What is the TSX, in plain English
The S&P/TSX Composite is the main measure of the Canadian stock market. Here is what is in it and why it moves differently from US markets.
When Canadian news reports on "the TSX", it almost always means the S&P/TSX Composite Index. It is the main scorecard for Canada's stock market.
Two names that get mixed up
The Toronto Stock Exchange is the marketplace where shares of Canadian companies are bought and sold.
The S&P/TSX Composite Index is a list of the larger companies that trade there, turned into one number. When the news says "the TSX rose 1%", it means this index.
What is in it
The index holds a few hundred of the largest companies on the Toronto Stock Exchange. Like the S&P 500, it is weighted by size, so the biggest companies move it the most.
What makes it different is the mix. Three groups carry a lot of the weight:
- Banks and insurers. The big Canadian banks are among the largest companies in the index.
- Energy. Oil and gas producers and pipeline companies.
- Materials. Gold, copper and other mining companies.
Why that matters
Because of that mix, the TSX often moves with oil prices, metal prices and interest rates. A day when oil jumps can be a good day for the TSX even if US technology stocks fall. A day when gold drops can pull it down even when US markets rise.
The US S&P 500 has much more weight in technology companies. That is the main reason the two markets do not always move together.
The short version
- "The TSX" in the news means the S&P/TSX Composite Index.
- It is weighted toward banks, energy and mining.
- Oil, metals and interest rates move it more than they move US markets.
