A 13F does not report cash. It covers only U.S.-listed securities — cash, bonds, foreign stocks and private holdings are invisible in it, which is why Berkshire’s cash pile appears in its 10-Q and not here. What the filing does show is direction: selling more than buying means money left U.S. equities that quarter. Where it went — cash, fixed income, other markets — the form does not say.
Showing the 250 largest, which add up to 62.5% of the portfolio.
Estimated across every position in each quarter, so a single stock can be compared against the whole. Same caveat as elsewhere: a 13F reports the share count on the last day of the quarter, while dividends are paid throughout it.
