© data: Bloomberg, Öko-Invest; gaphic: PHOTON International At first glance, the Amex Oil index seems to outperform the PPVX: The AMEX value has been standardized so that both curves start at the same level of 1,000 points on Aug. 1, 2001, when the PPVX was launched – and since then the solar index constantly has remained under the oil index. But solar grows faster than oil, and in the last one and a half years the gulf between the two curves has been narrowing.
