What this filing cannot show
A 13F is a partial picture. Here is the part that is missing.
It lists long positions in US-listed stocks and options only. Not short positions, cash, ordinary bonds, anything listed only abroad, anything private, or anything bought and sold inside the quarter.
What is a 13F?
A quarterly SEC filing where large investment managers list the long positions in US-listed stocks and options they held at the end of the quarter. It is a snapshot, filed up to 45 days after that date.
Why is this list weeks old?
Managers have 45 days after each quarter ends to file, and most of the funds we track file on the last permitted day. So the newest list still describes where the fund stood weeks ago, and the market has moved since.
What does “behaves like” mean?
How many equal-sized positions would be exactly this concentrated. Ten positions of the same size behave like 10. Ten positions where one holds most of the money behave like fewer than 2. It is 1 divided by the sum of each position’s squared share of the total.
Why are two lines sometimes the same company?
Each line is one security as the manager filed it. Two share classes of one company, or a company’s stock and its convertible notes, are separate lines in the filing, and they stay separate here.
