Buying shares has always been regarded as a relatively successful form of investment. Profits are gained through the receipt of dividends and from the increased value of the shares when they are sold. Historically, share prices rise and so profits in trading shares rise. Although for many years this has been a good form of investment, it has its risks. Share prices can go down as well as up. As a short term investment, the potential gains and potential losses are likely to be greater. It’s best to see buying and selling shares as a steady long term investment.

When buying shares its usually best not to keep all your eggs in one basket, but to spread the risk by holding a diverse portfolio of shares. If you have all your shares in the oil sector and the sector rockets, all well and good. However if there is a slump, in that sector you could be in real trouble.
