South Korean cosmetics stocks rise as K-content index falls through October 8

South Korean cosmetics shares rose sharply in 2026 while the KRX K-Content index fell through October 8, according to Korea Exchange figures reported by Yonhap in Seoul on October 9. The split matters because the two groups have moved in opposite directions despite their association with Korean products and culture: a consumer staples index that includes cosmetics gained 17.29%, while the K-content index lost 31.37%.

The figures cover the year through Thursday, October 8. They describe share prices and index performance, rather than sales or profits. Yonhap reported that the K-content decline was the largest among KRX industry indexes and that 17 of its 19 constituent stocks had fallen.

Which cosmetics and K-content shares moved

Among cosmetics companies, Kolmar Korea shares rose 120.77% over the period, more than doubling. Cosmax gained 88.04% and APR rose 60.82%, according to the detailed Yonhap report carried by Korea Economic TV. The broader KRX Consumer Staples index includes food companies as well as cosmetics makers, so its 17.29% rise should not be read as the return of a cosmetics-only index.

On the other side, Hybe shares fell 50.33%, Kakao declined 46.26% and JYP Entertainment lost 45.52%. The fuller Yonhap account also recorded declines of 44.47% for SOOP, 44.04% for CJ ENM and 42.59% for SM Entertainment. These are individual stock moves over the reported period, not measures of how much their businesses grew or contracted.

Yonhap's fuller report also put the falls in the entertainment and culture industry indexes of the Kospi and Kosdaq markets at 42.88% and 43.62%, respectively, through October 8. It described each as the largest decline among industry indexes in its market. Those measures give another view of the breadth of the sell-off, although they are separate from the 19-stock KRX K-Content index.

How analysts explain the K-content decline

Kiwoom Securities analyst Lim Soo-jin told Yonhap that valuation premiums for entertainment stocks had narrowed as investors compared the sector's growth with much stronger semiconductor growth. Lim also cited concern about whether entertainment companies had enough new intellectual property to follow their existing acts and other properties. That is an analyst's explanation for investor sentiment, not a finding that every company lacks future projects.

IBK Investment & Securities research head Lee Seung-hoon said hardware stocks had outperformed software stocks this year. He cited a shortage of clear gaming hits in the first half as one reason for weak game shares, while identifying Pearl Abyss's Crimson Desert as a successful release this year. Lee said the performance of individual new games could alter the direction of game stocks, a qualification to any explanation applied to the whole sector.

The report also cited an October 8 note from NH Investment & Securities analyst Lee Hwa-jung, who said doubts about the durability of large revenues and improvements in profitability had weighed on valuations even when entertainment companies reported strong results. Samsung Securities analyst Oh Dong-hwan raised distinct concerns about platform companies: Naver's search share as AI agents expand, Kakao's advertising profitability, uncertainty about customers for Naver's AI infrastructure plans, and Kakao's planned corporate split. These assessments concern different companies and should not be treated as a single established cause of the index decline.

What record cosmetics exports show

A separate Ministry of Trade, Industry and Resources release provides business context for cosmetics. It said South Korean cosmetics exports reached a record $1.51 billion in September, up 31.4% from a year earlier, with shipments rising to China, the United States, ASEAN and the European Union. That is a monthly national export total; it does not identify the earnings of Kolmar Korea, Cosmax or APR, or establish that exports caused their shares to rise.

The ministry reported total September exports of $120.94 billion, an 83.5% annual increase. Semiconductor exports reached $60.30 billion, up 262.8%. Those figures provide context for analysts' comparisons with the semiconductor sector, but the export release does not test their account of stock valuations. The next test for investors will be company results and subsequent market trading; neither the reported index figures nor the September export record establishes what those results or share prices will be.
