The effects of trading halts on price discovery for NYSE stocks

Taylor &​ Francis Ltd.


This article uses intraday data for the year 1992 to investigate the effect of trading halts on price discovery for stocks traded on the New York Stock Exchange. The results show that the degree of benefits from trading halts depends on the types of halts and significance of the news items. It is found that trading halts reduce price dispersion when trading is halted due to imbalance in order flows. Such a positive effect is robust to the significance of news items. Trading halts can help price discovery when trading is halted due to the fact that some significant news items already hit the market and investors need more time to digest the impacts on price. In contrast, when officials call for the halt due to the pending news release with little significance, trading halts actually inject more noise into the prices and undermine the price discovery process. Overall, the results are consistent with the argument by exchanges that trading halts help dissipate information and facilitate the price discovery process.

The Market for Equity Options in the 1870s

American Finance Association


The introduction of exchange-traded options in 1973 led to explosive growth in the stock options market, but put and call options on equity securities have existed for more than a century. Prior to the listing of option contracts, trading was conducted in an order-driven over-the-counter market. From 1873 to 1875, quotes for options contracts were published weekly in The Commercial and Financial Chronicle during a period that saw extensive marketing efforts by a number of brokerage firms. In this article we examine these quotes to determine why this seemingly sophisticated market existed for only a brief period in financial history.

Banking's Uber moment: The future of investment banks

Forbes India  online


Investment banking has always been a highly cyclical business, growing when the markets grow, shrinking when they shrink. But a combination of regulation, technology and investment suggests that, as stockbrokers have traditionally whispered in boom times, this time it’s different. The go-go era of investment banking that began in the mid-1980s and thrived up to the financial crisis appears to be on its way out, as the biggest banks shrink in response to regulation and smaller, more focused firms, funds, and start-ups take a larger share of the market. “It’s becoming a mature industry,” says George Kuznetsov, a London-based member of the executive board at Coalition, a banking data firm. Over the past few years, the number of banks with aspirations to become one of the world’s top three investment banks has shrunk from 10-15 to three, says Kuznetsov. Six years ago, in 2009-2010, all those large banks aspired to be one of the top three of almost everything. No longer. “At this point in time, that mentality doesn’t exist,” he says.
