## Analyzing Trade Volume: Key Insights

Volume of trade measures the total number of shares or contracts transacted for a specified security during a specified time period. It includes the total number of shares transacted between a buyer and seller during a transaction. When securities are more actively traded, their trade volume is high, and when securities are less actively traded, their trade volume is low.

> Volume is usually highest at the market's open and close, and at the week's start and end.

## The Mechanics of Trade Volume

Each market exchange tracks its trading volume and provides volume data. The volumes of trade numbers are reported as often as once an hour throughout the current trading day. These hourly reported [trade volumes are estimates](https://www.investopedia.com/articles/active-trading/052015/simple-way-read-intraday-volume.asp). End-of-day trade volume reports are also estimates. Final actual figures are reported the following day.

Investors may also follow a security’s tick volume, or the number of changes in a contract's price, as a surrogate for trade volume since prices tend to change more frequently with a higher volume of trade.

Volume tells investors about the market's activity and liquidity. Higher trade volumes for specified security mean higher [liquidity](https://www.investopedia.com/terms/l/liquidity.asp), better order execution, and a more active market for connecting a buyer and seller. When investors are unsure about the [stock market](https://www.investopedia.com/terms/s/stockmarket.asp), futures trading volumes rise, making options and futures trade more actively. Volume overall tends to be higher near the market's opening and closing times, and on Mondays and Fridays. It tends to be lower at lunchtime and before a holiday.

## Important Considerations in Trade Volume Analysis

Recently, high-frequency traders and index funds have played a big role in U.S. trading volumes. A [2017 JPMorgan study](https://www.cnbc.com/2017/06/13/death-of-the-human-investor-just-10-percent-of-trading-is-regular-stock-picking-jpmorgan-estimates.html) found that passive investors like ETFs and quantitative accounts made up 60% of trading volumes, while fundamental discretionary traders contributed only 10%.

## How Traders Utilize Trade Volume

Traders use various trading factors in technical analysis. Trade volume is [one of the simplest technical factors](https://www.investopedia.com/articles/trading/03/102203.asp) analyzed by traders when considering market trades. During big price changes, trade volume matters because high volumes can signal specific trading catalysts. High volumes associated with directional changes in price can also help to reinforce support for the value of a security.

[Volume levels](https://www.investopedia.com/articles/active-trading/091514/essential-strategies-trading-volume.asp) can also help traders decide on specified times for a transaction. Traders follow the average daily trading volume of a security over short-term and longer-term periods when making decisions on trade timing. Traders can also use several technical analysis indicators that incorporate volume. The [Securities and Exchange Commission](https://www.investopedia.com/terms/s/sec.asp) (SEC) regulates the sale of securities by traders. According to [Rule 144](https://www.investopedia.com/terms/s/sec.asp), sellers cannot make security sales exceeding 1% of [outstanding shares](https://www.investopedia.com/ask/answers/05/sharestradedoutstanding.asp) of the same class being sold.

## Practical Example: Evaluating Trade Volume

Suppose a market consists of two traders, trader 1 and trader 2. The first trader buys 500 shares of stock ABC and sells 250 shares of XYZ. The other trader sells those 500 shares and buys the 250 shares of stock XYZ to the first trader. The total volume of trade in the market is 750 (500 shares of ABC + 250 XYZ shares). This is because we do not double-count the volume—when trader 1 buys 500 ABC shares from trader 2, only 500 shares are counted. Likewise, only 250 shares of XYZ would be recorded on the volume tally.

## The Bottom Line

The volume of trade plays a crucial role in financial markets, highlighting the total number of shares or contracts exchanged during a set period. Higher trading volumes typically indicate more liquidity and better order execution, making them attractive for investors and traders. Understanding trade volume helps to gauge market activity, with professional investors often leveraging volume insights for technical analysis and timing strategies.

While high-frequency trading and index funds contribute significantly to today’s market volumes, investors can still use trade volume data to make informed decisions about their investment strategies.
