Once a quarter, the top management of nearly every publicly traded company in the U.S. gathers around a speakerphone or webcam in a conference room and talks to brokerage firm analysts about earnings. The calls begin with prepared remarks that provide an overview of last quarter\u2019s performance, followed by a question-and-answer session.<\/p>\n

The ritual started in the latter part of the last century and has become a leading way for firms to communicate to investors. Although the companies\u2019 prepared remarks summarize the high points, what else is revealed in those earnings calls?<\/p>\n

Three Owen professors are on a quest to find out.<\/p>\n

Catherine Lee, Michael Stuart and Richard Willis are working with the Vanderbilt Libraries on a cutting-edge trans-institutional research project that makes the content of more than 15 years of earnings\u2019 conference calls accessible and available for analysis.<\/p>\n

Their intent is to examine whether the sentiment (positive, negative, neutral) of management responses to analysts\u2019 questions are associated with the magnitude of the analysts\u2019 forecast revisions. \u201cWe also want to see whether individual analysts on the same call revise their forecasts differently based on the sentiment of the response they receive to their specific questions,\u201d says Stuart, assistant professor of management.<\/p>\n

For their research, the team needed access to a large number of earnings\u2019 conference call transcripts and the ability to read and analyze the reports efficiently and consistently. They turned to Hilary Craiglow, director of the Walker Management Library, who provided guidance and helped Vanderbilt negotiate a deal with top electronic information company LexisNexis to provide greater access to its academic databases. Clifford Anderson, director of scholarly communications for the university library system, helped the researchers think through tools they could use to read these documents.<\/p>\n

As a result, the business professors are using advanced technological tools to extract and analyze huge amounts of text. Lee, Stuart and Willis access the library\u2019s LexisNexis Academic database via a new application program interface. The API removes the built-in interface on the LexisNexis database and allows the researchers to set up their own methods for querying and collecting information. Anderson is assisting with data extraction and modeling for the project.<\/p>\n

\u201cEarnings conference calls of publicly traded firms contain a wealth of information that is just beginning to be explored,\u201d Stuart says. \u201cThese tools have put us on the cutting edge of accounting research.\u201d<\/p>\n

Lee, assistant professor of management, says that the project will increase knowledge about the role of communication between analysts and managers in providing information to current or potential firm stakeholders. \u201cOur research will be the first study to investigate the direct interchanges between analysts and managers on earnings conference calls,\u201d she says.<\/p>\n

The earnings project utilizes only a small portion of the LexisNexis database. \u201cWe can think of the LexisNexis API as a back-door portal to large amounts of information available in a semi-structured format,\u201d Craiglow says. \u201cOur researchers are capturing massive amounts of text in a machine-readable format for analysis and detection of patterns.\u201d<\/p>\n

LexisNexis Academic content includes text of thousands of newspapers, journals, transcripts and wire services covering a wide breadth of disciplines, including business, law, education, political science and others.<\/p>\n

The project has spawned solutions for research by other Vanderbilt faculty. Jonathan Gilligan, associate professor of Earth and environmental sciences in the College of Arts and Science, wanted to analyze text in published news stories regarding water conservation in U.S. cities. The libraries\u2019 Anderson put him in touch with Craiglow.<\/p>\n

As a result, Gilligan and his team are using the LexisNexis API for a comprehensive study of newspaper coverage of water issues.<\/p>\n

John Sloop, associate provost for digital learning, says he\u2019s interested in using the technology for his own research in communications studies but that he\u2019s more impressed by the trans-institutional orientation of the project. \u201cHere we have a project initiated by Owen researchers that led to a solution negotiated by the management library, which came to the attention of a team of researchers in Earth and environmental science\u2014and they shared it with other faculty,\u201d he says. \u201cOur trans-institutional orientation and emphasis on digital technologies can make for fruitful\u2014and often unexpected\u2014outcomes.\u201d<\/p>\n

Integral to the Owen research project and others is the libraries\u2019 growing digital expertise. \u201cWe are pleased to be able to license huge amounts of text for many different disciplines,\u201d Craiglow says. \u201cThese tools have tremendous potential for cross-disciplinary research.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
