Any investment carries a certain level of risk, and may not be suitable for all investors. The degree of leverage can work against you as well as for you. Before deciding to trade/invest in the stock market, you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. (DO NOT INVEST YOUR EMERGENCY FUND IN THE STOCK MARKET.)
