The April platinum contract enters this morning's trading in close proximity to yesterday's high, which has been the highest price level since September 22nd of last year. In addition to finding carryover support from gold and silver prices, the platinum market has been strengthened by fears of more supply losses from the strike at the Impala Rustenburg mine. In fact, news reports are suggesting that these labor problems might spread to other mines and other companies, which many traders feel may have magnified the supply-side impact on prices.
