Reductions and Exits – What Buffett is Exiting According to the Q3 2026 13F filing, no position reductions or complete exits are explicitly mentioned. The 13F form only lists holdings as of the quarter's end, without indicating changes from previous periods. Therefore, it's impossible to determine, based solely on this document, which securities were sold or reduced. Limitations of the 13F: What This Filing Doesn’t Say Several limitations should be considered when reviewing the 13F filing. First, it must be filed within 45 days after the end of the quarter, meaning the data can be up to several weeks old. Second, the 13F only reports long positions; short positions are not disclosed. Third, positions held through options, futures, or other derivatives are not included. Finally, only U.S.-listed company investments are required to be reported, with foreign investments potentially remaining invisible in this filing.
