The raising of boards is a measure by stock exchanges across countries to avoid large capital acquisitions that cause stock volatility and cause shareholders to suffer: generally, when a company holds more than 5% of the stock, the buyer has to announce his shareholding ratio to all shareholders, thereby warning and informing shareholders of the risk.
On the 16th of September, Jiadian Group had collectively raised their boards for 23 of Samsung's subsidiaries all over London, Korea, China, Mexico, and other countries!
This also meant that at the same time, Jiadian Group held 5% of the shares of 23 subsidiaries under Samsung.
At that moment, the whole world was shocked.
