Institutional Brokers' Estimate System
Encyclopedia
The Institutional Brokers' Estimate System (I/B/E/S) is a service founded by the New York brokerage firm Lynch, Jones & Ryan and Technimetrics, Inc. I/B/E/S began collecting earnings estimates for U.S. companies around 1976 and used the raw data to calculate statistical time series for each company. The data subsequently was used as the basis for articles in academic finance journals attempting to demonstrate that changes in consensus earnings estimates could identify opportunities to capture excess returns in subsequent periods. After starting with annual earnings estimates and estimates of "Long Term Growth, the database later was expanded to include quarterly earnings estimates. This allowed for the analysis of "Quarterly Earnings Surprises." Other innovations made possible by the I/B/E/S data included estimates for various equity indexes on a "top down" basis (made by strategists and economists) and estimates made on a "bottoms up" basis (by individual analysts) for those same indexes. In the mid-1980s I/B/E/S began to expand its dataset to include companies trading in international markets. Lynch, Jones was sold to Citigroup
in 1986. Barra bought I/B/E/S in 1993, selling it to Primark two years later. Thomson Financial
purchased Primark in 2000; the database is currently owned by Thomson Reuters
.
The I/B/E/S database currently covers over 40,000 companies in 70 markets. It provides to a discriminating client base of 50,000 institutional money managers. More than 900 firms contribute data to I/B/E/S, from the largest global houses to regional and local brokers, with US data back to 1976 and international data back to 1987. http://www.thomson.com/content/financial/brand_overviews/IBES_First_Call
It is unclear why slashes are used in the acronym, vs. periods or nothing at all, but this is its common usage. Users of the data have hypothesized it to be to "demonstrate their uniqueness as a database", a la Using "@" instead of "at".
There are two versions of the I/B/E/S earnings estimate history, Summary and Detail:
Both data sets are available for US and International stocks. The databases cover 56 countries and 70 markets.
