Understanding Volume Analysis

Why Volume Matters:
  • Liquidity: High volume stocks are easier to buy/sell
  • Interest: Indicates market attention and institutional activity
  • Momentum: Volume often precedes price movements
  • News Events: Earnings, announcements drive volume spikes
  • Current Volume: Today’s trading activity
  • Average Volume: Typical daily trading volume
  • Volume Ratio: Current vs average (>2x is significant)
  • Dollar Volume: Price × Volume (institutional focus)
  • High Volume + Price Up: Strong bullish momentum
  • High Volume + Price Down: Strong bearish pressure
  • High Volume + Flat Price: Accumulation/distribution
  • Low Volume: Lack of conviction in price moves
