The S&P/TSX Composite ended Tuesday, September 15, 2026, at 35,582.07, down 120.46 points or 0.34%. Energy’s 3.1% gain was insufficient to offset weakness elsewhere: Reuters reported that it was the only major Canadian sector to finish higher.

The index opened 20.35 points below Monday’s finish but reached a high 2.80 points above that previous close. Unlike a session confined entirely below its starting reference, Tuesday’s reported range included both positive and negative territory versus Monday.
The 299.70-point range was approximately 0.84% of the previous close. At the finish, the benchmark was 176.44 points above its low and 123.26 points below its high, placing the close about 59% of the way up the range. It nevertheless ended 100.11 points below the opening level.
Reuters recorded declines of 2.6% in consumer discretionary, 2.1% in consumer staples and 1.6% in technology. Its report linked the broader weakness to rising bond yields and concerns about tighter U.S. monetary policy. These are attributed market explanations, not causal conclusions derived from the daily bar.
S&P Dow Jones Indices identifies the Composite as Canada’s headline equity benchmark and the broadest index in the S&P/TSX family. Its cash-index level should not be confused with the narrower TSX 60 or a Canadian equity ETF price.
The Federal Reserve calendar schedules the U.S. policy meeting for September 15–16; this article does not presume the decision.
