TORONTO -- Stock indexes in North America saw little change, as traders played it safe a day before an interest rate announcement by the U.S. Federal Reserve.

In Toronto, gains in the gold and mining sectors helped propel the S&P/TSX composite index up a modest 51.90 points to 14,550.

It was a similarly ho-hum mood on Wall Street.

The Dow Jones industrial average was down 19.31 points at 18,473.75, while the broader S&P 500 composite index gained 0.70 of a point to 2,169.18. The Nasdaq composite added 12.42 points to 5,110.05.

The Canadian dollar was up 0.18 of a U.S. cent to 75.82 cents US, as the September crude contract faded 21 cents at US$42.92 per barrel.

In other commodities, the September natural gas was down four cents at US$2.68, while the August gold contract gained $1.30 to US$1,320.80 an ounce and September copper contracts rose one cent to US$2.23 pound.
