How to read it
- Source and timing. Form N-MFP filings, published by the SEC as data sets, as filed. Each bar is the month’s report date (the last business day of the month). Months with only a handful of funds (amendments of an earlier month) are left out.
- Share is measured against the whole you are looking at: all holdings for the asset types, the asset’s own holdings for its parts. Yield and WAM are weighted by value, as on the snapshot. Treasuries has no lower level here; the snapshot splits it into bills and coupons.
- Other includes money funds holding shares of other funds, which makes the totals larger than the funds’ net assets by that double counting. Foreign and domestic banks are told apart by issuer name. See the snapshot for one month in detail.
