Gold ended the day almost unchanged on Monday, taking a breather after dropping the most in a month in the previous session, as markets digested a decision by Standard & Poor's to revise the sovereign credit outlook for the United States to stable from negative.

Bullion's reaction to the announcement by the credit rating agency was largely muted. In August 2011, S&P downgraded the sovereign U.S. credit rating from top-rated AAA to AA-plus, heightening economic uncertainty that helped lift gold to a record high $1,920 a month later.
