American depositary share financial

"Each American depositary share represents one ordinary share, par value US$0.0001 per share"

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

Rule 10b5-1 trading plan regulatory

"The sales reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average price financial

"Represents the weighted average price of shares sold at prices that ranged from"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

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.
