持股 (chí gǔ) literally means 'to hold shares' — 持 (chí) means 'to hold, to possess', and 股 (gǔ) refers to 'a share of stock' or 'equity'. Together, they form a verb meaning to own or hold equity in a company, whether as an individual investor or institutional stakeholder. It emphasizes ownership status rather than the act of buying; it describes the state of possessing shares.

This term is common in financial news, corporate reports, and investment discussions. It often appears with quantifiers (e.g., 持股比例 'shareholding percentage') or in passive constructions (e.g., 被持股 'is held by'). While technically neutral in register, it’s formal and rarely used in casual speech — you wouldn’t say 持股 when telling a friend you bought some stock; instead, you’d use 买了股票 or 投资了股票.
