1. Guarantees: Be suspect of anyone who guarantees that an investment will perform a certain way. All investments carry some degree of risk.
  2. Unregistered products: Many investment scams involve unlicensed individuals selling unregistered securities, ranging from stocks, bonds, notes, hedge funds, oil or gas deals, or fictitious instruments, such as prime bank investments.
  3. Overly consistent returns: Any investment that consistently goes up month after month, or that provides remarkably steady returns regardless of market conditions, should raise suspicions, especially during turbulent times. Even the most stable investments can experience hiccups once in a while.
  4. Complex strategies: Avoid anyone who credits a highly complex investing technique for unusual success. Legitimate professionals should be able to explain clearly what they are doing. It is critical that you fully understand any investment that you are considering, including what it is, what the risks are and how the investment makes money.
  5. Missing documentation: If someone tries to sell you a security with no documentation, such as a no prospectus in the case of a stock or mutual fund, and no offering circular in the case of a bond, he/she may be selling unregistered securities. The same is true of stocks without stock symbols.
  6. Account discrepancies: Unauthorized trades, missing funds or other problems with your account statements could be the result of a genuine error or they could indicate churning or fraud. Keep an eye on account statements to ensure that activity is consistent with your instructions, and know who holds your assets. For instance, is the investment adviser also the custodian? Or is there an independent third-party custodian? It can be easier for fraud to occur if an adviser is also the custodian of the assets and keeper of the accounts.
