Sept 25 (Reuters) - Canada's main stock index ended

lower on Wednesday as a drop in oil prices weighed on energy

shares and investors took stock of recent gains for the index

that had lifted it to an all-time high.

The Toronto Stock Exchange's S&P/TSX composite index

ended down 46.34 points, or 0.2%, at 23,905.88, after

four straight days of gains.

On Tuesday, the TSX posted a record closing high as China's

stimulus package boosted investor sentiment globally.

"I don't think there is anything to be read into this tape.

It is just a tape that's taking a breather and a bit more of a

defensive tone," said Christine Tan, a portfolio manager at SLGI

Asset Management Inc.

U.S. benchmark the S&P 500 also edged lower as investors

awaited further economic indicators and signals on upcoming

interest rate cuts. The Federal Reserve and the Bank of Canada

have begun easing campaigns.

"Now that rates are starting to come down, I think investors

are starting to think about the sectors that have lagged,

sectors that are more economically sensitive," Tan said.

"Usually when central banks start to cut rates, at some

point the economy starts to bottom out and starts to recover."

The energy sector fell 1.8% as the price of oil

settled 2.6% lower at $69.69 a barrel on easing worries over

supply disruptions in Libya.

Consumer discretionary fell 1.2%, weighed by a decline of

5.5% for the shares of Magna International ( MGA ) after Morgan

Stanley downgraded the stock to "equal-weight" from

"overweight". Industrials also lost ground, falling 0.6%.

Lightspeed Commerce Inc ( LSPD ) was a bright spot. Shares

of the payments software maker jumped 13.3% after sources told

Reuters that the company is working with a financial adviser to

explore options, including a potential sale.
