M0nica The price of a share reflects the value of the business that it is invested in. A successful business with a good return on capital and secure and growing markets will have a higher share value than a similar sized company with a poor return on capital and in a market that is declining, making diesel cars, for example.
People and organisations invest in companies not just for capital growth but also for dividends. My, and most people's occupational pensions are paid from dividends received and income on bonds.
It is no difference from buying a house from a builder and then selling it on. Someone buys shares in a new business and some years later wants to sell them on. If the company they bought shares in is now a big thriving company then their shares are worth more as a proportion of the company's value.
Spot on.
Risk-reward, choose wisely and hopefully be well rewarded.
