Analysts fear Asia's blue chips will be hit hardest after benchmark stock weighting is altered
A move by Morgan Stanley Capital International (MSCI) to change its Emerging Market Free Stock indices to a free float could send prices of local blue chips into a tailspin in the week ahead.
MSCI is expected to alter its stock market portfolio today by using the calculation method of a free float. Stocks are presently weighted on the basis of market capitalisation.
A free-float system would weight stocks according to the number of shares actually available for open trade, rather than according to the stakes held by governments or non-listed companies. MSCI and FTSE International are the most widely used benchmarks for international equity investment, with FTSE already using a free-float system.
It is the first time that MSCI has considered such a dramatic change, and analysts have voiced concern over the effects such a system could have on the Hang Seng Index.
Alan Hutcheson, an analyst at Pacific Challenge Securities, expects Hong Kong to suffer more than some other Asian markets.
'The Hong Kong market free float is 50 per cent, which is a lot lower that other big developed markets,' Mr Hutcheson said.
