The local stock market opened higher on a rebound in oil prices. The index touched a high of 2,390.70 shortly before closing, marking its highest intra-day level in history.

Some analysts said the local stock market could test the 2,500-point level in the coming months.

Chi Ki-ho, head of the research division at Cape Investment & Securities, said the local stock market is expected to extend its winning streak to a seventh consecutive month of gains.

However, Chi said the local stock market has not shown signs of overheating as the rally is supported by expectations about healthier corporate earnings.
