Stock Volume is the number of shares of a security that are traded during a specified period of time. It tells you how many shares changed hands between buyers and sellers.
Stock volume represents the volume of a single stock (single public company); It can be used to evaluate the flow of money to or from a single stock (security), to analyze trading activity in this stock, to define the liquidity of a particular stock and, by using volume and price analysis together, to define the current sentiment, as well as to predict changes in this feeling and the price trend of this stock.
Stock volume can be used to analyze a single stock for the purpose of trading this stock or options or futures of this stock. The volume of a single stock does not reflect the health of the economy and cannot be used to evaluate an industry or stock market mood.
Index Volume represents the total volume of all stocks included in a particular index. Therefore, the volume of the S&P 500 index is the total volume of all 500 stocks that are included in the S&P 500 index basket. Thus, index volume represents the trading activity in a particular market sector or particular group of stocks that are covered by this index.
Index volume helps to define the money flow and sentiment in specific market sectors. An analysis of volume and price of indexes helps you to evaluate a particular industry and to predict changes in the mood of this industry. In addition, some indexes may be used to define the health of the entire economy (S&P 500 and DJI indexes, for instance).

With index volume-based technical analysis, you will know when it's the right time to buy or sell your security. It doesn't matter if you are not trading an index-derived security, because most securities follow the trend of the major indexes. You may use index volume to analyze an index trend and predict possible changes in the sentiment and trend of this index for the purpose of trading Exchange-Traded Funds (ETFs) on this index, options and futures on this index, index tracking mutual funds, options and futures on the ETFs of this index and stock from this index basket. As you see, index analysis opens a far wider potential for trading than does a single stock analysis.
For instance, an S&P 500 index volume analysis could be, and should be, used to trade:
