Bullion strengthens as a decline in US home prices weighs on Treasury yields. Gold saw bids at the previous low (1615) and a surge above 1660 may have prompted some short interests to cover. A rally fueled by profit-taking will not be enough to reverse the price action unless the precious metal secures follow-up buying. 1670 used to be a demand zone from a rally earlier this month and has become a key resistance. Its breach would carry the price to the previous high at 1730. A break below 1615 would push gold to 1570.
