What is a share?
An investor who buys shares in a company is a shareholder, and hence a partial owner of that company. A shareholder is willing to take risks. He shares the profit of the company when things go well, but possibly also the losses when the company is not doing well. In the worst case, the shares may lose their value completely, for example in the event of bankruptcy. More information can be found in the information sheet 'What is a share?'.
