Burberry warns fall in HK sales could impact its full-year margin

British luxury brand Burberry warned on Wednesday that a fall in sales in the key market of Hong Kong in the last quarter of 2014 could impact its full-year margin. Pro-democracy protests began choking parts of the Asia financial center in late September, disrupting business in one of the world’s top markets for luxury companies, which accounts for about USD9.7 billion of global luxury sales, or 4 percent of the total, according to estimates by Bernstein Research.
