P233 ORACLE 233 Sun17 Oct ITN 2210:01 BREAKTHROUGH FOR COPPER? Copper has risen £80 over the past week to challenge historic resistance levels at £900. Experts Prescot Commodities say that if £910 is reached a breakthrough to at least £1,050 is indicated. Silver, though, is overbought, say Prescots. Some short-term retracement from the 14-month high of 610p an ounce has to be expected. Gold, meanwhile, has a technically strong configuration but there could be a short-term reaction which will take December Comex to $420.
