Buying shares in Facebook is likely to offer you a good return on your investment in dividends. There is little doubt that Facebook Shares will continue to grow over the next few years. Buying a small number of shares in Facebook is therefore probably a good move if you have spare cash to invest. But it is almost certainly unwise, however, to invest a large amount in Facebook. The simple reason for this is that investing in Facebook is not really an investment. Investing is about examining the values and potential of a company in detail and weighing up the risks versus the potential for profit that is offered by the investment.
Remember that private investors have already had the best pickings of the company before this public offering and consider if there is a less flashy but more profitable option available to you before investing in Facebook.
