Fewer Hong Kong investors (36%) are more confident about investment opportunities in 2015, compared to the number of optimistic investors from last year's (45%) survey, the Schroders Global Investment Trend Survey 2015 reveals.

Expectations on risk/reward are modest with 72% of the 500 Hong Kong residents surveyed plan to invest in low and medium risk assets, and 93% of all respondents expect to make a profit with an overall return of about 8%, which may not be easy to achieve given choppy markets and low, patchy growth around the world, British fund manager Schroders says.

Hong Kong is the only market amongst the nine Asia markets surveyed that expect a single digit return on their investment this year. Part of the reason for this could be that 88% of the respondents only achieved an average 7% investment return last year, which was one of the lowest in the region.

Despite this, 80% of Hong Kong investors said they will continue to rely on their own judgement to make investment decisions, and of whom 44% will change their investment strategy in response to current market conditions while 36% plan to invest in broadly the same asset classes as previous years. Only 16% said they would seek professional investment advice.

Asia remains the most favoured investment region among Hong Kong investors, as 75% of them think it will deliver the best returns this year, 3% less than in 2014. North American is the second most favoured region, with more than 31% of investors think it will perform well, 4% more than last year.

While only 21% of Hong Kong investors prefer to invest in Europe, Schroders believes the recent strong economic data and corporate earnings shows this region may be the better investment opportunity. The drop in oil prices, weaker euro and lower funding costs are key factors that will potentially help Eurozone corporates achieve double-digit earnings growth in 2015.

"Whilst some Hong Kong investors may have made a small fortune from the Hong Kong stock market rally in April, the rally was not supported by any fundamentals and we are already seeing the affects of this. There have been more peaks and troughs in the market, and frequent news reports of huge investment losses from speculative bets. As such, investors may consider using professional advice to help them diversify investment risks and generate potential sustainable, long-term returns," Grace Ho, head of marketing, Asia, Schroders.

In fact, Hong Kong investors are thinking more long-term and are realising the importance of sustainable income, and this is where professional investment advice can provide value.

Nearly all (94%) survey respondents said they plan to invest in assets that generate a regular income. The top five reasons for this are bank interest rates are too low (38%), long-term re-investment strategy (32%), preference for dividend paying companies over growth investing (29%), rising cost of living (26%), and economic and political instability (24%).

Volatility of markets since the financial crisis may have influenced investors' search for income. The Schroders survey showed that 26% of Hong Kong investors plan to invest directly in stocks while a total of 34% plan to invest in multi asset funds, equity funds and bond funds to generate regular income in the next 12 months.

It also revealed that 33% of Hong Kong investors plan to use the income generated to supplement their salary, 29% will reinvest the income to further grow their investment portfolio, and 14% will contribute the income to their retirement savings.

A total of 500 retail investors in Hong Kong participated in the survey, with a near equal split between male and female. The average age of the Hong Kong respondents was 37 years old.
