Cuts and Exits: What Buffett is Leaving Behind

According to available information, no reductions or full exits are reported in the filing for the considered quarter.

Limitations of the 13F: What This Filing Doesn’t Say

The 13F form reflects positions on the last day of the quarter but is filed within 45 days, creating a reporting lag. It only covers long equity positions in the U.S., excluding short positions, options, futures contracts, and securities held outside the U.S. Thus, the filing does not reveal the fund’s total exposure to other asset classes or hedging strategies.
