What Is Volume in Stock Market? (Simple Explanation)
At its heart, volume in stock market gives us a view on the total no of shares (or contracts in terms of F&O) exchanged between buyers and sellers during a particular given span- usually in a day.
- Example: If 500,000 shares of Infosys has been exchanged today between buyers and sellers, that’s a trading volume of 500,000.
Think of volume as the “crowd size” at a cricket match—more people means more excitement. In the market, more trades mean greater attention, action, and liquidity.
Volume Meaning in Stock Market: Why Should You Care?
Many beginners ask, what is volume in stock market, and wonder why experts obsess over it. Here are clear reasons:
- Confirms Price Moves: If prices soar with heavy volume, it proves a genuine rally. Low-volume spikes may fizzle out.
- Surfaces Investor Interest: When volume spikes in unexpected sudden manner, it signals a wave of new entry of buyers or sellers.
- Affecting Buying & Selling: High-volume stocks are easier to buy or sell quickly, often at prices closer to what one wants.
- Uncovers Market Mood: Sudden rise or decrease in volume often depicts changing market sentiment—optimism, panic, or uncertainty.
In summary, volume is not just a number. It’s the market’s way of shouting what’s really happening.
Trading Volume: Beyond the Basics
Trading volume usually sits as a colored bar graph below stock price charts. Each bar represents action in that time period (minute, hour, day). Green bars point to buying activity, red show selling. High bars equal a busy crowd; low bars mean the market is sleepy.
Volume’s importance grows as markets become more volatile. It adds a crucial “truth detector” to price moves, especially when news or rumors swirl.
How to Read Trading Volume Like a Pro
1.The Basics:
- Daily volume: Total shares traded and exchanged in a single day.
- Hourly/weekly volume: Help detect trends beyond short bursts.
2. Noticing Changes:
- Volume Spikes: Watch for sudden tall bars on one’s chart, often signalling a sign of news or big move.
- Comparing to Average Volume: A good starting point is to check today’s volume against the average of the past few days or weeks. If today’s numbers are significantly higher, this could indicate something significant is happening.
3. Volume Over Time:
Spot rising or falling volume across weeks or months—are more investors paying attention, or losing interest?
Trading Volume Analysis: Turning Numbers Into Smarter Trades
Trading volume analysis means looking for patterns and combining volume with price to spot real moves versus fake-outs.
1. Price and Volume Move Together?
Price goes up + Volume goes up: Strong buying momentum, potential lasting rally.
Price goes down + Volume goes up: Real selling pressure, strong downtrend.
Price changes on low volume: Not as trustworthy—could be a brief blip.
2. Volume Surges
Huge volume at a price peak could mean all buyers have bought—possible reversal.
Massive volume at a price bottom can suggest panic selling and a chance for a bounce.
3. Confirmation on Breakouts
When a stock finally blasts through an old resistance level, verify the breakout with a volume spike. If the move is on low volume, be cautious.
4. Divergence Signals
If price keeps rising but volume falls, the rally may run out of steam soon.
