The financial indexing firm S&P Dow Jones Indices will delete the software company Docebo, the Bitcoin-mining company Hut 8 Mining, the electric-vehicle maker Lion Electric, the auto-parts maker Martinrea and the heath-technology company Well Health from the S&P/TSX Composite Index on June 20.

Talking point: The market is in the middle of a technology rout and the S&P/TSX Composite Index is a widely tracked group. Nonetheless, several of the companies being deleted from the index will still have wide exposure on U.S. exchanges. For example, Lion Electric also trades on the New York Stock Exchange and Docebo is listed on the Nasdaq. Meanwhile, Well is fresh off a funding spree. The index has quite a few requirements for constituents around trading volume, liquidity, market capitalization and share classes. The new additions to the S&P/TSX Composite Index include four oil and gas-industry companies, a mining company and an insurer.
