What Is Up Volume?

"Up volume" generally refers to an increase in the volume of shares traded in either a market or security that leads to an increase in value. Up volume can be contrasted with down volume.

Understanding Up Volume

Up volume occurs in bullish markets when security prices are rising with increased volume in the market. Up volume may also be referred to as up on volume. Overall, volume can be influenced by a number of faꦓctors and may have various effects.

On an up volume trading da💝y, an index’s value would trade higher in conjunction with an increase in its trading volume. The same concept occurs in a single security. For example, an up volume stock day for a single stock would show a price trading higher and ultimately closing higher than the previous day’s close.

Volume is the total number of shares that are transacted. Volume can be influenced by𒅌 a number of factors and is typically higher following the release of public information about a security.

If the news was unanticipated it can boost trading from both institutional and retail investors as the price gains. Noise traders will contribute to high-volume trading days since they follow trends and trade heavily on sentiment.

Many technical analysts believe that volume can also be a signal of a price breakout in a bullish or bearish direction.

PVI and NVI

The Positive and Negative Volume Indexes (PVI and NVI) were first developed by Paul Dysart in the 1930s to help investors discern some of🅰 the effects of market trading volume. PVI and NVI then became more popular in the 1970s after the calculations were expanded to individual securities.

PVI: If current volume is greater than the previous day's volume, PVI = Previous PVI + {ဣ[(Today's Closing Price-Yesterday's Closing Price)/Yesterday's Closing Price)] x Previous PVI}. If current volume is lower than the previous da𓆉y's volume, PVI is unchanged.

NVI: If current volume is less than the previous day’s volume, NVI = Previous NVI + {[(Today's Closing Price-Yesterday's Closing Price)/Yesterday's Closing Price)] x Previous NVI}. If current volume is higher than 𒈔the previous day's volume, NVI is unchanged.

These index values provide insight on how prices are fluctuating with trading volume. In an up volume trend, PVI would trend higher as volume increased. Thus, investors seeking to profit on bullish up volume trading could ൲use the PVI as one indicator for potential price signals.
