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.

CBOE Indexes

The CBOE (Chicago Board Options Exchange) 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.


S&P Capital IQ's Compustat North America is a database of U.S. and Canadian fundamental and market information on active and inactive publicly held companies. It provides more than 300 annual and 100 quarterly Income Statement, Balance Sheet, Statement of Cash Flows, and supplemental data items.

S&P Capital IQ's Compustat Global
S&P Capital IQ's Compustat Global is a database of non-U.S. and non-Canadian fundamental and market information on more than 33,900 active and inactive publicly held companies with annual data history from 1987.  S&P Capital IQ's Compustat Global is a database of non-U.S.data is unique in that it is normalized to provide comparability across a wide variety of global accounting standards and practices. Accounting standards vary considerably among countries, making accurate comparisons of as-reported data somewhat difficult. Rather than adopt one country’s set of accounting principles as the standard for collecting data from all countries, we have created consistent sets of financial data items for the Global database by examining financial statements from a variety of countries and identifying items that are widely reported by companies, regardless of their geographic location, business activity or accounting practices. Within these uniform data sets, we normalize the data to local accounting principles, disclosure methods and data item definitions. As a result, you can make more meaningful comparisons among industries and countries.

Also Includes:

  • Bank
  • Historical Segments
  • Customer Segments
  • Compustat Quarterly Updates
  • Execucomp
  • Marginal Tax Rates

Fama-French Portfolios and 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 web site at Dartmouth.
