Nervous investors, troubled popular stocks, lessons from Morningstar and more

Greg McBride, chief analyst for BankRate.com, says that while the site's latest survey shows that few Americans are boosting their stock holdings right now, a majority is still as committed to buying stocks as they were a year ago, with more than half of U.S. investors saying they purposely had made no moves in response to current market volatility. In The Big Interview, Ken McAtamney, who runs the William Blair Global Leaders fund, discusses where there are leading companies -- now often trading at discounts -- amid the current market confusion, David Trainer of New Constructs puts Spotify and Pinterest back into "The Danger Zone" because they still have lots of room to fall despite recent setbacks, and Chuck talks about the four lessons he took away from last week's Morningstar Investment Conference in Chicago.
