A comprehensive guide to understanding gaps on technical charts, including their definition, the four main types, detailed examples, and in-depth analysis.
A stock gap is an area on a technical chart where an asset’s price jumps higher or lower from the previous day’s close, leaving a gap between the two price points. These gaps are significant in technical analysis as they can indicate strong market movements and potential future price directions.
Technical analysts categorize gaps into four primary types:
Common gaps typically occur in the absence of significant news and during low trading volume. They are temporary and often fill quickly, meaning the asset’s price returns to close the gap within a short period.
Breakaway gaps form at the beginning of a new trend and signify a strong price movement. They occur when an asset breaks out from a consolidation pattern or trading range, often accompanied by high volume.
Runaway gaps happen in the middle of a strong trend, reflecting sustained interest from traders. Unlike common gaps, they are less likely to fill quickly and demonstrate ongoing market momentum.
Exhaustion gaps appear near the end of a significant price trend and suggest that the current price move is nearing its conclusion. These gaps might be accompanied by a decrease in trading volume and are seen as potential reversal signals.
Consider a stock that has been trading within a range between $50 and $55 for several weeks. Suddenly, the stock price gaps up to $60 due to a positive earnings report, breaking out of its previous range.
In a sustained uptrend, a stock closing at $75 jumps to $80 the next day due to strong buying interest. This runaway gap reinforces the continuing bullish sentiment and indicates further upward movement.
Gaps occur primarily due to significant news events, earnings reports, or shifts in market sentiment that trigger substantial changes in the buying and selling behavior of traders.
While common wisdom suggests that “gaps always get filled,” this is not a universal rule. Some gaps, especially runaway gaps during strong trends, may take a long time or may never be filled.
The concept of stock gaps has been integral to technical analysis since the early 20th century. Notable traders like Charles Dow and later, technical analysts like W.D. Gann and Richard Wyckoff, emphasized the importance of gaps in predicting market movements.
While both terms describe significant price movements, a “gap” specifically refers to the void between the closing price of one day and the opening price of the next, whereas a “jump” can describe any sudden price increase.
A “spike” describes a sharp price movement within the same trading day, often due to a temporary surge in buying or selling pressure, while a “gap” spans across sequential trading days.
