Gold prices extended gains for a third day in five after Federal Reserve Board Chair Janet Yellen repeated that any rate hikes by the Fed will be gradual. A gloomy outlook for quarterly corporate results has spurred risk-averse investors to pour money into safe-haven assets like bullion. The gold price June delivery rose 0.5% to settle at $1,243.80 a troy ounce on the Comex division of the New York Mercantile Exchange. The contract has added 1.7% this week, its best weekly gain in three weeks. In remarks late Thursday, Yellen said the Fed would "watch very carefully what is happening in the economy." "We think a gradual path of rate increases will be appropriate" given the progress the economy has made and is likely to continue to make, Yellen said. She was speaking as part of a panel discussion involving all the living chairs of the Federal Reserve past and present–Ben Bernanke, Paul Volcker, and Alan Greenspan. Any rate hikes by the Fed this year are viewed as bearish for the yellow metal which grapples with high yield bearing assets in increasing rate environments. -Grim Corporate Profit Outlook- Analysts are expecting profits of S&P 500 companies to be down 7.4% from a year ago, Reuters reported.
