Video Tutorials

Introduction to the Most Commonly Used Databases

Take a guided tour through our datasets using video learning. This first sample video introduces the basics of CRSP, the most comprehensive collection of security price, return, and volume data for the NYSE, AMEX and NASDAQ stock markets. Each video has an accompanying slide deck.

The Additional Video Tutorials link above takes you to the larger repository housing all WRDS video tutorials and slide decks — including — but not limited, to videos on:

Videos on Advanced Research Topics

In addition to the introductory videos, our video library houses tutorials on more advanced research topics. For example, this video demonstrates how to use WRDS Event Study in order to measure the impact on the value of a firm resulting from an event. As with the introductory videos, this video also has a link to a supplemental slide deck.

Research Applications

Citing real-life case studies, our WRDS experts share their proven best practices, based on 25+ years of experience. These Research Applications provide you with sample code that replicates published papers in various topics, such as:

  • Portfolio Construction and Market Anomalies
  • Risk Factors and Industry Benchmarks
  • Risk and Valuation Measures
  • Institutional Ownership
  • Linking Databases

Each application reviews the major findings of the original paper, and presents the sample code (SAS and Python) that replicates the major findings of the paper. Summary table and plots are also included.

WRDS Analytics are powerful tools designed to support you in your research. These include commonly used metrics derived from the raw data. Many analytics tools are computationally expensive due to programming complexity or sheer data size. Here, they are easily available through your browser.

Click the link below for a directory of all the analytics tools, or just click the Analytics tab at the top of the main menu.

Programming with WRDS Data

Your research goals may include accessing and manipulating WRDS data using programming languages, such as SAS, Python, R, MATLAB, and Stata. We have created a series of step-by-step guides for the more popular languages, explaining how to access the data using:

  • Personal computers
  • The Web
  • The WRDS Cloud

Recently, we have added instructions for JupyterHub and RStudio Server. This link takes you to a directory of all our programming documentation, including how WRDS data is structured in PostgreSQL.
