Market Context
The S&P/TSX Composite’s statistical position on September 22 is defined by two numbers that appear to contradict each other but together tell a complete analytical story. Over the past month, the index has declined 1.64%. Over the past year, it has gained 20.28%. That juxtaposition is not a paradox — it is an accurate summary of the 2026 Canadian equity market’s trajectory: a remarkable year of exceptional performance, followed by a September in which multiple macro shocks — the Saudi pipeline closure, the Fed’s first rate hike in three years, the Canada-U.S. tariff escalation, and the AI industry’s “pace the frontier” debate — have created month-over-month selling pressure that the underlying fundamentals are not fully supporting.
The TSX’s three-year average P/E ratio, as reported by Simply Wall St, stands at 21.6x, and the market is currently trading close to that historical average — a notable data point suggesting the index is neither significantly overvalued nor a screaming bargain at current levels. Canadian listed company earnings have grown 12% annually over three years, with revenues growing 3.7% annually, confirming that the earnings multiple expansion is partially supported by real operational growth rather than purely by multiple inflation. The Bank of Canada’s Governor Macklem warned on September 21 in Halifax that U.S. trade policy unpredictability “could set back the recent progress by the Canadian economy” — the most direct and sobering BoC assessment of the trade war’s structural economic risk in recent weeks.
Trump’s announcement on September 21 of working toward a “massive deal” to purchase potash from Belarus added a specific and unexpected trade war dimension: if successful, it would directly undermine one of Canada’s most significant commodity leverage positions in the dispute, reducing the potash export restriction option that premiers had been discussing. For the broader investor report, that development confirms a pattern: the Trump administration is actively working to reduce U.S. dependence on Canadian commodities across multiple categories (energy, agriculture, materials), a systematic de-risking of the bilateral relationship that has long-term implications for Canadian resource sector valuations.
What Happened
Friday September 18’s session — the most recently completed full trading day — delivered a 0.2% TSX decline to 35,807 as Canadian bond yields edged higher on persistent energy-driven inflation concerns. The session was characterised by “broad-based losses capping off a week where the index had largely struggled to find direction,” according to Trading Economics. Financial stocks were mixed: Fairfax Financial lost 2.6% and RBC edged 0.2% lower, while TD Bank rose 0.6%. Gold miners reversed Thursday’s gains: Agnico Eagle lost 1.1%, Barrick shed 1.5%, and WPM fell 1%. Technology stocks were split: Shopify declined 0.4% on U.S. hyperscaler weakness, while Celestica gained 0.7% and Constellation Software added 0.5% amid Wall Street chipmaker strength. Monday September 21’s session saw the index edge lower again as Governor Macklem’s speech in Halifax provided the dominant domestic narrative, alongside Trump’s potash-Belarus announcement from the U.S. side. BMO at CA$240.52 — up 32.4% year-to-date — sits as one of the week’s most analytically instructive data points: a major Canadian financial institution whose share price is approaching levels where even quality dividend investors must reassess the forward return opportunity versus the forward risk.
Why It Matters
Macklem’s Halifax Warning Is the BoC’s Most Direct Trade War Acknowledgement
Governor Macklem’s September 21 statement that U.S. trade policy unpredictability “could set back the recent progress by the Canadian economy” is analytically significant for what it signals about the Bank of Canada’s internal assessment. The BoC does not typically use language this specific about external risks unless the Governing Council’s consensus view is that those risks have become material enough to warrant explicit public acknowledgement. Read in conjunction with the BoC’s September 2 hold — where Macklem said “monetary policy cannot offset the effects of tariffs or global energy prices” — Monday’s Halifax speech suggests the central bank is increasingly concerned that the trade war’s second and third-order effects (business investment contraction, consumer confidence deterioration, currency depreciation) are building at a rate that may require reassessment at the October 28 decision.
The Technology Split on Friday Signals Macro Differentiation Within the Sector
The Friday technology divergence — Shopify down 0.4% on hyperscaler weakness while Celestica gained 0.7% on chipmaker strength — is analytically revealing. The market is continuing to distinguish between AI platform companies (whose revenues are software-based and less directly tied to semiconductor spending cycles) and AI infrastructure manufacturers (whose revenues are directly tied to hardware orders from data centre customers). When chipmakers gain, Celestica gains — its revenue is tied to the same semiconductor and AI hardware demand cycle. When hyperscalers weaken, Shopify faces multiple compression as its platform-adjacent AI story becomes less compelling to growth investors. That differentiation is not new, but it is sharpening as September’s macro events clarify which companies’ earnings are most sensitive to which macro variables.
Sector Breakdown
The TSX’s current sector composition and performance profile on September 22 reflects a market in transition from the extraordinary energy-and-gold-driven gains of H1 2026 to a more nuanced second-half environment where sector differentiation matters more than directional index bets. Energy — which was the week’s standout H1 performer — is normalising as the Saudi pipeline partial restoration removes the emergency supply premium. Gold and materials — which had rallied on safe-haven demand and geopolitical risk through September 14’s peak — are absorbing post-hike real yield pressure. Financials — with BMO’s 32.4% YTD gain as the benchmark — continue demonstrating earnings quality resilience but face valuation and rate-competition questions at current levels. Technology — split between AI infrastructure momentum (Celestica) and platform multiple compression (Shopify) — is navigating the post-hike discount rate environment with more internal dispersion than at any point in 2026.

Risks to Watch
The October Fed hike remains the primary forward risk for the TSX. Governor Macklem’s trade war warning signals that the October 28 BoC decision may be more consequential than the market currently prices. The September 29 tariff expansion — now seven days away — is the next formal trade escalation event. Trump’s Belarus potash deal announcement is a geopolitical development that could mature into a commercial reality over months, affecting Canadian resource sector competitive positioning. BlackBerry’s September 24 earnings — two days away — represent the most important company-specific binary event remaining in September.
What to Watch Next
BlackBerry’s September 24 earnings at 8:00 a.m. EDT are the week’s most important company-specific catalyst. September 29’s tariff expansion effective date is the next formal trade war escalation event. October 28’s Bank of Canada rate decision will be the most consequential domestic monetary policy event of the autumn. The economic data between now and the October FOMC will determine whether the dot-plot’s hawkish consensus results in a second 2026 hike. Any clarity on the Belarus potash deal — specific supply volumes, pricing terms, delivery timelines — will define whether Canada’s potash leverage is materially affected.
Final Outlook
The TSX at a 20.28% year-over-year gain and a 1.64% one-month decline is navigating the specific tension between exceptional underlying corporate performance and a macro environment that has, in September alone, introduced a Fed rate hike, trade war escalation, Saudi supply disruption, AI sector uncertainty, and a Governor Macklem warning about trade policy risk. That combination is unusual in its simultaneity but not unprecedented in its individual components.
Investors who maintain analytical discipline — distinguishing between macro-driven price pressure and fundamental earnings deterioration — will find that the TSX’s current 21.6x historical average P/E level represents a market that has fairly absorbed this September’s shocks rather than one that has dramatically mispriced them in either direction.
Verdict: Cautiously constructive at the index level. The TSX’s P/E near its three-year average suggests fair rather than extreme valuation. Sector positioning matters: energy and banks remain the quality anchors; technology benefits from stock-specific differentiation; gold mining names await October FOMC clarity. BlackBerry’s September 24 earnings are the week’s most important catalyst.
