The iShares Core S&P 500 Index ETF (TSX: XUS) gives Canadians unhedged, Canadian-dollar exposure to the 500 largest U.S. companies, placing it at the crossroads of the two forces defining Wall Street this autumn: the artificial-intelligence momentum lifting mega-cap technology, and the rate risk stemming from a more hawkish Federal Reserve. After a strong August for American large-caps, XUS holders are weighing whether that momentum can survive a historically volatile September.

What It Actually Holds

XUS tracks the S&P 500 Index and trades in Canadian dollars on the Toronto Stock Exchange, offering a simple way to own America's largest companies. Managed by BlackRock, it holds an asset base in the region of $9 billion and carries a competitive management expense ratio of roughly 0.10%. The standard XUS units are unhedged, so returns reflect both the index's movement and shifts in the CAD/USD exchange rate; a hedged sibling, XSP, is available for investors who prefer to neutralize currency. XUS distributes on a regular schedule, with a modest Yield in keeping with the growth-oriented index.

What's Driving the Fund Now

The AI narrative remains the engine. Enthusiasm around chipmakers, hyperscalers and software leaders propelled the technology-heavy S&P 500 through August. But the rate backdrop has turned against richly valued growth stocks: hawkish signals around the Fed's Jackson Hole gathering, combined with a U.S. jobs report that came in roughly three times consensus, revived expectations of a September rate hike. For XUS specifically, currency adds a second dimension. As an unhedged fund, its Canadian-dollar returns are flattered when the U.S. dollar strengthens—often a consequence of hawkish Fed policy—and pressured if the loonie rebounds. With the Canada--U.S. trade dispute adding exchange-rate volatility, that currency effect could be as influential as the index's own move in the near term. The result is a fund whose outcome hinges on both U.S. macro data and the direction of the loonie.

Portfolio and Performance Picture

XUS mirrors the S&P 500's composition, dominated by mega-cap technology and communication-services names, with the top holdings concentrated in a handful of familiar giants. That concentration powered strong multi-year returns but heightens sensitivity to any pullback in the AI complex. Because it is unhedged, XUS's realized Canadian-dollar return can diverge from the headline U.S. figure depending on currency moves, and a foreign withholding-tax adjustment applies as with other CAD-listed S&P 500 funds. Its low fee keeps index tracking tight, and distributions are modest, reflecting the index's growth tilt rather than an income focus. The practical choice between XUS and its hedged sibling XSP often comes down to a view on the loonie. Investors who expect the Canadian dollar to weaken, or who prefer not to pay the ongoing cost of a currency hedge, tend to favour the unhedged XUS; those who want their return to track the index in Canadian-dollar terms lean toward the hedged version. Over long horizons the two have historically delivered similar results as currency effects average out, but in any single year the gap can be wide, which keeps the hedging decision front of mind for Canadian holders.

What Investors May Watch Next

The Federal Reserve's September decision and projections are the clearest catalyst, alongside U.S. inflation prints and the trajectory of the Canadian dollar. Investors may also watch whether AI-linked Earnings keep pace with elevated expectations. Risks include technology valuation risk given the concentration, interest-rate risk if the Fed tightens further, equity-market Volatility in a seasonally weak month, and currency fluctuations for unhedged unitholders.

Conclusion

XUS offers low-cost, unhedged access to the S&P 500 at a moment when AI optimism and a hawkish Fed are pulling markets in opposite directions. Its concentration and currency exposure define its near-term risk, but for long-term Canadian investors it remains a straightforward core U.S. holding.
