Wharton Research Data Services Gives Best Paper Award for Research Measuring Volatility of Risk Indices

Philadelphia, PA (BusinessWire) — Wharton Research Data Services (WRDS), the leading data research platform and business intelligence tool for corporate, academic and government institutions worldwide, is pleased to announce Ian Martin, Professor of Finance at the London School of Economics and Christian Wagner, Professor of Finance at the Copenhagen Business School as the winners of the WRDS Best Paper Award at the Western Finance Association. Their paper, “What is the Expected Return on a Stock?,” introduces a new approach to one of the classic questions in financial economics, which is of interest both to academics and to practitioners. The authors exploit derivative price data to understand equity market behavior and associated risks. A part of the Wharton School of the University of Pennsylvania, WRDS provides global corporations, universities and regulatory agencies the thought leadership, data access and insights needed to enable impactful research.

Martin and Wagner show how to extract information about future stock returns from derivative prices by defining volatility indices based on index and stock options.

These volatility indices are easily constructed, and they can be used to forecast individual stock returns in real time. This research has broad practical and academic applications.

Key points:

  • Provides new model of measurement for expected returns based on index and stock options pricing.
  • Research was conducted via WRDS using CRSP, Compustat, and OptionMetrics.

“WRDS is pleased to present the WRDS Best Paper Award to Professors Martin and Wagner for their efforts to uncover new models of assessing expected returns,” said Robert Zarazowski, Managing Director of WRDS. “On behalf of WRDS, I am delighted to congratulate Martin and Wagner on their outstanding work.”

“Christian and I are extremely grateful to WRDS for this Best Paper Award,” said Ian Martin. “It is a true honor to have our work recognized in this way, and to be able to share our findings with the research community.”
