INVESTMENT RISKS

There are risks associated with investing in securities. Investing in stocks, bonds, exchange traded funds, mutual funds, and money market funds involve risk of loss. Loss of principal is possible. Some high risk investments may use leverage, which will accentuate gains & losses. Foreign investing involves special risks, including a greater volatility and political, economic and currency risks and differences in accounting methods. A security's or a firm's past investment performance is not a guarantee or predictor of future investment performance.
