The price of a Carrefour share fluctuates according to stock market conditions and economic or financial events affecting the company. There is therefore no fixed price to buy a Carrefour share, but rather a real-time price determined by supply and demand on the stock market. Over the last few years, the Carrefour share price has fluctuated in a range between 11 and 30 euros. To find out the current price of a Carrefour share, it is advisable to refer to a trading platform or a real-time financial information website, which provide updated stock market prices in real time. However, it is important to bear in mind that buying individual shares can involve risks and that the decision to invest in a company should be made on the basis of a thorough analysis of the company and its future prospects.
