"This year is going to be tough, probably the toughest year for many foreign luxury brands since they entered into China," he said.
"Sales of jewellery and valuable watches during Chinese New Year were quite disappointing," said Caroline Mak of the Hong Kong Retail Management Association. "Sales growth of over 30 per cent last year is unsustainable against a worsening macro-economic backdrop."
Some member jewellers reported customers buying smaller diamonds than they used to, she said.
Hong Kong jeweller Chow Sang Sang Holdings International, whose sales grew as much as 28 per cent in the first three days of the holiday, expects quarterly sales growth to slow to 10 per cent in the second quarter from 15 per cent in the first.
Sales director Dennis Lau wouldn't make projections for the year because of worries a further global downturn could hurt consumer sentiment.
"We can't see how strong the recovery in the US is, and the debt crisis in Europe never seems to end," Lau said. "If those economies mess things again, it could severely hurt global consumer confidence."
Twinky Choi, an assistant at a Hong Kong Shiseido cosmetics store, is seeing that first-hand. "People are browsing," Choi said. "They don't buy instantly, unlike last year when customers were grabbing everything."
China's economic growth, hurt by a property market slump and slower export growth, is poised to weaken to 8.5 per cent this year from about 9.2 per cent in 2011, the median estimate of economists surveyed shows.
"The momentum is not exciting," noted Macquarie Capital Securities analyst Linda Huang.
The Lunar holiday, like Thanksgiving or Christmas in the United States, is among the biggest selling periods in China. Chinese consumers spend more at home and at overseas holiday spots such as Hong Kong and Macau. This year's holiday extended from January 23 to 29 and marked the start of the year of the dragon.
"It does give some indications on retail sentiment," said Phoebe Tse, an analyst at Barclays Capital Asia. "It is one of the busiest shopping seasons."
Lipstick and fragrance seller Sa Sa International Holdings said Lunar sales were below its forecasts. The retailer's Hong Kong and Macau sales rose 17 per cent during the Lunar holiday - "slightly below our expectations", said chief executive Simon Kwok. "Looking ahead, the group remains cautiously optimistic."
Mak said her association expected Hong Kong retail sales growth to slow to 15 per cent this year from 25 per cent last year.
China's consumers have been hurt by a drop in home prices, which fell for a fifth month in January, according to SouFun Holdings, the nation's biggest real-estate website owner. Residential prices slid in 60 of 100 cities tracked by the company last month. The benchmark Shanghai Stock Exchange Composite Index has also fallen 17 per cent over the past year, lowering the value of consumers' investments.
"Macro-economic uncertainties impact consumer confidence," Tse said. "They feel more secure when they have money in the pocket."
Chinese tourists on holiday drove up January casino revenue in the gambling centre of Macau 35 per cent to 25 billion patacas ($3.6 billion). Even so, high-stakes gamblers, who bring in the most revenue and can bet as much as $300,600 a hand, may not have boosted sales as much as previous years because of less available credit, says BOC International analyst Edwin Fan.
Banks have less money to lend because China's policy makers have raised interest rates and reserve ratio requirements.
Macau casino revenue growth could slow to 22 per cent this year from 42 per cent a year ago, said Victor Yip, an analyst at UOB Kay Hian.
At South Korean retailer Shinsegae sales rose 9 per cent between January 6 and 17, a promotional period just before the new year for tourists. That was slower than last year's 16 per cent, said spokeswoman Lee Jung Ah.
At Korea's Lotte Shopping sales growth in a promotional period from January 6 to 19 was 9.8 per cent this year compared with last year's holiday increase of 16 per cent.
Expenditure per customer at Tokyo's VenusFort mall didn't rise and wasn't proportional to the rise in Chinese visitors, probably because of the stronger Japanese yen, said spokesman Yusuke Nishimura.
Hong Kong jeweller Luk Fook Holdings International said sales at stores open at least a year grew 13 per cent in mainland China and 4 per cent in Hong Kong and Macau during the week-long holiday. That was below expectations as "a seasonal surge failed to materialise" for the industry, according to Citigroup Global Markets.
"The sales of jewellery and valuable watches are good indicators of how strong the Chinese tourists' purchasing power is," said Mak.
"We expect some Chinese shoppers to cut back on big-ticket items as the wealth effect fades."
