TECH/C Holdings of SPDR Gold Trust GLD, the world's largest gold-backed exchange-traded fund, rose 0.6% on Wednesday. By Brijesh Patel June 10 (Reuters) - Gold prices were on the back foot on Thursday as the dollar ticked higher but traded in a narrow range as investors turned cautious ahead of the European Central Bank meeting and U.S. inflation data later in the day. "Sentiment is neutral and cautious going into CPI and the ECB meeting tonight," said IG Market analyst Kyle Rodda, adding that investors expect inflation to be contained, which is keeping a lid on the metal's price.
