"株" (kabu) refers to stocks or shares in a company. When individuals buy stocks, they purchase a small ownership stake in that company. This ownership can provide dividends, which are a portion of the company's profits, and the potential for capital gains if the stock's value increases over time. Investing in stocks is a common way for people to grow their wealth. The stock market, where these transactions occur, is influenced by various factors, including economic conditions, company performance, and investor sentiment. Many people use stock trading platforms to buy and sell their shares in companies like Apple or Toyota.
