These three risks apply here too especially the earnings and valuation risks. Note that they are not the same.
As to political risk, the risk here is not in Singapore but in Malaysia and Indonesia.
If religious tensions escalate; or the Malaysian government cracks down on dissidents or is seen as weak, then foreigners will sell their Malaysian shares, and S’pore will be caught in the backwash.
In Indonesia the issues are the corruption and the unhappiness about it. Thousands of demonstrators have taken part in anti-government protests. Protesters say President Susilo Bambang Yudhoyono has not delivered on his promise to eradicate corruption during the first 100 days of his second term.
These issues could affect the perception of investors about Indonesia (a darling of emerging market investors), again causing spillover effects here.
