What is Volume?
Definition
Volume is the total number of shares or contracts traded in a security during a given period, typically a single trading day. It measures the intensity of trading activity and is a key indicator of market interest, liquidity, and the strength of price movements.
Detailed Explanation
Volume represents the total shares that change hands between buyers and sellers. Average daily volume is the mean over typically 20, 50, or 90 days.
Volume confirms price movements. A price increase on high volume suggests strong buying conviction. A price increase on low volume may indicate weak participation and a potential reversal.
Volume spikes often accompany major events like earnings reports or analyst upgrades. Unusually high volume without an obvious catalyst can sometimes signal institutional positioning.
For traders, volume is essential for assessing liquidity. Stocks with low average volume can have wide bid-ask spreads. Volume is also used in technical indicators like On-Balance Volume (OBV), VWAP, and the Accumulation/Distribution line.
