Jakarta (ANTARA News) - Disappointed investors increased the Indonesian joint composite index (JCI) amid regional exchanges.

"Investors are disappointed about French and German officials meeting which failed to form a joint bond (Eurobond) as a measure to take liquidity to the European zone," said Indosurya Asset Management analyst Adha Mubarak here, Thursday.

The JCI was opened stronger with 11.73 points or 0.3 percent to 3,965.01. The LQ45 index also increases 2.91 points or 0.42 percent to 703.32 points.

Earlier, French president Nicolas Sarkozy and German chancellor Angela Merkel met to discuss countering the crisis by establishing the Eurobond,

Several considered low price domestic stocks also encouraged market players to enter and raise the Indonesian Stock Exchange (IDX) index.

Adha said that investors are also expected to be aware of external negative sentiments because the IDX index is following external share flows.

Unpleasant British economy data will bring a negative impact on the European stock market and cause an impact on Asian regional stock markets, he said.

Developing countries in Asia can retain the index decline deeper, including Indonesia with its positive economic fundamentals, Adha said.

Meanwhile regional exchanges such as the Hang Seng Index fell 60.52 points (0.30 percent) to 20,228.51 level, the Nikkei-225 index fell 37.74 points (0.42 percent) to 9019.52 level, and the Straits Times gained 8.85 points (0.31 percent) to 2837.38 level.
