Investors should start taking profits if the Hang Seng Index breaches the 12,600-point level but retain an overweight position in Hong Kong, according to HSBC Securities.
'Beyond 12,600 we have been recommending to clients it's time to cash in a little bit - the market has almost doubled from the low [in August last year], it's time to enjoy ourselves,' regional strategist Abhijit Chakrabortti said.
HSBC Securities recommends 43 per cent of regional exposure should be in Hong Kong equities.
The profit-taking advice follows strong gains since last month, with the blue-chip index surging past levels predicted for the year-end by market bulls.
A continued flow of funds into Hong Kong still justified a positive outlook on the stock market, especially as the market was also under-owned relative to the amount of money in the economy, Mr Chakrabortti said.
'The next wave of liquidity will come from the global funds to Asia,' Mr Chakrabortti said.
