Economist William Silber says that when investors have downside protection and the potential for limited losses against big possible gains, it is time to be a gambler and to be a little reckless. Silber whose new book out this week is 'The Power of Nothing to Lose: The Hail Mary Effect in Politics, War, and Business,' discusses the times when gambles and risk-taking make sense, though he notes that most of those speculations are more for entertainment than for building wealth. Also on the show, Rita Assaf of Fidelity Investments, discusses the firm's latest survey of parents on students on changing college-savings and planning, Chuck answers a question about the appropriateness of default choices in retirement plans, and Ivana Delevska, founder of SPEAR Invest, talks industrials and industrial-technology stocks in the Market Call.
