The Globe and Mail reports in its Saturday edition that S&P Dow Jones Indices is deleting Canada Goose Holdings from the S&P/TSX Composite Index. The Globe's David Milstead writes that S&P will also delete Ballard Power Systems, Africa Oil, Canfor and Westshore Terminals Investment. It will add Bird Construction and Triple Flag Precious Metals. The changes will be effective at the open of markets on Sept. 23. No changes are being made to the S&P/TSX 60, a selection of the largest companies in the composite. Canada Goose, which has a $1.4-billion market capitalization, listed in Toronto and New York when it went public in 2017. Chief executive officer Dani Reiss built the brand around a "Made In Canada" mantra. However, the majority of trading in the company's shares now takes place on the New York Stock Exchange. S&P Dow Jones uses "float" -- the value of shares that are not held by insiders and that therefore trade frequently and are easily available to the public -- to judge whether a company should be included in its indexes. Earlier this year, ATB analysts estimated index-related demand accounts for an average of 5.5 per cent of the float of an S&P/TSX Composite member company.
