American depositary shares financial
"Each American depositary share represents 18 ordinary shares of Jinxin Technology Holding Company."
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
open-market sale financial
"transaction_action": "open-market sale""
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
indirect ownership financial
"ownership_type": "indirect""
wholly-owned financial
"Light Stream Holdings Ltd. is a British Virgin Islands company wholly-owned by Jun Jiang."
A wholly-owned business is one that is 100% owned by another company, meaning the parent holds all shares and controls decisions. For investors, this matters because the parent company must include the wholly-owned business’s results and liabilities in its own financial picture, so any profits, losses or risks from that unit directly affect the parent’s value—like owning an entire rental property rather than sharing it with partners.
