Average daily dollar volume, 30 days (ADV 30d)
The average value of shares traded per session over the last 30 calendar days.
It says how much of a position the market could absorb in a day without the holder bidding against themselves.
How it is computed here
Mean of close x shares traded, over the sessions the market was open
Today's market price against the latest available fundamentals. From our own daily bars, on the sessions the market was open. The window and the sessions it holds are stated beside the figure. Filed under risk. Higher is the stronger reading, other things equal.
No published threshold exists for this figure, so this page prints none. Read it against the company's own history and its peers instead.
When it misleads
- Sessions with no trade are counted; weekend and holiday bars are dropped.
- A mean is carried by one block trade on a thin stock; the 90-day median is not.
