Oct. 5 - The S&P GSCI increased a slight 0.17% in September, led by the S&P GSCI Precious Metals Index gain of 6.5%.
Year-to-date, the S&P GSCI ended the month with a 4.7% gain, despite the indexs 1.8% decline for Q3. The S&P GSCI Industrial Metals Index has been the sector leader in 2009 and has remained in the lead, posting a YTD gain of 56.8% on the back of a 20.7% increase in Q3. In addition to the mean reversion factor from 2008 and plenty of demand from China in the industrial metals, many analysts have suggested that a key factor contributing to the popularity of the easy to store metals is the low opportunity cost demand of dollar-based metal investing, due to extremely low base rates.
