A ruby interface for S.E.C. 13F Data. There is a lot of great finance and investing data that is available for free, but few developer tools that let us interact with the data outside of commercial platforms. This library aims to remedy a small piece of this by providing a robust API to search and retrieve investment holdings data of institutional investors through 13F Reports. What is a 13F Report? Please visit this S.E.C. webpage for a full description.
This library is meant to serve a lightweight API which developers can enhance via a persistence layer and/or UI in their own applications.
At this time, I am sure there are a number of edge cases the gem does not handle. Also it only imports 13F's submitted as XML files, which only goes back to 2013. It is a low priority for myself to robustly parse the text files provided before this time.
Add this line to your application's Gemfile:
gem 'thirteen_f'And then execute:
$ bundle install
Or install it yourself as:
$ gem install thirteen_f
search = ThirteenF::Search.new('Berkshire Hathaway')
search.get_results
result = search.results.first
result.get_entity
entity = result.entitycik_number = '0001061768'
entity = ThirteenF::Entity.from_cik cik_number
entity.most_recent_filing
entity.get_most_recent_positions
entity.most_recent_positions # returns positions from the most recent 13F filing
entity.cik # type: String | ex: "0001067983"
entity.name # type: String | ex: "BERKSHIRE HATHAWAY INC"
entity.state_or_country # type: String | ex: "NE"filing = entity.filings.first
filing.entity

# time of the period of the report
filing.index_url # type: String

positions = ThirteenF::Position.from_xml_url(xml_url)
position = filing.positions.first
position.filing
position.name_of_issuer # type: String | ex: "EBAY INC"
position.title_of_class # type: String | ex: "COM"

position.shares_or_principal_amount_type # type: String | ex: "SH"
position.put_or_call # type: String or nil | ex: "PUT"
position.investment_discretion # type: String | ex: "DFND"
position.other_managers # type: String or nil | ex: "1,4,11"
position.voting_authority # type: Hash | ex: { sole: 19994970, shared: 0, none: 0 }After checking out the repo, run bin/setup to install dependencies. Then, run
rake test to run the tests. You can also run bin/console for an interactive
prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To
release a new version, update the version number in version.rb, and then run
bundle exec rake release, which will create a git tag for the version, push
git commits and tags, and push the .gem file to
rubygems.org.
