A big correction in LME nickel would be "too hard to ignore," despite the base metals' relatively indifferent response so far, says Man Financial's Ed Meir. Notes that trading conditions will likely be nervous, with a likely downward bias "until the nickel correction plays itself out." The US Fed meeting could provide more direction to metals through the equity markets, Meir adds. LME nickel is last at $44,100 a metric ton, -6% since Tuesday having gained 62% since the start of the year.
