HNX ANNOUNCES CONSTITUENT STOCKS IN HNX 30 BASKET and OFFICIALLY LAUNCHES HNX 30 ON 09/07/2012

On 09/07/2012, Hanoi Stock Exchange will officially launch the new index HNX30. HNX 30 Index is the price index of TOP 30 stocks, acting as a premise for developing products on index. Base date of HNX30 Index is 03/01/2012 and base value is 100 points.

HNX 30 Index is calculated based on free float adjusted market capitalization in which shares are   subject to transfer restrictions as per the laws and voluntary restriction commitments. Holdings by State entities as a principal shareholder, shareholding related to registered trade marks and holdings by PDMRs and connected persons are considered restricted and excluded from HNX 30 Index calculation.

HNX 30 Index applies the cap ratio of 15%, the maximum rate of market value of a stock constituent in the index basket. The cap ratio is used to decrease the influence of large capitalization constituents on the index.

Stock constituents are selected with consideration of liquidity, capitalization and the number of stocks in the same industry (the number of stocks in each industry does not exceed 20% number of stocks in the basket).  The HNX applies the Hanoi Standard Industrial Classification (HaSIC), which is based on ISIC v.4, to classify listed companies.

The index basket is reviewed every 6 months. 25 stocks with biggest free float adjusted market capitalization will be selected from current 30 constituents, and the remaining 5 stocks are selected according to the maintenance principles.

HNX 30 Index is provided in real-time basis. News relating to periodical adjustments (constituents, free float, cap ratio, outstanding shares) will be announced at least 7 working days before the effective date. Special adjustments will be announced at least 1 day before the effective date.
