The S&P/TSX Composite closed at 35,697.49 on September 11, up 0.54 percent on the day but down 3.7 percent from the 52-week high of 37,069.11 set in August. The index has closed lower in six of the past ten sessions, even as WTI crude closed above $100 a barrel twice in the same stretch, a divergence that runs against how a commodity-linked index usually trades.
Technology and financial names have led the declines through the period, with base metals and mining issues also under pressure on individual sessions, notably September 8. Energy weighting inside the index has offset part of the drag, not reversed it.
Why Oil Strength Has Not Lifted the Index
A TSX Composite that falls while WTI rises above $100 twice in one week is not typical trading. The mechanical explanation is composition: energy is a large weight in the index but not the largest, and financials and technology names, sectors more exposed to the coming Federal Reserve decision than to the Strait of Hormuz, have been the heavier drag this month. Coverage of the September 8 session attributed the decline that day specifically to weakness in technology and financial shares alongside base metals.
The Bank of Canada decision to hold on September 2, together with the CPI release due this morning, adds a second and unrelated pressure point. A hotter than expected inflation print would weigh on rate-sensitive financial and real estate names in the same session energy names are likely tracking oil. The two forces do not necessarily offset each other; they can compound in the same direction on the index level even while moving in opposite directions underneath it.
The index has traded in a wide band over the past three weeks, a range this chart traces against the September 8 session most closely tied to the technology and financial weakness that has weighed on the broader tape.

What the Fed Decision Adds to the Picture
The Federal Reserve decision on September 16 is now the more immediate catalyst for the financial and technology weight inside the index than anything happening in the Strait of Hormuz. A Fed rate increase would pressure valuations across both sectors globally, adding a second and independent source of TSX weakness on top of whatever the CPI print does this morning.
For now, the read on the index is two stories running in parallel rather than one: energy strength from Hormuz-driven oil, and rate-sensitive weakness from the run-up to the Fed decision Wednesday. The net has been negative in three of the past four weeks.
