The world’s largest listed jeweler, Chow Tai Fook (1929.HKG), suffered a sharp first-half sales drop this year compared to last, The Financial Times reported. The group announced on Tuesday that revenue and pre-tax profit for the six months to September 30 fell almost a quarter year-on-year. Chow Tai Fook draws more than half its revenue from China, but said it remains unworried by the current economic slowdown there. Citing high sales last year because of declining gold prices as a major factor, the group said it remained committed to the Chinese market and has high hopes for a new generation of young professional women who want to spend money on jewelry for themselves.
