Examples:
Using the ``filings`` function from secedgar is the easiest way to retrieve filings.
Depending on the arguments given, secedgar will return an object that will get you
the information you want from EDGAR.
There are 4 main classes which can be returned.
- :class:`secedgar.ComboFilings` for fetching filings over multiple days
that does not fall exactly into a quarter
- :class:`secedgar.CompanyFilings` for fetching a particular
filing type for one or more companies
- :class:`secedgar.DailyFilings` for fetching all filings
from a specific date
- :class:`secedgar.QuarterlyFilings` for fetching all filings
from a specific quarter
To get all filings over a time span, you could use something like below.
.. code-block:: python
from datetime import date
from secedgar import filings, FilingType
# secedgar creates correct filing object for given arguments
# this will fetch the first 50 filings found over the time span
my_filings = filings(start_date=date(2020, 12, 10),
end_date=date(2020, 12, 15),
filing_type=FilingType.FILING_4,
user_agent="Name (email)",
count=50)
# easy access to methods shared across all 4 different filing classes
my_filings_urls = my_filings.get_urls()
my_filings.save("/path/to/directory")
To get a single filing type for one or more companies, you could use this:
.. code-block:: python
from secedgar import filings, FilingType
# similar to above, but fetches filings for specific tickers
company_filings = filings(cik_lookup=["aapl", "fb"],
filing_type=sec.FilingType.FILING_10Q,
user_agent="Name (email)")
company_filings_urls = company_filings.get_urls()
company_filings.save("/path/to/directory")
To get filings for a single day, you could use something like this:
.. code-block:: python
from datetime import date
from secedgar import filings
# all filings for
daily_filings = filings(start_date=date(2020, 1 ,3),
end_date=date(2020, 1, 3),
user_agent="Name (email)")
daily_filings.save("/path/to/directory")
# limit which quarterly filings to use - saves only form 4 filings
limit_to_form4 = lambda f: f.form_type.lower() == "4"
daily_filings_limited = filings(start_date=date(2020, 1 ,3),
end_date=date(2020, 1, 3),
user_agent="Name (email)",
entry_filter=limit_to_form4)
daily_filings_limited.save("/path/to/other/directory")
For getting filings from a specific quarter, the function call would look like this:
.. code-block:: python
from datetime import date
from secedgar import filings
# all quarterly filings
quarterly_filings = filings(start_date=date(2020, 1 ,1),
end_date=date(2020, 3, 31),
user_agent="Name (email)")
quarterly_filings.save("/path/to/directory")
# limit which quarterly filings to use
# saves only 10-K and 10-Q filings from quarter
limit_to_10k_10q = lambda f: f.form_type.lower() in ("10-k", "10-q")
quarterly_filings_limited = filings(start_date=date(2020, 1 ,1),
end_date=date(2020, 3, 31),
user_agent="Name (email)",
entry_filter=limit_to_10k_10q)
