Downloads specified annual report 10K filings from the SEC's Edgar database. This program needs 2 inputs, an Excel sheet (containing tickers and company names) and a txt containing a JSON string mapping SEC CIK numbers to tickers. An example CIK dictionary is provided in this repo. Output is written in txt form for frequency analysis. To make it more legible to humans consider saving filing as docx. Debugging: the module selenium is in the experimental phase. Any bugs are best solved by running program from the site-packages directory.
