Note: Using the latest_13f_filing function will return the the latest "simplified" version of the 13F Information Table, this works well in most instances... However, there are some who may want to have a more detailed breakdown of the filing. Such as, which investment manager was responsible for investing in the security and the voting authority type granted. This can be handled with the function latest_13f_filing_detailed (below).
