Freeport-McMoRan ( FCX ) shares, among other metal and mining stocks, are moving higher Tuesday after China Central Bank announced a new stimulus package.

What Happened: The stimulus package includes cutting the reserve requirement ratio (RRR) by .5 percentage points and lowering both the loan prime rate and deposit rates by 0.2 to 0.25 percentage points.

In addition, the central bank cut the seven-day reverse repurchase rate to 1.5% and lowered the minimum down-payment ratio to 15%. The announcement of these economic measures comes amid a slowdown in China’s markets and could help support investment and support metals demand.

Larry Hu, head of China economics at Macquarie Group Limited, told Bloomberg, "The purpose of today's briefing is to inject confidence into the market, judging by the fact that the authorities revealed measures in one go. The stimulus push will still need coordination from other policies — particularly follow-up policies from the fiscal side.”

Other copper related stocks that are trading higher following the bank’s announcement include Hudbay Minerals Inc ( HBM ) and Rio Tinto Plc ( RIO ) .
