You are very deluded.
Your link literally says the disclosure is only correct until March 31st 2025 (went to the link on Square's site to verify this for myself because it's even on your own screenshot!).
6-7 months of stock movement can easily change the entire map.
These disclosures tend to only be required every couple of quarters.
You must be seriously retarded or have some reading comprehension issues.
I posted the oficial data that the Square Enix website as of two days ago, which is updated until the start of the current fiscal year. Back then these folks had nothing at Nintendo, and I wrongly asssumed that there weren't big changes since then because normally there aren't bing changes. Then the other user pointed that these people bought their stocks more recently, after that March 31 point, showing receipts from April or June. I accepted them and rectified. That's all.
Also why on earth would an activist investor outfit publish a report before getting their share holdings together? That's activist investing 101!
People is free to say whatever they want.
In this case, being one of the top shareholders of a company it's normal that they may share their opinion (having a lot of money doesn't mean they are right, there's people saying crazy shit everywhere) and particularly to do it publicly if what they are looking for is to influence the market and particularly the stock value of that company, or the votes of the other main shareholders.
Particularly if there's a shareholder meeting soon, to let the others know their point of view and to put some context on something they may say or ask for there later.
But separate from this specific case, in many companies there's from time to time some 'crazy folk' who has just a few stocks and makes some dumb claims, or are hitmen hired by bigger dogs (often big hedge funds, and these activist happen to be former employees of such company) who try to make some noise to try to negatively affect the company stock value to bring it down letting the big dogs buy cheaper (in gaming see Ubisoft as example, happened a couple times). Normally that dumb folk claim's have no effect, but when it's a hitmen stunt these claims are shared by the hitmen media owned by these big dogs (see Bloomberg as example).
Their idea is to manipulate the stock value of a company to negatively affect their stock price with headlines of "shareholders of X company are very angry and made X claim!" to later buy stocks of that company cheaper.
You often can double check it by looking where the CEO did work previously, to see if there's a hedge fund or big bank there. And if such hedge fund or back bought shares of that company shortly after the company stocks went down shortly after these claims.
