Will be interesting to see if the "mystery financial stock" is revealed and if more Apple sales.


According to the SEC, 13F filings are "due 45 days following the end of each fiscal quarter from institutional investment managers". That would mean it is tonight, and is for the 1st quarter, so we shouldn't find out anything new about the Apple sales - we should expect them to report holding 789.6 million shares at the end of the quarter already revealed on p.9 of Q1 report: Apple stake $135.4 billion (closing price March 31st: $171.48; 135,400m/$171.48=789.596m)

As for the mystery stock, at quarter end, the cost basis of the equity securities was $103,753m, down from $109,416m at year end. We know that Berkshire sold about 118m shares of Apple with a cost basis of about $35, so that would account for a drop of about $4.1b in the cost basis. And at the end of 2022, ther cost basis of the equity securities was $131,610, so it's hard to see how there could be any big new equity acquisition hiding in there. For some reason, Berkshire wants to keep the new acquisition secret, but it can't be very big, at least not in the first quarter, and that's what the 13F will be reporting.

Sorry to be such a wet blanket!
