Stocks remained stalled out near 725 for a fourth day on Tuesday after the index inched lower by less than a tenth of a percent. Combined trading volume in HCMC and Hanoi jumped to USD309 million, the highest ever. PLX (+4.9%) jumped to its highest level since listing last month after Nghi Son refinery announced that it delayed commercial production from Q3 2017 to early next year. This seems to be a move cheered by investors amid concerns PLX may not get good prices from that refinery.
