TORONTO, July 3 (Reuters) - Toronto's main stock index rose on Friday morning, boosted in part by Teck Resources Ltd's TCKb.TO equity sale to China Investment Corp.
Teck said on Friday it will sell a 17.2 percent stake to state-owned CIC through a private placement that will raise C$1.74 billion ($1.5 billion). [ID:nN03153079]
Teck shares rose 3.3 percent to C$19.19 and helped boost the broader materials sector, which climbed 0.75 percent.
"The main story on a very quiet with no volume day is the Teck story," said Francis Campeau, a broker at MF Global Canada in Montreal. "It has been interpreted by the market as a positive."
At 10:27 a.m. (1427 GMT), the S&P/TSX composite index .GSPTSE was up 31.33 points, 0.31 percent, at 10,277.24 Six of its 10 main groups were higher. Trading was thin with influential U.S. markets closed to observe the Independence Day holiday.
Financials rose 0.62 percent after the sector fell for two straight sessions. Manulife Financial (MFC.TO) was up 1.06 percent at C$20.03.
