iShares 0-3 Month Treasury Bond ETF
The portfolio's cash allocation: liquid, productive, and waiting for a better price somewhere else.
Treasury bills maturing in under three months, the portfolio's cash allocation.
Historical view
Investment case
Role in the portfolio
This is effectively the cash allocation. It keeps capital liquid and productive while waiting for attractive opportunities during a choppy market, and can be redeployed when individual holdings or the broader market create better entry points.
Very short-dated Treasury bills carry almost no interest-rate sensitivity and no credit risk worth modeling. The trade-off is deliberate. This allocation is not expected to compound at an equity rate; it exists so a market dislocation can be acted on without selling something else on someone else's schedule.
The cost of holding it
The real cost is opportunity cost. In a rising market it lags, and its yield falls as short-term rates fall. That is the accepted price of holding the option to act.
Risks and thesis invalidation
The thesis argues the case against itself in The cost of holding it.
