Traders and investors in the Indian financial markets routinely use various fundamental and technical indicators to formulate strategies and make trading decisions. One such indicator that is used to analyse the prices of securities is VWAP.
If you are unsure what VWAP is and how it is used, this article will give you all the answers you want about this unique technical indicator.
What is VWAP in the stock market -VWAP full form and meaning
The full form of VWAP is Volume-Weighted Average Price. It is a technical indicator that lets you know the average trading price of security for a particular period — after it is adjusted for the trading volume. Since the VWAP indicator accounts for the volume of securities traded, it is considered to be a more accurate measure of the average trading price than solely price-based indicators.
What is a Volume-Weighted Average Price?
Now that you know the meaning of VWAP in the stock market, you may want to gain a deeper understanding of the indicator.
The Volume-Weighted Average Price is a dynamic indicator that changes as the units of the security continue to be bought and sold. By adjusting the average price based on the trading volume, the VWAP indicator smooths out price fluctuations over time and evens out the trading noise created. In other words, it provides traders and investors with a mean volume-adjusted price value.
The VWAP in the stock market is generally represented as a single line on the price chart of a security. Both intraday and short-term traders commonly use it to identify trends. These traders enter trading positions depending on how the security’s price interacts with the Volume-Weighted Average Price.
How is the VWAP used?
The Volume-Weighted Average Price is useful for traders in multiple ways. One popular use of VWAP in the decision-making process is to use the metric as an instrument for trend confirmation and creating trading strategies based on it. For example, a security may be believed to be undervalued if its value is below the VWAP. On the other hand, it may be overvalued if its trading price is above the VWAP.
VWAP also influences trading strategies. For instance, a stock’s trading price being above the VWAP encourages investors to take long positions in the market. On the other hand, a stock trading below the VWAP encourages short positions and market exit.
Furthermore, VWAP also influences decisions for institutional investors such as mutual funds. They use VWAP to minimise their impact on the market when buying or selling stocks. Their goal is to buy stocks below the VWAP or sell above it, helping keep prices closer to the average.
How do you calculate the Volume Weighted Average Price?
You can calculate the Volume Weighted Average Price for an asset using the following VWAP indicator formula.
| VWAP = (Cumulative Price x Cumulative Trading Volume) ÷ Cumulative Trading Volume |
Here, the cumulative price refers to the total value of all of the prices at which trades were executed during a specific period. The cumulative trading volume refers to the total value of all the trading volumes of trades executed during the said period.
Although it is possible to carry out VWAP calculations for any security using the above formula, you don’t always have to do it manually. Today, most new-age stockbrokers display the VWAP for securities on their trading portals. Alternatively, you can also find the metric on the website of stock exchanges.
How to interpret a VWAP indicator
Monitoring the VWAP indicator can give you valuable insights into the price trend of a security. For instance, if the price of an asset is above its VWAP line, it is considered to be in bullish territory. On the other hand, if the price is below the VWAP line, the asset is said to be in bearish territory.
You can use an appropriate VWAP trading strategy depending on whether the asset is in bullish or bearish territory. Additionally, the VWAP may also indicate potential future price movements.
Why is VWAP important?
VWAP combines price and trading volume, giving traders a reference point to understand price direction and market activity. It can support technical analysis by providing context for potential entry and exit decisions.
Assessing market direction:
- Bullish indication: Price above VWAP may suggest stronger buying pressure.
- Bearish indication: Price below VWAP may indicate stronger selling pressure.
Supporting entry and exit decisions:
- Entry analysis: Traders may compare the current price with VWAP before entering a position.
- Exit analysis: VWAP can also provide a reference when reviewing potential exit levels.
Considering trading volume:
- Volume weighting: VWAP considers both price and trading volume.
- Better context: Higher-volume price levels have greater influence on the calculation than lower-volume levels.
How to trade and interpret the VWAP indicator?
Here’s a quick overview of how to use a VWAP indicator. The most common trading technique used involves taking positions based on VWAP line crossovers.
For example, you already know that if the price is below VWAP, the asset is considered bearish; if it is above, it is considered bullish. If the asset cuts across its VWAP line from below and moves past it, this may be viewed as a bullish reversal. You could consider entering into a long position in the asset to benefit from a potential price rise.
On the other hand, if the price of the asset cuts its VWAP line from above, it may indicate a potential bearish reversal. In this case, you may short the asset for some possible gains.
The VWAP indicator is also useful for institutional investors like mutual funds, which often purchase or sell securities in large quantities. Normally, such large orders can impact the market significantly. However, with the help of the VWAP indicator, these investors can purchase or sell securities without creating much of a market impact.
For instance, if an institutional investor wishes to buy 1 lakh shares of a company, they would break up the large order into multiple smaller orders with prices at or near the VWAP. This increases the chances of their orders being executed and leaves a very minimal impact on the market.
Difference between VWAP and simple moving average
While a simple moving average and VWAP are both important tools in technical analysis as they measure the average price of a stock over time, they differ in one key aspect. The simple moving average measures the average stock price by only considering the prices in a given timeframe. Improving upon this, the VWAP accounts for the price of the security as well as the volume of trade at different price levels. It assigns a higher value to price points with higher trade volume and vice versa. Owing to this, the VWAP is an improvement on the simple moving average and is highly relied upon by investors to calculate more accurate averages for stocks.
What are the limitations of VWAP
- Resets daily: VWAP is generally calculated for a single trading session and resets when a new trading day begins.
- Historical indicator: VWAP reflects past price and volume data, so it does not predict future price movements.
- Needs context: Use VWAP with other technical indicators rather than relying on it alone.
- Changes during the day: VWAP is more responsive early in the session and becomes less sensitive as more trading data accumulates.
Conclusion
This sums up what the VWAP means and how you can use it to trade in the financial markets. Before using the indicator, you should know that it is not advisable to rely only on the Volume Weighted Average Price for trading decisions. Instead, you can use it along with other technical indicators or candlestick patterns. This way, you can not only avoid false trading signals but also increase the chances of success of your trading decisions.
