Rebalance of April 30, 2021
1-12 Month constituents
Every one of the 92 holdings, with the three deductions that set its weight, both prices, and its contribution to the month. The contributions add to the published return, which is what makes a level checkable rather than something to trust.
Check it yourself
- Holdings
- 92
- Weights sum to
- 100.0000%
- Contributions sum to
- +0.005912%
- Market value
- $4.33tn
Both totals are added up on this page from the rows in the table below, not read from a stored figure, a total computed somewhere you cannot see would prove nothing. The check below compares that sum against the level published on the 1-12 Month page, fetched separately.
These reconcile. The holdings below sum to +0.005912% against a published month return of +0.005912%, a difference of 5.0e-8 basis points, the published rounding rather than arithmetic. That shows this level is reproducible from these holdings; it is not a check on the prices behind them, since both sides use the same ones.
How each weight is set
Par auctioned, less what Treasury has bought back and retired, less what the Federal Reserve holds, gives the float that is actually investable. The two deductions are applied in that order rather than combined: a buyback destroys the debt, while the Federal Reserve only parks it, so merging them would restore retired par the moment quantitative tightening reversed.
