Computer glitches on the Nasdaq stock exchange brought a halt to trading of thousands stocks and options Thursday in what some are calling "the flash freeze."
It's just the latest software malfunction to disrupt the markets, and it's not even the first one this week. Goldman Sachs lost as much as $100 million Tuesday after erroneous algorithmic trades.
This week on Money Talking, guest host Heidi Moore of the Guardian speaks with Joe Nocera of the New York Times and Rana Foroohar of Time magazine about why there are so many software-related problems on stock exchanges these days and whether regulators can do anything about it.
Looking ahead, Foroohar talks about when the Federal Reserve Bank might start tapering off its asset-buying programs.
Nocera talks about e-cigarettes, which are currently not regulated.
