JPMorgan filed on Oct. 20-22 that it holds more than 5% of three Korean chip materials, parts and equipment companies and one electronic-components maker. The stakes are New Power Plasma 5.37%, EXICON 5.39%, Nepes Ark 5.08% and Samwha Capacitor 5.08%. Korea Economic Daily put the value of JPMorgan's stakes in the four companies at about KRW 140 billion (about $106 million) at the Oct. 23 close.
The common reading is 'a big foreign investor picked a promising stock'. But the key is one box in the filing: the purpose of the holding. In all four filings it was 'passive investment'. This filing is not a recommendation to buy. It is a notice that says, here is how much we hold right now.
- What does a 5% filing report?
Article 147 of the Capital Markets Act says that when a person, together with related parties (people counted together with them, such as family members and affiliates), comes to hold 5% or more of a listed company's total issued shares, they must report the holding and its purpose to the Financial Services Commission and the stock exchange within 5 days. Days such as holidays are not counted, and this is commonly called the '5% rule'.
After that, they must report again within 5 days of the day the holding changes by 1% or more, and within 5 days if the purpose of the holding changes. However, the law lets a presidential decree (the enforcement decree) set the content and timing of reports differently for holdings that are not meant to influence management. That means a passive investor's next report may come on a schedule different from the 5-day rule.
Think of how a property register records that a house has a new owner. But a register only tells you who owns it, while a 5% filing also makes the holder write down why they hold it.
- How do the three purpose boxes differ?
The text of the law asks only whether the purpose is 'to influence the company's management'. Aju Business Daily explains this as three kinds: influencing management (taking part in management), general investment and passive investment. A holder who reports taking part in management must also disclose a concrete plan for doing so, and general investment covers active use of shareholder rights, such as pushing for higher dividends or raising questions about executive pay.
Passive investment, as the enforcement decree defines it, means using only the rights the law guarantees to every shareholder, such as voting rights, the right to subscribe for new shares and the right to receive dividends. It is closer to a notice that the holder will not speak up on how the company is run.
- What do JPMorgan's four filings tell us?
According to Korea Economic Daily, the purpose in all four filings is passive investment. JPMorgan did not say it will give opinions on how these companies are run. It reported that it holds the shares while using only a shareholder's basic rights.
The roughly KRW 140 billion (about $106 million) is not the market value of the four companies. It is the value of the stakes JPMorgan holds. Put simply, a lot of money did go in, but the purpose box says there is nothing it asks of the companies.
- Why does a big investor's buying filing read like a signal to buy?
Aju Business Daily noted that even a filing with a passive-investment purpose is sometimes read by the market as an investment signal and the share price rises. Korea Economic Daily also read the four picks as companies expected to see operating profit rise sharply this year.
Both are the press's interpretation. It is like hearing that a professional reseller bought several of an item on a used-goods app and guessing the price will go up. But a 5% filing states whether the holder aims to influence management, not the reason for buying, and it does not say when the holder will sell.
- What should we watch after the first filing?
A 5% filing is a record of the holding at one point in time, not a promise to keep holding. So what shows the big investor's actual moves is whether a new report appears after the holding changes by 1% or more of the issued shares.
But as seen above, reports on holdings such as passive investments can be set on a different schedule by the enforcement decree, so the time it takes for a report to appear after a change can differ from the 5-day rule.
- BITPRESS Insight
Retail investors who see a big investor's 5% filing can easily take it to mean 'that company will rise'. But what the document tells us is how much is held right now and whether the holder aims to influence management. So a 5% filing alone is hard to read as a signal that a stock will rise.
When you see news of a big investor buying, look at the stated purpose and the later change reports together. A filing that says the holder has demands for the company, such as taking part in management or general investment, can be read as a sign that further action may follow, while passive investment stays a record that 'we hold it now'. 'Why do they hold it, and do they still hold it afterward?' says more than 'a foreign investor bought 5%'.
