Form 3 regulatory

"INSIDER FILING DATA (Form 3)"

Form 3 is the initial public filing that officers, directors and large shareholders must submit to report their ownership of a company’s securities when they become insiders. It acts like an opening inventory sheet that gives investors a starting point to see who holds significant stakes and to spot later trades or potential conflicts of interest, helping assess insider confidence and transparency.

American depositary shares financial

"security_title": "American depositary shares""

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.

indirect ownership financial

""direct_or_indirect": "I", "ownership_type": "indirect""

ordinary shares financial

"security_title": "Ordinary shares""

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

wholly-owned financial

"Light Stream Holdings Ltd. is a ... 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.
