# Asset pricing data at OSE

This page contain some calculated data useful for academic asset pricing
investigations at the Oslo Stock Exchange.
## Source of data

The source of the raw data is daily observations of stock market data from the
Oslo Stock Exchange Data Service. From this data I calculate a number of
different derived time series:
- Asset pricing factors for the Oslo Stock Ecchange similar to those
developed by Eugene Fama and Ken French (See the homepage of Ken
French:
Data Library
- Market portfolio returns

I am grateful to Oslo Stock Exchange for allowing me to publish these data.
## Period

Data is from 1980:1 to 2019:12
Note that the accounting data post-2010 are sourced from Datastream, the OSE data service has
stopped providing accounts. This may lead to some discrepancies when comparing to the previously
calculated SMB and HML series, the current ones are using the B/M ratio for the whole firm when
sorting on B/M, with data from the OSE 1980--2010, and from Datastream from 2010 onwards.

Also note that the Fama French factors for the period 2017-2019 are preliminary, they are likely
to be revised based on new accounting data.
