Trading Volume: Analysis and Interpretation

Trading Volume

Traders usually use volume in combination with other factors like whether the price is declining or increasing, and how much volatility there is. Products, accounts and services are offered through different service models (for example, self-directed, full-service). Based on the service model, the same or similar products, accounts and services may vary in their price or fees charged to a client. Schwab does not recommend the use of technical analysis as a sole means of investment research.

A downtrend accompanied by increasing and/or above average volume implies investors have doubts about the stock, which could lead to more selling and even lower prices. During downtrends and in sideways markets, a stock’s price will occasionally run into a support level, which is where downward trends tend to weaken as buying pressure overcomes selling pressure. When the price breaks below a support level, the breakdown is generally believed to be more significant if volume is high or above average. A breakout accompanied by low volume suggests enthusiasm is lacking. An uptrend without increasing and/or above average volume suggests investor enthusiasm is limited. While the price could continue to rise, many traders who use volume analysis will nevertheless look for other candidates.

The most common timeframe to use when talking about volume in stocks is the daily volume. The average daily volume is the average number of shares traded per day over a certain period, often approximately 1 month.

Volume levels 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 (SEC) regulates the sale of securities by traders. According to Rule 144, sellers cannot make security sales exceeding 1% of outstanding shares of the same class being sold.

This result indicates that intensive trading activity coincides with the involvement of informed traders who choose to exploit their information advantage in the frequently traded stocks. Infrequently traded stocks, however, seem to have different information transmission mechanisms. The level of trading volume in a contract implies a measure of intensity or urgency in a move. Essentially if a market is rising on weak volume and weak open interest, traders may conclude that the market will fall back from the higher level sooner rather than later. To detect or conclude a trend pattern requires heavy volume, and to a lesser extent high open interest. The market also expects volumes to increase in the direction of the trend, and decrease on (temporary) pullbacks against the trend.

Volume levels are an important component of reversal patterns, particularly the head-and-shoulders pattern. For instance it is a characteristic of the head-and-shoulders to observe low volume in the “head” and high volume from the top of the pattern. The primary rule regarding volume however remains that volume must expand in the direction of the market trend.

We find this to be true across the market generally and for the most widely held securities. We also observe the average trade size has fallen in recent months, suggesting that more volume has been retail-driven and relatively less has been from other sources such as block trading. Trading Volume, or volume in trading, is the number of completed trades in a single security or across a whole market in a given time period.

Trading Volume

Investors who have high conviction about the stock in the long term might want to wait for a pullback before buying it if recent stock price gains were on low volume. In short, above average and/or increasing trading volume can signal that traders are truly committed to a price move, which you can see in Chart 1 below, where the price and volume lines are both increasing. Contrariwise, below average and/or decreasing volume can signal a lack of enthusiasm, which you can see in Chart 2, where volume is declining even as the price continues to creep higher. Trading volume can also signal when an investor should take profits and sell a security due to low activity. If there is no relationship between the trading volume and the price of a security, this signals weakness in the current trend and a possible reversal.
