Indonesia stocks rebound 4.8 percent after exchange tightens index rules

Indonesia's Jakarta Composite rose 4.8 percent on Tuesday, recovering from a six-year closing low, after the stock exchange excluded stocks with highly concentrated shareholding from its benchmark and halved the daily down limit on share prices.

Why it matters: The rebound follows a fall of nearly 15 percent over two sessions after MSCI warned it may downgrade Indonesia from emerging-market to standalone status, a change that could force selling by passive funds, and Bloomberg reported questions remain over whether the exchange measures go far enough to answer MSCI's concerns.

Indonesia’s Jakarta Composite Index rose 4.8 percent on Tuesday, recovering from a six-year closing low, after the stock exchange on Monday excluded stocks with highly concentrated shareholding from its benchmark index and halved the daily down limit on share prices. The measures answer MSCI’s warning last week that it may downgrade Indonesia from emerging-market status to standalone status, which could trigger selling by passive funds that track global indexes; Indonesian equities fell nearly 15 percent over the two sessions after that warning, a two-day fall Bloomberg put as the steepest since 1989, leaving Indonesia the world’s worst-performing stock market this year even after Tuesday’s rebound. The rebound ran against the region, where MSCI’s emerging Asia gauge fell 1.4 percent on a 3.7 percent fall in South Korean equities.
