Every quarter, South Korea’s National Pension Fund and legendary investors like Warren Buffett file their stock holdings with regulators. This data is public — but it’s scattered across three different disclosure systems, making it impossible for individual investors to track what’s actually being bought and sold.
I built WhaleLens because I was tired of manually hunting through government databases to answer simple questions: What did the National Pension Fund just buy? How much did Buffett increase his position this quarter? Which stocks are multiple mega-investors holding at the same time?
What It Does
- Real-time National Pension Fund filings. When South Korea’s pension fund crosses the 5% ownership threshold on a stock, it triggers a mandatory disclosure. WhaleLens automatically collects these filings and shows you the stock name, the change in shareholding percentage, and the actual number of shares bought or sold — breaking down the pension fund’s true activity every single day.
- Complete pension fund portfolio visibility. See the fund’s top 200 domestic holdings with their portfolio weights, the exact stake in each company, and year-over-year changes. Each stock gets its own detail page showing the fund’s shareholding trend as a chart going back years.
- 13F tracking for legendary investors. Monitor 10 of the world’s most influential portfolio managers — Buffett, Cathie Wood, Ray Dalio, Bill Ackman, Michael Burry, and others — every quarter. See what they added, trimmed, newly bought, or liquidated entirely.
- Smart money consensus analysis. Overlap the holdings of all 11 mega-institutions tracked in the app. Which stocks do eight institutions own together? Which are held by just one? This consensus ranking reveals where the biggest capital is genuinely aligned.
- Telegram alerts. New filings drop as soon as they’re published. Subscribe to get instant notifications without opening the app.
Data updates hourly for new pension fund disclosures, daily for US 13F filings, and on the National Pension Service’s public data schedule for top holdings. Every number comes directly from South Korea’s Financial Supervisory Service DART system, the US SEC EDGAR database, and official government data portals — no guessing, no aggregation errors.
