A large cancelation of tin warrants from Singapore warehouses overnight should add to bullish LME three-month tin momentum this session, says a broker, but notes that the base metals complex as a whole looks a bit overbought. "They're up here on money," he says, adding that future direction is dependent on how much fresh fund inflow offsets profit taking after Tuesday's rally. LME tin is trading up over 1% on the day at $14,200/ton.
