Market Analysis—September 23, 2026
Oil and Yields Interrupt North America’s Rally
North American stocks are retreating after the Nasdaq’s record close and the TSX’s strong gain on Tuesday. The selloff is broad: small caps are falling more than the major U.S. indexes, while Canadian miners and technology stocks are weighing heavily on Toronto. The immediate pressure comes from oil moving back above US$100 a barrel, rising bond yields and a U.S. business survey that points to both stronger growth and higher costs.
Brent crude has pushed back above US$100 after several days of declines. At the same time, the U.S. 10-year Treasury yield has moved above 5%, a level that puts pressure on the valuations of growth stocks and raises borrowing costs across the economy. Canada’s 10-year yield is also rising. Higher oil prices can add to inflation, making it harder for central banks to ease policy and giving bond yields another reason to climb.
Today’s economic data sharpened that concern. The flash U.S. composite PMI rose to 58.4 in September from 56.0 in August, indicating faster business growth. The survey also reported a jump in input costs and worsening supply delays. Strong demand supports corporate revenue, but it may also keep the Federal Reserve focused on inflation and further rate increases.
Has the recent technical advance broken?
The Nasdaq has slipped below 27,000 after closing at a record 27,244 on Tuesday. The TSX has fallen below 36,000, reversing much of its latest push higher. Those moves interrupt the short run upward and make today’s close important: a recovery above those levels would suggest buyers are still defending the advance; a weak close would strengthen the case for a deeper pullback.
The evidence does not yet establish a lasting breakdown in the broader U.S. trend. At midday, the S&P 500 and Nasdaq remain above their September 18 closes. The Russell 2000’s sharper decline is a concern because it shows that smaller, more rate-sensitive companies are absorbing more of the pressure. Traders are watching whether selling broadens further and whether oil and yields remain elevated into the close.
Stocks in focus
Nvidia (NVDA), AMD and Intel (INTC) are testing the durability of the semiconductor rally as chip shares come under pressure. Meta (META) has been comparatively resilient following enthusiasm for its AI assistant, making it a useful gauge of whether investors are still willing to hold the recent AI winners.
In Canada, Shopify (SHOP:CA) is pulling back after its sharp two-day rise tied to an AI shopping partnership with Meta. Endeavour Silver (EDR:CA) is under particular pressure after CIBC downgraded it, while NovaGold (NG:CA) and other miners are falling with precious metals. Suncor (SU:CA) and Canadian Natural Resources (CNQ:CA) remain worth watching for relative strength as crude rebounds, even though stronger oil is creating a tougher backdrop for the overall market.
Today looks like a test of the rally rather than a confirmed change in the longer-term trend. For the market to regain momentum, oil and yields need to settle and buyers need to return beyond a few AI stocks. A close near the day’s lows, particularly with the TSX below 36,000 and the Nasdaq below 27,000, would point to more consolidation ahead.
Market Analysis—September 22, 2026
North American stocks enter Wednesday with a positive but uneven backdrop. The Nasdaq rose 0.45% on Tuesday to a record close of 27,244.28, supported by semiconductor and other AI-related shares. The S&P 500 finished virtually unchanged at 7,764.64, while the Dow fell 0.36%. Investors are still buying growth stocks, but the broader U.S. market has yet to match the Nasdaq’s momentum.
Canadian stocks had a stronger session. The S&P/TSX Composite gained 326 points, or 0.9%, to 36,335.61, its highest close in nearly three weeks. Materials, technology and industrials led the advance, with Shopify rising 7.4%. Financials and energy declined, however, so continued gains will depend on strength extending beyond the day’s leading sectors.
Oil is the market’s immediate test. U.S. crude settled 1.2% lower at $94.59 a barrel as hopes for progress between Washington and Tehran eased supply concerns. A sustained decline could relieve inflation pressure and support growth stocks. A reversal would put bond yields and interest rate expectations back in focus.
The Federal Reserve remains cautious. Richmond Fed President Tom Barkin said Tuesday that U.S. economic activity appears to be firming and that inflation pressures extend beyond energy and tariffs. That leaves investors weighing resilient demand against the prospect of further rate increases. Wednesday’s flash U.S. manufacturing and services PMI readings, due at 9:45 a.m. Eastern, may offer the next indication of whether growth is holding up without another acceleration in prices.
The near-term trend remains positive, led by AI shares in the U.S. and technology and miners in Canada. The rally would look stronger if U.S. financials stabilized and TSX gains broadened further. If oil stays contained and the PMI readings show steady growth, stocks could extend their advance. If crude and yields rise together, both the Nasdaq’s record and the TSX’s rebound may face a tougher test.
