The three average volume comparison tables below will assist you in detecting significant changes in an index's volume output over the mid- and long-term. For instance, assume you detect a rise in the daily average volume of 15% or more compared to the average volume levels found 30 days ago. Such an increased level of trading activity could be indicative of a shift in market sentiment. Based on these volume alerts, you could then consult our volume charts and indicators, which would allow you to develop a market outlook for the mid- and the long-term.

While S&P 500 Index (^SPX) price quotes are used to describe the S&P 500 price movement, S&P 500 volume quotes are used to describe the mood that support this price movement. Furthermore, applying only price-based technical analysis to the S&P 500 reveals only half of the picture. Only a combined price and volume technical analysis of the S&P 500 can give real picture of the S&P 500's trend.
