While platinum prices posted a fresh new high for the move overnight and prices continue to find carryover support from gains in gold and silver, some traders feel that platinum prices may be overextended after a three-week rally of almost $200 an ounce. Like gold and silver, platinum is seeing a gradual improvement in macro economic psychology as fear seems to be declining towards the Euro zone's debt problems. While Anglo American platinum overnight saw a decline in 2011 earnings, that result was supposedly the result of a one-off accounting charge and not a sign of either production or demand issues. Impala Platinum saw its CEO step down overnight, which may be a sign that platinum producers are seeing adversity at the corporate level and might suggest any dramatic expansion of production ahead might be difficult at best.
