Gold futures fell 0.8% to $4,385.90 a troy ounce and spot gold was 0.3% lower at $4,335.63 per ounce, as investors took profits following this week's rally. Prices had surged above $4,400 earlier in the week due to softer inflation data, which reduced expectations of a Federal Reserve rate hike in September. Analysts suggest the broader uptrend remains intact but profit-taking is occurring after the sharp rally, with $4,300 per ounce seen as an immediate support level.
