SHANGHAI, Feb. 4 (SMM) – The 1304 SHFE lead contract price gapped nearly RMB 100/mt higher at RMB 15,600/mt on Monday due to the positive US economic data released last Friday and the lower US dollar index. Some investors booked profits later, driving SHFE lead prices to edge down, but prices returned to RMB 15,520-15,570/mt due to strong LME lead prices and rising domestic stocks and finally ended at RMB 15,535/mt. Trading volumes increased 174 lots to 336 lots, while positions were up 112 lots to 2,418 lots.
