PurePlay^tm Indicies

Camino has developed several PurePlay^tm Indices to aid in tracking aggregate performance of selected Sustainable Energy Businesses that are pursuing specific business activities. We use an equal weight method (EW) as described in Standard & Poor's Index Mathematics Methodology, July 2006. We also compute a modified market capitalization (MMC) index for Solar PV consistent with the method described in Standard & Poor's Clean Energy Index Methodology, August 2007. The equal indices are calculated from daily closing prices, rebalanced semi-annually, and re-normed after the rebalance to maintain index continuity. The MMC index is calculated from daily closing prices, rebalanced quarterly, and re-normed after the rebalance to maintain index continuity.
