A CLI tool using the Quandl API and the Sharadar Fundamentals database.

Project description

quandl_fund_xlsx

https://img.shields.io/pypi/v/quandl_fund_xlsx.svg https://img.shields.io/travis/robren/quandl_fund_xlsx.svg Documentation Status Updates

A unofficial CLI tool which uses the Quandl API and the Sharadar Essential Fundamentals Database to extract financial fundamentals, Sharadar provided ratios as well as calculate additional ratios. Results are written to an Excel Workbook with a separate worksheet per ticker analysed.

Features

For a given ticker, fundamental data is obtained using the Quandl API and the Sharadar Fundamentals database. This data is then used to calculate various useful, financial ratios. The ratios include

  • Profitability indicators
  • Financial leverage indicators
  • Free and Operating Cash flow indicators.

Some REIT specific ratios such as FFO are very roughly approximated. These specific ratios are only roughly approximated since certain data, namely Real estate sales data for the period does not appear to be available via the API (It’s often buried in the footnotes of these companies filings).

The output excel worksheet for each ticker processed is divided into three main areas:

  • Sharadar statement indicators. This is data obtained from the three main financial statements; the Income Statement, the Balance Sheet and the Cash Flow Statement.
  • Sharadar Metrics and Ratio Indicators. These are quandl provided financial ratios.
  • Calculated Metrics and Ratios. These are calculated by the package from the Sharadars data provided and tabulated by the statement indicators and the ‘Metrics and Ratio’ indicators.

The python Quandl API provides the ability to return data within python pandas dataframes. This makes calculating various ratios as simple as dividing two variables by each other.

The calculations support the data offered by the free sample database (formerly referred to by Sharadar as the SF0 database), and the paid for SF1 database. The coverage universe is the same for both the sample data and the paid database. The key difference being, support as well as a much richer set of so-called Dimensions (timeperiods). For example the sample data is taken from the annual filings of companies, whereas the paid data allows for Trailing Twelve Month as well as quarterly data.

Note: For quarterly data, many of the ratios using income and cash flow statement values in the numerator will be inaccurate when using quarterly data e.g EBITDA/Intereset expense or Total Debt/ Cash Flow from Operations.

Installation

pip install quandl_fund_xlsx

Configuration

You will need a Quandl API key. This maybe obtained by signing up, for free at Quandl Signup. The key will then be available under “profile” when logging into Quandl. This key allows for access to sample data for many of the datasets.

If you have have a key for the free sample data set the QUANDL_API_SF0_KEY environment variable to the value of your key.

If you have paid for access to the Sharadar fundamentals data set, then set the QUANDL_API_SF1_KEY in the environment.

export QUANDL_API_SF0_KEY='YourQuandlAPIKey'

or

export QUANDL_API_SF1_KEY='YourQuandlAPIKey'

For windows the setx command is used to set environment variables..

Local Development

This section is only of relevance if you wish to hack on the code yourself, perhaps to add new ratios or display other Sharadar provided data values.

It’s recommended to setup a virtual environment and perform the installation within this. Use pip to install the requirements but not the package.

pip install -r requirements_dev.txt

# Run the CLI by running as a module
python -m quandl_fund_xlsx.cli -t MSFT

# Run the tests
pytest

If you wish to install the package locally within either a virtualenv or globally this can be done once again using pip.

pip install -e .

# Now the CLI is installed within our environment and should be on the
# path
quandl_fund_xlsx -t MSFT

History

0.1.1 (2017-08-31)

  • First release on PyPI.

0.1.2 (2017-08-31)

  • Change logging to INFO from DEBUG

0.1.3 (2017-08-31)

  • Minor tweak to Return the correct version

0.1.4 (2017-11-06)

  • Removed the –dimension CLI keyword. Now uses Most Recent Year (MRY) for SF0 database and Most Recent Trailing 12 Months (MRT) for the SF1 database
  • Fix to avoid the Pandas future warning about decrementing df.rename_axis and using df.rename

0.1.6 (2018-01-26)

Now uses the get_table methods from the quandl_api.

0.1.7 (2018-05-10)

  • Fix bug where the dataframe returned from quandl qas not being sorted
  • Added EPS and EPS diluted.

0.1.8 ( 2018-05-24)

  • Fix bug where the SF0 subscription data was not being returned.
  • With the discontinuation of the Sharadar Time series API at the end of March 2018, the codes for the free fundamental subscription SF0 database changed. Subscribers to the SF0 data now use the SHARADAR/SF1 code in the get_table accesses.

0.1.9 ( 2018-06-11)

  • Added back support for the –dimension CLI option.

0.1.10 (2018-10-29)

  • Added some new Cash Flow related ratios and corrected the LTDEBT ratios
  • Changed the default to be the paid SF1 Database as this is the one I’m using and testing. Requires a separate free SF0 subscription to test SFO. All of the API calls whether the user has an SFI paid membership or SF0 use the SF1 codes.

0.2.0 (2018-11-13)

  • After learning that the sample data API now allows _all_ of the same indicators as those available using the paid SF! aPI key I was able to remove a lot of special case code for the Sample data KEY. The paid KEY allows for many more dimensions to be queried.
  • The CLI now defaults back to using the sample data SF0 API key.
  • Added a number of Cash Flow from Operations based metrics as well as some Free Cash Flow based metrics.
  • Added a development test which uses the API and a sample data or SF0 API key to extract ratios for AAPL.
  • Added Excess Cash Margin ratio.

0.2.1 (2018-11-13)

  • Minor security fix, requests version now >=2.20.0
  • Minor documentation cleanup

0.2.2 (2018-11-13)

  • Add support for the MRQ and ARQ dimensions.
  • Correct error in calculating CAGR when the data was given in quarterly increments.
  • Correctly reference the Excel spreadsheet example figures in the README.

0.2.3 (2018-12-29)

  • Check for the presence of the QUANDL_API_SF0_KEY or the QUANDL_API_SF1_KEY environment variable depending on which database the user is requesting to use.

0.3.0 (2019-09-12)

  • Refactored by using and manipulating the pandas dataframe as it’a returned from quandl/Sharadar. The dates are rows and the columns are the “observations” ie the revenue, income etc. The dataframe is transposed prior to writing to excel so that the data is in the typically viewed format of dates as columns and the observations as rows.

0.3.1 (2019-11-11)

  • Added some metrics favored by Kenneth J Marshall, author of “Good Stocks Cheap: Value investing with confidence for a lifetime of Stock Market Outperformance”
