The market is crashing. What will you do with your investments? Your risk tolerance, defined by Investopedia as "the degree of uncertainty that an investor can handle in regard to a negative change in the value of his or her portfolio," largely determines your reaction. Equally important, risk tolerance, in addition to your investment objectives and experience, time horizon, and financial situation, should play a critical role in how you allocate your investment assets. The newly created Moneysmartz Risk Tolerance category includes links to online tests to help you determine your risk tolerance and articles to help you understand how risk tolerance relates to asset allocation. Be sure to visit the Wikipedia Stock Market Crash listing to learn about situations that are sure to test even the most risk tolerant.
