Platinum prices have been able to extend yesterday's rebound and continue to gain ground this morning, although trading remains choppy and volatile going into the weekend. Positive market sentiment from recent US data may have helped to dampen market concern over the potential for Chinese economic slowing. However, some traders feel there may be too much residual risk concerns from an unresolved Greek debt situation for April platinum to climb all the way back towards last week's highs. A stronger than expected German PPI number this morning could provide an early indication of rising industrial platinum demand from German automakers later in the year.
