Energy stocks were once again the strongest performing sector as oil prices rose, with Brent crude touching US$50 per bbl. The wider fundamentals supporting the alternative energy sector strengthened during the month. Firstly, the Kyoto Protocol entered into force on 16 February. Although not a signatory, the US agreed to cooperate with Germany in the development of less polluting technology and joint action to make energy producers more efficient. In addition, following President Bush's speech in January urging Congress to pass the long-delayed Energy Bill, and his pledge for "strong funding for leading-edge technology", the fiscal 2006 Budget saw an increase in the Department of Energy's Fuel Cell and Hydrogen programs, and an initiative to support the development of crystalline silicon PV technology. In other areas, private equity firm Kelso & Co made an offer for Insurance Auto Auctions Inc. in the US auto recycling/salvage sector, which has a similar business model to Universal Salvage in the UK. In the US, the strongest performers during the month included Itron (meters & utilities software), which rose 17.3% on signs that utility spending in the US is strengthening and ongoing integration of the Schlumberger metering business. Fuel Cell Energy increased by 18.4% after announcing a joint venture with Alliance Power to supply clean energy to the Starwood Hotels & Resorts. In Japan, Horiba (environmental testing & monitoring) rose 19.5% on the back of better than expected results and an improved earnings outlook. The best performer in UK was Straight plc (recycling containers, UK), which rose 27% following the completion of the acquisition of its main competitor. On the downside, Tomra (reverse vending machines, Norway) fell 25.7% on disappointing sales and a poor outlook for 2005, while Stericycle (medical waste recycling, US) was down 11.9% on concern about competition after Waste Management International announced that it intended to expand recycling operations into clinical waste. During the month, we have increased our exposure to Pentair (water treatment, US), Active Power (flywheels, US) and Xantrex (power electronics, Canada) and taken profits in Horiba, Straight plc and Itron.
