IDX closed at 6,221.01 on Thursday evening, increasing 39.83 percent, or 0.64 percent higher than the opening at 6,192.27.
The 45 prime bonds "LQ45" strengthened by 6.53 points, or 0.66 percent, to 990.87.
"Our economic stability remains under control, despite some aspects that need correction, such as our current deficit account," noted Bahana Securities analyst Muhammad Wafi here on Thursday.
The bullish move of IDX was also supported by foreign investors' buying actions that closed a total Rp188.27 billion of foreign net buy today.
Thus, Wafi hopes that current domestic economy would continue to remain stable amid sluggish global economy's projection that had been overshadowed by US-China's trade war.
"The trade war still becomes an external negative sentiment," he added.
