TORONTO - The Toronto stock market closed little changed Wednesday, weighed down by financials amid growing caution about the threat posed by high government debt levels.

The S&P/TSX composite index finished the day up 10.29 points at 11,379.22 as the market found support from higher mining stocks.

The Canadian dollar rose 0.84 of a cent to 94.83 cents US. The loonie had fallen nearly a cent against the greenback on Tuesday.

Investor nervousness increased Wednesday after Standard & Poor's lowered its outlook on Spain's debt rating to "negative" from "stable," reflecting "the risk of a downgrade within the next two years."

S&P had already cut Spain's rating from AAA to AA+ in January. On Tuesday, rival Fitch had downgraded its rating on Greece.

Moody's also cut the ratings of six Dubai government-linked companies, leaving all in junk status.

"When we get this continued bubbling situation in Dubai and the downgrade of Greece's credit rating, we now realize that it's not necessarily just the U.S. financial system or the European banking financial system but sovereign wealth funds," said Kathryn Del Greco, vice-president and investment adviser at TD Waterhouse private investment advice.

"And these global economies really can remind us that things are not solved yet and there still could be some fallout and some repercussions of the excesses of the previous few years."

Wednesday's weak showing followed four days of TSX declines that carved just over 400 points from the main index - a sign that investors are hard pressed right now to find a reason to extend a rally that has gone on practically non-stop since early March.

"I think this market needs to be fed good news to be able to get higher than where it is right now - this market needs something fundamentally surprising to take it to new levels," added Del Greco.

"I think the market is probably vulnerable to a correction. I know we have been talking about it for several months now and it still has yet to materialize, (but) the market feels tired."
