Moreover, he explains why most people are mistaken in their understanding of how diversified – or not – the index actually is. Listen for tips on how to make sure your portfolio is well-diversified. Sometimes the best way to diversify is getting outside help. Watch here to see what type of money managers can help diversify your portfolio.

Does today's market contain new patterns or does it reflect historical trends?

Jill Schlesinger, CFP® and business analyst at CBS news, joins Doug to explore whether today's economic landscape is significantly different than it was in the past. If so, should retirement planning and investment plans reflect the new outlook? Jill believes that the global recession taught investors how to look at the future, and we shouldn't look for a "best-case" scenario, but for the most reasonable scenario. She asserts that the best protection for all investors (including Americans living abroad) is a broadly diversified portfolio. Jill gives advice on what you should do if you think the market is particularly volatile. If you anticipate a big market crash, what move should you make? Listen to Jill and Doug's discussion to find out when a healthy dose of cynicism pay off, and how to prevent self-inflicted market wounds.
