In light of the market interest to invest in energy shares in Israel after the Tamar natural gas discovery, a new company – E-Trader – was established on 17.8.09 to deal in digital options for a new energy index. The index will be calculated on a daily basis and will be offered to the public as call or put options on the index with daily trading options on Israeli energy shares. The index is the weighted average value of seven leading energy shares in Israel with special emphasis on oil and gas exploration companies: Isramco, Delek Energy, Delek Drilling, Avner, Naphtha, Delek Israel and Dor Alon. The index that was launched by E-Trader enables investors to invest in energy companies through the purchase of options in one of the most volatile markets of the Tel Aviv Stock Exchange.
