VWAP — the institutional benchmark
The volume-weighted average price: what it is, who watches it, and how it behaves.
VWAP — the volume-weighted average price — is the average price of every share traded so far today, weighted by size. It resets each session and answers one question exactly: what has the average participant paid today? Price above VWAP: the average buyer is winning. Below: underwater.
Why it matters: who is anchored to it
VWAP is not folklore — it is the execution benchmark institutions are graded against. A fund working a large buy order all day wants an average fill at or below VWAP, so execution algorithms slow down above it and work harder below it. That mechanical behavior — buyers fading in below the line, patient above — is what gives VWAP its gravitational feel and makes it self-reinforcing: it matters because the biggest participants are paid to care.
Two modes: magnet and rail
| Rotational day | Trend day | |
|---|---|---|
| Price vs VWAP | crosses it repeatedly | holds one side all session |
| VWAP acts as | magnet — reversion target | rail — dynamic support/resistance |
| The play | fade extensions back toward it | use pullbacks to it as continuation entries |
| Rhymes with | positive gamma | negative gamma |
