Database Description
Bank Regulatory Database contains five databases for regulated depository financial institutions. These databases provide:
  • accounting data for bank holding companies
  • commercial banks
  • savings banks
  • savings and loans institutions
The source of the data comes from the required regulatory forms filed for supervising purposes.
Beta Suite by WRDS This is a powerful web based tool allowing researchers to calculate stocks’ loading on various risk factors in a timely way. The tool is designed with flexibly in mind, capable of handling monthly, weekly and daily rolling regression on common set of market risk factors.
Blockholders This dataset contains standardized data for blockholders of 1,913 companies. The data was cleaned from biases and mistakes usually observed in the standard source for this particular type of data. Blockholders' data is reported by firm for the period 1996-2001. The data cleaning procedure is explained in detail by Jennifer Dlugosz, Rudiger Fahlenbrach, Paul A. Gompers, and Andrew Metrick in their study "Large Blocks of Stocks: Prevalance, Size, and Measurement".
BoardEx Access extensive data on the boards of publicly listed and notable private companies of North America.
Bureau van Dijk It is widely recognized as a specialist provider of both public and hard to reach private company information within the academic community. The only data product from Bureau van Dijk that we are subscribed to through WRDS is Orbis, which has financials and interim-financials information for industrial companies, banks and insurance companies in Europe. Orbis also has first level information for all subsidiaries and current shareholders.
CBOE Indexes Volatility Index® (VIX®) is a key measure of market expectations of near-term volatility conveyed by S&P 500 stock index option prices. The Vix Index was introduced in 1993 by Professor Robert E. Whaley of Duke University in his paper "Derivatives on Market Volatility: Hedging Tools Long Overdue," Journal of Derivatives 1 (Fall 1993), pp. 71-84. Since then, VIX has been considered by many to be the world's premier barometer of investor sentiment and market volatility.
The New VIX still measures the market's expectation of 30-day volatility, but in a way that conforms to the latest thinking and research among industry practitioners. The New VIX is based on S&P 500 index option prices and incorporates information from the volatility "skew" by using a wider range of strike prices rather than just at-the-money series.
Compustat It is a database of financial, statistical and market information on active and inactive global companies throughout the world. The annual company data history available back to 1950 and quarterly data available back to 1962.

Efficient Frontier by WRDS This is an interactive tool to learn how risk and return characteristics change as stocks are added and removed from a hypothetical portfolio. The application is designed to help you visualize key concepts in diversification and portfolio optimization as you manipulate portfolio parameters and observe the results.
Event Study by WRDS The event studies are widely used by empirical researchers in finance, economics, accounting, law, and other business disciplines to analyze the market reaction to firm specific and market-wide events using either returns or volume around the time when event occurred.
Some examples include: earnings announcements, M&As, new capital issues, and announcements of macroeconomic variables (unemployment or trade deficit), measure impact on the value of a firm resulting from a change in the regulatory environment, or to assess the damages.
Fama French & Liquidity Factors The Fama-French Portfolios are constructed from the intersections of two portfolios formed on size, as measured by market equity (ME), and three portfolios using the ratio of book equity to market equity (BE/ME) as a proxy for value. Returns from these portfolios are used to construct the Fama-French Factors. Eugene Fama and Kenneth French showed that their factors capture a statistically significant fraction of the variation in stock returns (see "Common Risk Factors in the Returns on Stocks and Bonds", Journal of Financial Economics 33, 1993). The Fama-French data source is Kenneth French’s website at Dartmouth.
The Pastor-Stambaugh Liquidity series are described by L. Pastor and R. F. Stambaugh in "Liquidity risk and expected stock returns" (2003, Journal of Political Economy 111, 642-685). This set includes ‘non-traded’ and ‘traded’ liquidity factors, with the latter series derived from dividing common stocks (in the CRSP monthly stocks file data) into 10 groups based on each stock’s sensitivity to the ‘non-traded’ liquidity innovation factor (as described in the paper).
The Sadka Liquidity measures are described in R. Sadka in "Momentum and Post-Earnings-Announcement Drift Anomailes: The Role of Liquidity Risk" (2006, Journal of Financial Economics 80, 309-349). The measures are non-traded, market-wide, undiversifiable risk factors. Price impact is separated into permanent (variable) and transitory (fixed) price effects.
