Topic
TSX & Canadian Equities
TSX-listed companies, earnings results, M&A, and what is moving Canadian equity markets.
Orientation
The Toronto Stock Exchange, operated by TMX Group, is the principal Canadian senior listing venue and one of the most sector-concentrated developed-market indices in the world. Financials, energy, and materials together exceed half the S&P/TSX Composite weight, leaving the index structurally different from the S&P 500 and unusually exposed to commodity cycles and Big Six bank earnings.
