South Korea’s top 10 conglomerates saw their stock market cap sink 5.32 percent this year, as most affiliated firms suffered a decline in their share prices amid a bearish run on the local stock market, data showed on Monday.

The combined market capitalization of affiliates under their wings stood at 693.86 trillion won ($653 billion) as of Wednesday, compared with 732.84 trillion won at the end of last year, according to the data compiled by the Korea Exchange.

The decline was largely attributed to a slump in Samsung Electronics Co., the country’s top market cap, and other major companies.

During the cited period, the country’s key stock index, the KOSPI, slumped to 1,935.84 points from 2,011.34 points.

According to the data, Hyundai Heavy Industries Group, the country’s leading shipbuilding conglomerate, suffered the largest fall of 15.4 percent in its market cap to 20.29 trillion won as of Wednesday, followed by energy and retail giant GS Group with a 10.07 percent dip to 10.39 trillion won.
