KUALA LUMPUR, July 11 (Reuters) - Lotte Chemical Titan Holding Bhd started trading on the Malaysian stock exchange on Tuesday at 6.50 ringgit per share, unchanged from its IPO offer price.

The $878 million-listing was the largest initial public offering (IPO) in Malaysia since 2012.

Last week, the integrated petrochemical producer, part of South Korean conglomerate Lotte Group, had to cut the size of its offering due to lukewarm investor interest. The IPO was priced at the lower end of the indicative price range of 6.50-8.00 ringgit per share.
