JAKARTA (Yosefardi) – The Indonesia Stock Exchange (IDX) will implement new lot rules for trading stocks by December 1, 2013, aiming to boost liquidity and increase retail investors’ participation.

Under new rules, one lot will only consist of just 100 shares, down from the current minimum of 500.

Currently many small retail investors feel burdened when they want to buy blue-chip stocks, for example, because they must buy a minimum 500 shares.

In attracting retail investors and boosting liquidity, IDX is also considering raising the minimum amount of shares released during an initial public offering from 10% to at least 15-20%.

As of August 13, 2013, IDX’s market capitalization reached US$446.8 billion, equivalent Rp4,237 trillion, the third largest in Asia region, behind Japan and China.
