BANGKOK, Oct 18 (Reuters) - Most Southeast Asian stocks edged higher on Friday, poised for modest gains on the week, as investors piled into regional large caps after strong quarterly results, with solid Chinese data supporting sentiment across Asian stock markets. Singapore-listed Keppel Corp, the builder of offshore oil rigs, rose about 1 percent after it posted a 32 percent rise in third-quarter net profit. The key Straits Times Index edged up 0.3 percent, on track for a weekly gain of 0.6 percent, building on a 1.3 percent rise on the previous week. Stocks in Thailand and the Philippines outperformed, with Thai SET index gaining 0.9 percent at midday and the Philippine main index adding 0.6 percent, both climbing around 1.7 percent week to date. Shares in Bangkok Bank jumped 2.5 percent after Thailand's largest lender by assets reported a 21 percent rise in quarterly net profit, beating estimates. Philippine conglomerate San Miguel Corp were the top percentage gainer on the Philippine benchmark index, up 5.2 percent, after a report that the conglomerate is set to distribute shares in its controlling shareholder Top Frontier Investment Holdings Inc. Indonesia was among weak spot, with Jakarta's composite index drifting slightly into negative territory, led by losses in the biggest firm Astra International due to weak outlook of auto sales next year. Shares in coal miners, including Adaro Energy and Harum Energy, bucked the trend, with brokers citing a report involving stricter regulation on Chinese coal mines that could contract world coal supply. "It appears that sentiment wise, this news has provided some positive share price boost towards the Indonesian listed coal companies," broker Bahana Securities said in a report. The benchmark Indonesian index is set to end the week 0.2 percent lower.
