Managers listing MBI in Q4 2020
Share of 13F value is the position’s reported value over everything the manager reported that quarter. The share change is against Q3 2020, and only where both filings list the position. A rise in value with no rise in shares is the price, not buying.

How much of the picture this is
A 13F is a manager’s long US-listed equity book at a quarter end, filed up to 45 days later. It shows no shorts, cash, bonds or performance, and it is never today’s portfolio. Large books are listed to their largest positions, so a manager missing from this table may still hold a small position below that line. These are 95 tracked managers, not the institutional market.
