What is Gap Up and Gap Down in Trading?

Last Updated: 29 Aug 2025

Gaps in stock market trading appear when there is sharp rise or fall in the price of the stock and when there is no occurrence of the trading activity. The reasons for gap creation can be a positive news release by the company, change in the trade analyst view, buying or selling pressure among traders, public announcements of the company’s profit, among others.

Typically, there are two types of gaps in stock trading:

• Full gap-up
• Full gap-down
• Partial gap-up
• Partial gap -down

But what is gap up and gap down in stock market? Let’s find out.

What is Gap-up?

When the price of a financial instrument opens higher than the previous day’s price, it is gap-up.

What is Gap-down?

So, what does gap down mean in stocks? When the price of a financial instrument opens lower than the previous trading day it is gap-down. Gap-downs occur when there is a change in investor sentiment.

What is Partial Gap-up?

A partial gap-up in the stock market occurs when there is a rise in the opening prices, but the price is not higher than the previous high price.

What is Partial Gap-down?

A partial gap down in the stock market occurs when the opening price is below the previous closing price, but not below the previous day’s low.

Types of Gaps in the Stock Market

Gaps are commonly split into four categories:

• Breakaway gaps: These gaps occur at the end of the share’s price pattern and is a signal to a new trend’s beginning.
• Exhaustion gap: This gap comes at the final leg of a price pattern and is an indicator of a final attempt to reach the new high or lows in pricing.
• Common gap: This is a simple representation that shows the area of the price gap.
• Continuation gap: It occurs in the middle of a stock’s price pattern and indicates a common belief of a group of buyers or sellers in the future direction of the stock.

Factors affecting Stock to Gap Up or Gap Down

There are many reasons why a stock may open at a significantly higher or lower price level than its last closing level. They are:

• Company news: News like good earnings, new product release, mergers, or a change in the management can bring about a gap up. Bad news, like disappointing earnings or some legal issues, can lead to a gap down market.
• Economic indicators: Inflation reports, employment numbers, GDP growth or interest rate announcements can sway investor attitudes and create gaps.
• International market trends: Trends in foreign markets can influence opening rates in India.
• Sector events: News on a whole sector, such as policy shifts or commodity price fluctuations, can drive associated stocks higher or lower.
• Market attitude: Steep price movements due to intense buying or selling pressures at market open, based on fear or strong buying interest.
• After-hours trading: Changes in prices in pre-market or post-market hours due to news or events may lead to a gap on the next day’s opening.

Gap Strategies in the Stock Market

There are several ways traders try to profit from gaps in stock prices. If you are looking for a gap-up and down strategy, here are a few suggestions for you:

• Buying on a supported gap – Purchasing when a gap on the opening day is backed by strong technical or fundamental factors, such as a company’s positive financial report.
• Trading in low-liquidity situations – Investing in assets like certain currencies with low liquidity at the start of a price trend, expecting the trend to continue in a favourable direction.
• Fading the gap – Taking positions in the opposite direction of the gap when the high or low point of the stock appears fixed, often based on technical analysis.
• Waiting out early volatility – In India, the first minutes after the pre-opening session can be highly volatile. Risk-averse traders often wait and watch the market before entering trades.
• Quick profit-taking by experienced traders – Seasoned traders may enter early, relying on their market perception to capture short-term gains from gaps.

Things to Note When Gap-Trading

• Once a stock starts to fill a gap, it will not stop, as there will be little or no support or resistance in the market.
• The continuation gap and exhaustion gap are very different, so the trader has to make sure of the gap he is going to follow.
• Take note of the volume of stocks as high volume occurs in a breakaway gap, and low volume occurs in an exhaustion gap.
• Individual traders are often the ones to decide with the flow of the market, whereas institutional investors will ride the tide to see how it benefits their portfolio.
• When trading in gap, it is prudent to study and analyse the trend before trading. Once a trader understands the workings of the gap, it is easier to get high returns.
