From The Weekender

Success isn’t at the top of the corporate ladder anymore

My generation watched our parents give everything to a company. We decided to give it to ourselves instead. But it's more complicated than that.

Read on The Weekender

MSCI announced its rebalancing review on the evening of May 12, with changes in constituents for its Global Standard Indexes set to take place after the stock market closes on May 29, and become effective on June 1.

In its latest review, MSCI added no Indonesian stocks but removed PT Barito Renewables Energy, PT Chandra Asri Pacific and PT Petrindo Jaya Kreasi, all affiliated with local conglomerate Barito Pacific, as well as PT Amman Mineral International and Dian Swastika Sentosa, the mining arm of Sinar Mas Group.

MSCI also downgraded consumer goods retailer PT Sumber Alfaria Trijaya to its Global Small Cap Index, from which it removed 13 Indonesian stocks altogether.
