The share is an equity representing the right of ownership in a specific joint stock company. Among the rights attaching to the shares, we distinguish between ordinary and preference shares. Ordinary shares give the holder the right to vote in the general assembly of the company, the right to pay part of the company's profits and the right to pay part of the rest of the company's liquidation or insolvency estate, while the preference shares give some preferential rights. Investment in shares is considered a profitable method of capital use. However, it is necessary to know the subtlety of the stock exchange and to have basic knowledge in the financial sector.
