* Eight groups advance, financials lead
* Oil falls more than $1/barrel, weighs on energy sector
* Sliding gold price leads materials group lower
TORONTO, Dec 30 (Reuters) - Toronto’s main stock index rose on Tuesday morning as advances in financial and industrial shares offset declines in resources on retreating gold and oil prices.
At 10:30 a.m. (1500 GMT), the Toronto Stock Exchange’s S&P/TSX composite index .GSPTSE was up 52.54 points, or 0.61 percent, at 8,689.83.
The index began the session slightly lower but gains from eight of the index’s 10 main groups outweighed a drag from the oil and gas and materials sectors, which had advanced strongly in the previous session.
The industrial, consumer discretionary, retailers and telecoms were all more than 1 percent higher.
Oil fell below $40 a barrel, pressured by gloom about prospects for world economic growth which outweighed heightened tensions in the Middle East due to the Israeli-Hamas conflict. For details, see [ID:nSIN393322].
The materials sector was off 1.1 percent, as gold miners slumped alongside lower gold prices while rising fertilizer issues and other miners provided an offset.
Volume is expected to be light again with the trading week shortened by the New Year’s Day holiday on Thursday.
