Key Highlights

  • The BMO S&P 500 Index ETF (TSX:ZSP) is one of the most widely owned US Equity funds in Canada, and it enters September at the intersection of three powerful currents: the artificial-intelligence boom lifting mega-cap technology, sticky Inflation pressures.
  • The AI narrative remains central.
  • Over longer horizons ZSP has delivered competitive performance versus peers, and its low fee means tracking the index tightly—though, as with all CAD-listed S&P 500 funds.

The BMO S&P 500 Index ETF (TSX: ZSP) is one of the most widely owned U.S. equity funds in Canada, and it enters September at the intersection of three powerful currents: the artificial-intelligence boom lifting mega-cap technology, sticky inflation pressures, and a Federal Reserve that has turned notably more hawkish. After a robust August for American large-caps, investors holding ZSP are weighing whether the same forces that drove the rally could just as easily trigger a sharp Reversal in a historically volatile month.

What It Actually Holds

ZSP tracks the S&P 500 Index, giving Canadians exposure to roughly 500 of the largest U.S. companies through a single CAD-listed unit on the Toronto Stock Exchange. It holds the constituent securities directly and carries a management expense ratio of about 0.09%, making it one of the lowest-cost S&P 500 Options in the country, effectively tied with VFV. The standard ZSP units are unhedged, so returns incorporate movements in the CAD/USD Exchange Rate alongside the index. BMO also offers hedged and U.S.-dollar variants for investors who want to manage currency differently. The fund's Assets run into the tens of billions, reflecting deep liquidity.

What's Driving the Fund Now

The AI narrative remains central. Enthusiasm around chipmakers, hyperscalers and software leaders has propelled the technology-heavy S&P 500, and that momentum carried through August. But the rate backdrop has shifted against richly valued growth stocks. Commentary around the Fed's Jackson Hole conference pointed to a hawkish stance under Chair Warsh, and a much stronger-than-expected U.S. jobs report boosted expectations of a September rate hike—an outcome that would pressure credit-sensitive and high-multiple names. Inflation is the swing factor. If price pressures prove persistent, the Fed may keep policy tight for longer, lifting yields and challenging equity valuations. Conversely, evidence of cooling could reignite the bull case. For ZSP's Canadian holders, the currency angle matters too: a firmer U.S. dollar tends to support unhedged returns, while any strengthening of the loonie could offset index gains. The result is a fund whose near-term fate depends as much on macro data as on corporate performance.

Portfolio and Performance Picture

ZSP's portfolio is dominated by the familiar roster of American mega-caps, with information technology the largest sector weight and the top holdings concentrated in a handful of household names. That concentration has been the engine of strong multi-year returns, but it also heightens sensitivity to any pullback in the AI complex. Distributions are modest and paid quarterly, consistent with the index's growth orientation. Over longer horizons ZSP has delivered competitive performance versus peers, and its low fee means tracking the index tightly—though, as with all CAD-listed S&P 500 funds, currency and withholding-tax dynamics can cause the investor's realized return to differ from the headline U.S. figure.

What Investors May Watch Next

The Federal Reserve's September meeting and updated projections are the key near-term catalyst, alongside U.S. inflation prints and further signals on the labour market. Investors may also monitor whether AI-linked Earnings keep pace with elevated expectations, and how the Canadian dollar behaves. Risks worth weighing include technology valuation risk given the portfolio's concentration, interest-rate risk if the Fed tightens further, equity-market Volatility in a seasonally weak month, and currency fluctuations for unhedged unitholders.

Conclusion

ZSP offers cheap, liquid access to the S&P 500 at a time when AI optimism and a hawkish Fed are pulling markets in opposite directions. The same concentration that fuelled its gains now defines its risk. For long-term Canadian investors it remains a core holding, but September could test their tolerance for volatility.
