"Watch Out For These Warning Signs of Fraud
Get-rich-quick schemes that sound too good to be true. There’s never a free lunch. Be very careful if you recently retired or came into money and you’re looking for a safe investment. You could be a very attractive target for a crook. Once your money is gone, it can be impossible to get it back.
Predictions or guarantees of large profits. Always get as much information as you can about a firm or individual’s track record and verify that information—even if you know the people involved or they are recommended by friends or relatives. If you can’t get solid information about your investment and the company, don’t invest. Before you invest, always check it out with someone whose financial advice you can trust.
Promises of little or no financial risk. Be suspicious if the firm or individual says there is little risk. Be suspicious if someone tells you that a written risk disclosure statement is only a routine formality. Written risk disclosure statements are important to read thoroughly and understand.
Claims of trading in the “Interbank Market.” If a firm claims that they will trade foreign currency for you in the interbank market, or that you should trade in the interbank market, be cautious. The term “interbank market” refers to a loose network of currency transactions negotiated between financial institutions, usually banks and investment banks, and other large companies.
Unsolicited telephone calls about investing. Be skeptical if someone you don’t know calls you about investment opportunities.
Someone asking you to send cash immediately. Be very cautious if someone tries to convince you to send cash or transfer money to them immediately by overnight express, the Internet, mail, or any other method."
