Research Webinar | I/B/E/S Unpacked

I/B/E/S is one of the most widely used sources for analysts' expectations in empirical finance and accounting research. Yet important questions about data provenance, coverage, historical revisions, identifiers, and consensus construction can have significant implications for research design and reproducibility.

In this webinar, we sit down with two product specialists from LSEG to discuss I/B/E/S and its underlying data methodology. Drawing on this institutional knowledge, they address the questions researchers most need answered before building I/B/E/S into their empirical work: How is coverage determined, and where are the gaps? What does the data collection process actually look like, and how has it evolved over time? How should researchers navigate identifiers when linking I/B/E/S to other datasets? And how, precisely, is analyst consensus established?

Whether you're a seasoned I/B/E/S user or working with the data for the first time, this conversation offers practical, methodology-level insight that can strengthen your research design and support more reproducible results.

Fama-French SMB and HML | SAS Replication

The goal of this application is to reproduce, as closely as possible, the Fama-French SMB and HML factors in order to provide researchers with a set of programs that can be modified to further advance research in this area. This tutorial presents a step-by-step replication of the SMB and HML Fama-French factors using SAS, including:

  • Using Compustat data to calculate book value of equity
  • Using CRSP stock data for portfolio formation
  • Merging of CRSP and Compustat data
  • Portfolio formation
  • Calculating the Fama-French factors
  • Comparison of results with Ken French's data

A series of additional videos describes each of the calculations behind these steps in more detail.
