American depositary shares financial
"reported small open-market sales of American depositary shares (ADS) of NAMI"
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
"Light Stream sold 10,000 ADS at $0.345 and a further 100 ADS in an 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.

"Following these transactions, Light Stream’s indirect holding is reported at about 2,998,330 ADS"
Form 4 regulatory
"The Form 4 reports an indirect post-transaction holding of about 2,998,330 ADS"
Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
