Which Korean stocks did the National Pension Service (NPS) report larger or smaller stakes in over the past month? Among the 138 companies with relevant disclosures filed from September 20 through October 20, 2026, stakes rose in 66, fell in 69, and were unchanged in three. Several construction-related companies increased, while large decreases appeared among PCB and smartphone component suppliers.
Here, “NPS rebalancing” means changes in disclosed ownership percentages for individual companies. It is not an industry-wide measure of net buying or selling. The tables select companies with large changes or shared industry patterns; they are grouped by industry, not ranked across all companies. Counterexamples appear below.
Stakes that increased: selected construction and insurance companies
| Related industry or theme | Company | Before → after stake | Net change |
|---|---|---|---|
| Construction | GS E&C | 7.82% → 12.88% | +5.06 pp |
| Construction and housing | Xi S&D | 4.67% → 7.37% | +2.70 pp |
| Construction | IPARK Hyundai Development Company | 10.40% → 12.02% | +1.62 pp |
| Insurance | Hyundai Marine & Fire Insurance | 9.42% → 12.37% | +2.95 pp |
| Food | Binggrae | 6.09% → 9.37% | +3.28 pp |
Of the six disclosed companies classified as construction in this article, five showed increases. Hyundai Engineering & Construction (+0.36 pp) and DL E&C (+0.80 pp) joined the three in the table, while IS Dongseo fell 1.19 pp. GS E&C had the largest increase among these six. This grouping follows company businesses: it includes Xi S&D and excludes the holding company DL (+1.14 pp), so it differs from the site’s “Construction” theme membership.
Stakes rose in all five insurance companies in this grouping, but the increases varied. Hyundai Marine & Fire Insurance (+2.95 pp) stood out, followed by DB Insurance (+1.03 pp) and Hanwha Life Insurance (+1.06 pp). Hanwha General Insurance (+0.10 pp) and Mirae Asset Life Insurance (+0.01 pp) changed little.
Binggrae (+3.28 pp) was another large increase, but one company cannot represent the whole food industry.
Stakes that decreased: PCB and smartphone components, travel, and retail
| Related industry or theme | Company | Before → after stake | Net change |
|---|---|---|---|
| PCB and smartphone components | BH | 13.32% → 9.99% | −3.33 pp |
| PCB and package substrates | Korea Circuit | 9.67% → 6.55% | −3.12 pp |
| Camera modules and smartphone components | LG Innotek | 10.54% → 7.44% | −3.10 pp |
| Package substrates | Daeduck Electronics | 12.76% → 9.67% | −3.09 pp |
| Travel and leisure | Paradise | 11.37% → 8.39% | −2.98 pp |
| Travel and leisure | Lotte Tour Development | 10.47% → 7.80% | −2.67 pp |
| Department stores and retail | Hyundai Department Store | 12.99% → 10.31% | −2.68 pp |
BH, Korea Circuit, LG Innotek, Daeduck Electronics, and Haesung DS (−2.11 pp) all declined. The decreases clustered around PCB, substrates, and smartphone suppliers, but Simmtech rose 1.05 pp and Isu Petasys rose 0.08 pp.
Among casino and duty-free-related travel names, Hotel Shilla (−0.93 pp) and Global Tax Free (−2.32 pp) also fell. But GS P&L (+1.07 pp) and JS Corporation (+1.04 pp), both in the site’s “Hotel/Resort” theme, rose. In retail, Shinsegae (−1.36 pp) and Lotte Shopping (−1.56 pp) joined Hyundai Department Store, while BGF Retail rose 1.00 pp. The table is grouped by industry, not sorted by decline. Across all companies reviewed, CJ had the largest decrease at −3.41 pp.
Did cosmetics and construction all move in one direction?
The cosmetics and beauty-related companies were mixed. PharmaResearch (+2.73 pp), LG Household & Health Care (+2.30 pp), Amorepacific (+1.48 pp), and Cosmax (+0.36 pp) rose, while Cosmecca Korea (−2.07 pp), d’Alba Global (−1.08 pp), and Kolmar Korea (−0.68 pp) fell. PharmaResearch's increase was substantial, but the falling companies matter too. IS Dongseo was also an exception among the construction companies. These disclosures do not establish an industry-wide allocation change.
How should you read the NPS disclosures?
This article covers 172 NPS stake disclosures filed from September 20 through October 20, 2026. Of those, 118 were filed on October 2 and 34 on October 6; only 11 were filed from October 12 onward. “Past month” therefore does not mean changes occurred evenly across the month. Large-shareholding reports were concentrated on October 2.
For each company, we compare the starting and latest reported ownership percentages within the period. We do not add individual filing change fields or count a restatement of all holdings as a fresh purchase. Industry and theme groupings are descriptive and based on 10Bagger's theme membership data and company businesses.
A filing date may differ from the trade date. Ownership changes alone do not reveal transaction amounts or motives. Only disclosed companies appear, and some filings may be absent from the source data because of the DART detail API's structure. These figures are not an industry-wide flow measure. Explore individual filings on the 10Bagger NPS disclosures page. Its one-month filter moves forward with the latest filing date, so future screen figures may differ from this article's fixed period. The Financial Supervisory Service's disclosure guide explains the reporting rules.
