Speakers and attendees at the Platts Aluminum Symposium 2007, being held in Scottsdale, Ariz., look for lower aluminum prices later in the year. Michael Skinner, base metals sales at Standard Bank, asked an audience for a show of hands on who thinks prices will be higher or lower a year from now, and a large majority indicated lower. Skinner and others presenting at the symposium agree. Skinner says aluminum could reach $3,200 a metric ton in the first half of the year, but he looks for it to fall back an average somewhere in in the $2,500s for the whole year. Craig Tuckman, managing director Merrill Lynch Commodities, looks for a low of $2,350 this year, with an average of perhaps $2,450.
