Public Float
Public float is shares available to ordinary trading — outstanding minus restricted, insider, and sometimes strategic blocks.
Definition
Public Float refers to outstanding minus restricted, insider, and sometimes strategic blocks. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
Equity risk premia compress or expand with earnings paths and factor regimes. When outstanding minus restricted, insider, and sometimes strategic blocks shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what public float is saying. If outstanding minus restricted, insider, and sometimes strategic blocks moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Separate index beta from residual; know the sector and factor loadings of the claim. Prefer a short written null hypothesis for Public Float: what would falsify the current reading in the next window?
