Korea's National Pension Put 219 Trillion Won into US Stocks — What Is a 13F Filing?
The National Pension Service filed a 13F with the SEC: 219 trillion won across 552 US stocks. Here's what a 13F is and how to read big-money moves as a beginner investor.
In Q2 2026, Korea's National Pension Service (NPS) submitted its 13F filing to the US Securities and Exchange Commission. The report shows the NPS holds 219 trillion won (roughly $150 billion) across 552 US stocks, having increased its positions in major Big Tech names like Apple and Microsoft as US markets climbed to record highs.
What Is a 13F?
A 13F is a quarterly filing required by the SEC from any institutional investor holding more than $100 million in US-listed equities. It must be submitted within 45 days of each quarter's end. The report reveals which stocks the institution holds and in what quantities—making it one of the few windows into big-money portfolios available to the public.
Why Does the NPS Hold So Much in US Stocks?
The NPS manages retirement savings for all Korean workers. Holding only Korean assets would leave the fund 100% exposed to won volatility and Korea's economic cycles—so international diversification is essential. US markets are the world's largest and most liquid, making them a natural destination for a significant allocation.
In 2026, the NPS's overseas equity allocation has reached record levels. The semiconductor boom and surging US markets have amplified the fund's mark-to-market gains significantly.
How Can You Use Institutional Filings in Your Own Investing?
The key limitation of a 13F is that it's a snapshot from up to 45 days ago. If the filing shows the NPS bought a lot of a particular stock, they may have already sold it by now. Blindly 'following' 13F buys has a timing problem built in.
