Prices are being driven up by hedge funds, which are buying platinum because its fundamentals are looking good. Platinum has been in deficit for the past six years, and it's expected it will be in deficit this year.
Given the way the market has been trading over the past few days, we are very likely to see prices testing another 25-year high again this week.
There is no market-specific impetus for fresh long positions to be established at present. Sentiment has been weakened by weakness across commodities over the past few days and the dollar is holding up well.
