lower than the US large-cap blend category average over the trailing three-, five-, and 10-year periods ended March 2026.
The strategy is designed to deliver lower volatility than the S&P 500, and it has largely achieved this objective. The ETF has exhibited lower standard deviation across three-, five-, and 10-year periods relative to both the index and category peers.
It has also demonstrated strong downside protection, with lower downside-capture ratios across one-, three-, five-, and 10-year periods. This reflects a portfolio that is less sensitive to market swings, partly driven by the 2% maximum position size constraint, which enhances diversification and limits concentration risk.
However, during the coronavirus-driven selloff in early 2020, which saw panic selling across asset classes, the fund did not provide superior downside protection and lagged in the subsequent recovery, returning 8.2% versus 17.7% for the category.
Conversely, during the “tech reckoning” of 2022, the strategy proved more resilient, declining 11.1% versus 19.6% for the category. In 2023 and 2024, amid strong US equity markets, the fund underperformed the EAA US large-cap blend category average.
US equities experienced significant volatility in 2025. Following the tariff announcement on April 2, markets fell by more than 19% before rebounding after Donald Trump announced a pause on tariffs on April 9. Despite this, large- and mid-cap US equities rose around 17% in US dollar terms, driven by artificial intelligence-related stocks in the technology and communication-services sectors.
Against this backdrop, the fund delivered a smoother ride than peers in the first half of 2025 but lagged during the second-half rally. This resulted in absolute underperformance, although it had superior risk-adjusted returns for 2025.
