Course
Big Data Asset Pricing

Faculty
Lasse Heje Pedersen (LHP) and Theis Ingerslev Jensen (TIJ)

Course coordinator
Lasse Heje Pedersen

Prerequisites
The course is designed as a first-year Ph.D. course. The prerequisites are knowledge of asset pricing theory and econometrics at a M.Sc. level and an ability to work independently with data using a programmatic computer language such as Matlab, R, or Python. Students must participate in the whole course and do all problem sets.

Aim
The aim of the class is to introduce Ph.D. students in finance and related fields to empirical asset pricing research methods using big data.

Course content
The course provides students with empirical asset pricing tools to use big data to analyze modern topics in financial economics. The course starts with a quick overview of asset pricing, empirical asset pricing, and how to work with big financial data. The course then covers the factor zoo, multiple testing adjustments, replication, machine learning in asset pricing, and asset pricing with frictions. In addition to the theoretical discussion, the students will gain access to a large data set of global equity returns and use this data to solve several mandatory exercises, which constitute an essential part of the course. Each student must make their own solution to each exercise and be able to explain this solution and present it.  Students are allowed to discuss the exercises and solution methods, but students are not allowed to copy each other. Students must disclose in their solutions if code has been copied from public sources (using public code is perfectly fine, but should be disclosed), and should disclose any other material used.

Learning objectives
The course objectives are to:
• Work with big financial data, including making factors
• Apply factor models to estimate risk and expected return
• Estimate stock return predictability via regressions and portfolio sorts 
• Evaluate potential replication crisis and the factor zoo
• Implement multiple testing adjustments using frequentist and Bayesian methods
• Apply machine learning to asset pricing data
• Analyze financial market frictions

Exam
There is no final exam, but students must satisfactory complete of all the mandatory exercises. The class is graded as pass/fail.

Other
The course is offered through The Nordic Finance Network, and the Department of Finance at CBS will cover the course fee for PhD students from other NFN associated universities.
