Chow Tai Fook group is a Hong Kong–based, privately owned conglomerate with holdings in the jewellery, property development, hotel, department store, transportation, energy, telecommunications, port, casino, and other businesses. Despite the holding companies of the group, namely Chow Tai Fook Capital Limited, Chow Tai Fook Limited, Chow Tai Fook Enterprises Limited, etc. being privately owned, the group has been partially listed on the stock market via associate company New World Development and subsidiary Chow Tai Fook Jewellery Group Limited. As of 31 December 2018, New World Development was ranked as the 47th-largest company by market capitalization on the Stock Exchange of Hong Kong, which was HK$105.68061 billion. However, the size of the unlisted portions of the Chow Tai Fook business empire is unclear. The Financial Times quoted one banker of the Cheng Yu-tung family, who said, "You can't look at [Cheng] YT without looking at the private side of the business and his ability to spot early investment opportunities".
