Market Context

The TSX Composite closed out a genuinely volatile week having weathered one of its sharper single-day declines in recent memory, followed by a solid rebound, as investors absorbed a contentious Federal Reserve decision, renewed Middle East tensions, and a wave of pivotal megacap technology earnings, all within the span of just a few trading sessions.

What Happened

The TSX Composite fell nearly 1% to below 35,500 Wednesday, weighed down by financials and miners, after the Federal Reserve held rates steady at 3.50% to 3.75% but with three dissenting votes favouring a hike, an outcome that pushed the Dow down more than 1,150 points and sent the 30-year Treasury yield to its highest level since 2007. Oil prices had risen the same day as Middle East tensions escalated following joint U.S.-Saudi strikes in Iraq. RBC fell 3% and TD Bank lost 3.2%, while Shopify declined 1.2% and Celestica dropped 6.2% ahead of Microsoft’s and Meta’s earnings reports and amid a broader U.S. chip stock selloff. Energy stocks bucked the trend, with Canadian Natural Resources gaining 4.6% and Cenovus adding 4.5% on stronger quarterly results. The index rebounded Thursday, rising 0.49% to close at 35,505.84, with RBC gaining 1.39% and Bank of Nova Scotia adding 1.62%, as U.S. markets rallied sharply following Microsoft’s earnings report, which showed the company beating estimates with $4.74 in earnings per share and $90 billion in revenue while guiding to steady 2026 capital expenditures, easing broader AI spending concerns. Meta shares fell roughly 9% the same day after issuing a weaker-than-expected revenue forecast and disclosing a 91% year-over-year drop in free cash flow. Separately, U.S. second-quarter GDP grew just 1.5%, below the 1.8% forecast, while core PCE inflation, the Fed’s preferred gauge, rose 0.1% monthly and 3.3% annually, in line with expectations.

Why It Matters

This week’s whipsaw between Wednesday’s sharp decline and Thursday’s solid rebound illustrates how sensitive markets remain to the combination of monetary policy uncertainty and megacap earnings outcomes. The scale of Wednesday’s move, driven by a Fed decision that was itself contentious even among policymakers, followed by Thursday’s recovery on the back of a single strong earnings report from Microsoft, underscores just how concentrated market-moving power has become among a handful of major catalysts.

The diverging reactions to Microsoft’s and Meta’s results highlight a market becoming genuinely more discerning about AI spending. Microsoft’s ability to guide toward steady, rather than escalating, capital expenditures while still delivering strong growth was rewarded, while Meta’s weaker forecast and sharp free cash flow decline was punished, suggesting investors are now differentiating clearly between AI spending that translates into visible returns and spending that doesn’t.

Sector Breakdown

Financials experienced the week’s sharpest swings, falling meaningfully Wednesday on rising bond yields before rebounding Thursday as broader risk appetite improved. Technology showed a genuinely split story, with Celestica pressured ahead of the megacap earnings wave while Constellation Software gained 3.2% the same session, and the sector broadly benefiting Thursday from Microsoft’s strong results. Energy remained a consistent source of strength throughout the week, benefiting from both renewed oil price gains and solid company-specific earnings from Cenovus and Canadian Natural Resources.

Risks to Watch

The most significant risk is that this week’s contentious Fed decision, with three dissents favouring a hike, signals a genuine shift toward tighter policy at the September meeting, which could pressure equity valuations broadly if bond yields continue climbing. Continued volatility in Middle East tensions, following this week’s U.S.-Saudi strikes, could extend the oil price volatility that has characterized much of this month. Apple’s mixed earnings report, released after Thursday’s close showing a beat on both revenue and earnings but weak forward guidance citing supply constraints, adds a further variable for today’s session given the stock’s decline of more than 6% in extended trading.

What to Watch Next

Investors should watch today’s market reaction to Apple’s earnings report closely, given the stock’s sharp after-hours decline following otherwise solid results. Continued developments following this week’s Middle East escalation will remain relevant for both oil prices and broader market sentiment. The Fed’s next scheduled meeting, September 15-16, will be closely watched for confirmation of whether this week’s dissents translate into an actual rate hike.

Final Outlook

The TSX’s round trip from Wednesday’s sharp decline to Thursday’s solid rebound reflects a market genuinely working through a dense combination of monetary policy uncertainty, geopolitical volatility, and pivotal earnings outcomes within a single week. With Apple’s mixed report still being digested today, investors should expect continued volatility rather than a settled direction in the immediate term.

Verdict: Cautiously constructive, with today’s reaction to Apple’s earnings as a near-term test of market resilience.
