Unlocking the Power of Up Volume: The Secret to Identifying Bull Markets

Discover the significance of up volume in stock trading and learn how it can signal potential bullish trends. Understand the vital role of Positive and Negative Volume Indexes (PVI and NVI) in analyzing trading volume.

Unlocking the Power of Up Volume: The Secret to Identifying Bull Markets

Up volume is generally defined as an increase in the trading volume of shares for a market or specific security that leads to an increase in its value. In contrast, down volume represents a scenario where high trading volume accompanies a decrease in value.

Key Insights

  • Up Volume: Identifies environments where rising prices coincide with increased trading activity.
  • Indication of Bull Market: Often signals a potential shift toward a rally or bullish sentiment in the market.
  • Positive Volume Index (PVI): Helps track up volume to confirm if a price rise indicates a longer-term sentiment shift.

Up volume shines in bullish markets when security prices rise alongside an increase in volume. Often referred to as “up on volume,” this phenomenon can be shaped by various factors, resulting in diverse impacts.

Real-World Application

On a day characterized by up volume, an index’s value will trade higher as trading volume increases. This pattern is consistent even in individual stocks. For example, a stock experiencing an up volume day would show a price increase, closing higher than the previous day’s close.

Volume embodies the total number of transacted shares and can escalate following the release of significant public information about a security.

Noise traders—individuals making high-volume trades based on market sentiment and trends—often trigger up volume trading days, especially after unexpected good news.

Both technical analysts and institutional investors closely monitor a stock’s volume. Spikes often signify impactful market catalysts. Many believe volume can indicate impending price breakouts, whether bullish or bearish.

Positive and Negative Volume Indexes (PVI and NVI)

Introduced by Paul Dysart in the 1930s and gaining prominence in the 1970s, Positive and Negative Volume Indexes (PVI and NVI) help investors grasp market trading volume effects.


  • Positive Volume Index (PVI): When current volume exceeds the previous day’s,
PVI = Previous PVI + [(Today's Closing Price - Yesterday's Closing Price) / Yesterday's Closing Price] x Previous PVI

If current volume is lower, PVI remains unchanged.

  • Negative Volume Index (NVI): When current volume is less than the previous day’s,
NVI = Previous NVI + [(Today's Closing Price - Yesterday's Closing Price) / Yesterday's Closing Price] x Previous NVI

If current volume is higher, NVI remains unchanged.

These indexes provide crucial insights into price movements in relation to trading volume. In an up volume trend, PVI tends to elevate as the volume ascends. Investors looking to capitalize on bullish up volume trading could use PVI to identify potential price signals.

By understanding and leveraging up volume, traders and investors can better navigate and anticipate movements within the market, potentially leading to more informed and profitable trading decisions.
