Many companies raise capital by making a fixed number of shares in the company available for sale on the stock market and issue share certificates in return for their purchase.

Each share offered will be of equal value and attract certain privileges, including voting rights and a share of the company's net profit (often paid in twice yearly dividend instalments, the proportion of which will be relative to the amount of shares you hold in the company).

However, the actual monetary value of a share at a given point in time depends on the demand for the company's product or services and it is this variable which makes share dealing shares a unpredictable investment.

Investors buy shares because they can earn you an income in one of two ways:

  • Dividends - a dividend is a reward paid out to investors, often twice a year and tied to the companies overall performance. The amount you'll receive is proportional to how many shares you hold

  • Growth - if the amount your shares are worth goes up, you can sell them at a profit. But don't forget: what can go up can also come down

You can buy shares in any PLC listed on the stock market, all you need is a share dealing account. This means investing can be a good alternative to traditional interest-paying savings.

In general, investing in share is, over time, likely to produce higher returns than simply leaving funds in a savings account where they are unlikely to grow above inflation.

However you must remember that with the potential for increased profits from share dealing there is also the risk of loss. Consequently, you should view share dealing services as a medium to long term investment in order to counteract the inevitable fluctuations of the stock market.

Also be sure to remember that the money you invest is at risk when you purchase shares, so be sure to only invest money that you could afford to lost and ensure that you have other financial arrangements in place in case you don't profit from the investment.
