(Updates prices, sectors)

July 16 (Reuters) - Canada's main stock index was muted on Friday, and on track to post a weekly loss of half a percent as energy stocks took a beating from lower oil prices.

* The energy sector tumbled nearly 6% this week and is set for its worst week in nearly four months, as crude prices tumbled.

* However, the sector gained 0.6% on Friday and kept the main index afloat.

* At 9:42 a.m. ET (1342 GMT), the Toronto Stock Exchange's S&P/TSX composite index was up 2.83 points, or 0.01%, at 20,186.55.

* Data showed the nation's wholesale trade increased by 0.5% in May from April on the food, beverage and tobacco subsector as well as machinery and equipment.

* The materials sector, which includes precious and base metals miners and fertilizer companies, lost 0.8% as gold futures fell 0.2% to $1,824.5 an ounce.

* On the TSX, 133 issues were higher, while 87 issues declined for a 1.53-to-1 ratio favouring gainers, with 12.22 million shares traded.

* The largest percentage gainer on the TSX was Methanex Corp (MEOH) , which jumped 6.2%, after the methanol producer raised its quarterly divided.

* Alt-energy producer Westport Fuel Systems Inc (WPRT) followed with a 3.3% rise.

* Turquoise Hill Resources Ltd (TRQ) fell 12.7%, the most on the TSX, after multiple brokerages cut their price targets on the stock. The second biggest decliner was B2Gold Corp (BTG), down 4.3% after National Bank of Canada cut its price target on the miner.

* The most heavily traded shares by volume were Royal Bank of Canada (RY), B2Gold Corp (BTG) and Baytex Energy Corp (BTEGF) .

* The TSX posted no new 52-week high and no new low.

* Across all Canadian issues there were 50 new 52-week highs and four new lows, with total volume of 22.06 million shares. (Reporting by Amal S in Bengaluru; Editing by Amy Caren Daniel)
