Financial Definition of VOLUME


What It Is

Volume represents the total number of securities traded during a certain period of time.

How It Works

Volume records the number of transactions taking place during a period of time. It is a direct measure of liquidity in a market. The major exchanges report volume figures on a daily basis, both for individual securities and for the total amount of trades executed on the exchange.

For example, let's assume a buyer of stock purchases 500 shares from a seller. The volume then increases by 500 shares for that period of time.

Volume also reflects pricing momentum. When market activity -- i.e., volume -- is low, investors anticipate slower moving (or declining) prices. When market activity goes up, pricing typically moves in the same direction.

Why It Matters

Next to price, volume is likely the most closely watched indicator in technical analysis because it conveys so much information.

Technical analysts believe that volume can serve as a warning signal as to whether a stock is on the verge of breaking into upside territory (high volume) or into a downside trend (low volume). Low volume of a security, even if it's rising in price, can indicate a lack of conviction among investors. Conversely, high volume of a particular security can indicate that traders are placing their long-term confidence in the investment.

Volume is incredibly important to traders. Without volume, it becomes more difficult to buy or sell securities when you want to, and at the price you want.

History for volume

The earliest books were not like the books we read today. Instead of having pages that turn, they were written on rolls of papyrus. The Latin word for such a scroll, volumen, came from the verb volvere, meaning “to roll.” English volume came by way of French from Latin volumen. At first volume meant “scroll” or “book,” but later it came to mean “the size of a book” as well. This sense led to the more general meaning of “size” or “amount”—as in the volume of a jar or the volume of sales. From this sense came still another meaning: “loudness or intensity of sound.”
