A stock is a type of security that confirms an investor's ownership of a portion of the capital of the issuing company. Recently, stocks have been the focus of attention in Vietnam when the stock market witnessed a strong increase in VN-Index, but many individual stocks simultaneously dropped deeply in price, leaving investor accounts in the red. This situation reflects the complexity and unpredictable fluctuations of the market, requiring investors to always monitor closely.
