What is the main topic discussed in this episode?
With your money briefing, I'm J.R. Whelan at The Wall Street Journal in New York.
What surprising finding kicked off the investigation into stock-market gaps?
Something peculiar turned up when a study was conducted to figure out how stock markets might respond to a cyber attack. And it has some stock market traders steaming mad. We'll explain in a moment. First, these money and market stories you should know. Economists were taken by surprise when December retail sales figures came out and showed a 1.2% drop from a month earlier. That's the largest drop since 2009.
How did December retail sales and broader economic news set the scene for this story?
The Commerce Department report showed every major retail category, aside from motor vehicles and building materials, posted sales declines in December. The final month of the holiday season is key for the sector, especially for department stores, clothing outlets and online sellers. The Journal's Heard on the Street team says that initial credit card data indicates that sales may wind up having dipped again in January. But Heard on the Street says the government shutdown was in effect throughout much of January, while the Arctic air mass that sent temperatures plunging late in the month kept people indoors. And the Education Department's inspector general says the government has failed to properly oversee companies
that collect Americans' federal student loan payments, and that it is possibly contributing to a rise in defaults and driving up taxpayer costs. The journal's Josh Mitchell reports in recent years advocates of borrowers have criticized the companies for not doing more to help borrowers in financial distress to reduce their monthly payments through options such as programs that set their monthly payments as a share of their incomes. That's also known as income-driven repayment. Congress has gotten involved trying to find a solution because millions of borrowers have defaulted on their loans in recent years. Also, the U.S.
What prompted the government-funded study about markets and cyberattacks?
government is a major player in college loans. It's the country's biggest student loan provider, with roughly 43 million Americans owing a combined $1.44 trillion in federal student debt.
A study funded by the U.S. government to better understand how U.S. markets might respond to a cyber attack turned up scenarios where trades on equity markets might not be executed at the best price available due to pricing discrepancies.
How do fragmented exchanges and different data feeds create price discrepancies?
Wall Street Journal investigative reporter Cesare Podcol is here to explain the significance of this. So, Cesare, the study revealed about a quarter of all trades in 2016 were executed at prices that weren't the best available in the market. And this is because of different prices of a stock across different exchanges?
Yeah, so the U.S. stock market is very fragmented. There are now 13 stock exchanges and dozens of off-exchange venues known as dark pools where orders may be executed. So most of the time the market follows the law of one price in that there's just one best bid and one best offer for stocks sold across these markets. And that's called the National Best Bidder Offer, which gets reported on a regulatory data feed called the Securities Information Processor. And that's the price at which your broker must seek to execute your trades to ensure you get the best price. But there are times when this national price can diverge from prices disclosed in proprietary data feeds that are sold by exchanges. And that was the focus of the study.
The researchers found that about three-fourths of the trades they analyzed were executed during times when the best price is published on this market. regulatory data feed were in sync with the best prices available in exchanges. But about a quarter of them happened during a time when the exchange's data feeds showed a different, often a better price.
How did the Apple example illustrate the real cost of price gaps to investors?
And that was what they drilled into, and they looked at, okay, what happened during that time, and did investors get the best price available at the time?
What exactly did they determine is the cause of these discrepancies across the exchanges?
So it's because you've got these two sources of information, the data feeds sold by exchanges and this regulatory data feed where the best prices are reported, and they may not always be in sync.
