Gap Down
A gap down happens when a stock opens below its previous close, often showing selling pressure or a negative sentiment shift.
Start the lessonIntroduction
A price fall at the open
A gap down is when a stock opens lower than its previous closing price. This creates a visible downward gap on the chart and often points to selling pressure or a negative change in sentiment.
The short answer
A gap down shows a sharp shift in sentiment at the open, but it can also become a short-lived reaction if buyers step in later.
Why it matters
It can reveal fast selling pressure
Weak sentiment
A gap down often means sellers are active right away and are not waiting for a gradual move lower.
Trend risk
It can be a signal that a downtrend is strengthening—especially if the move continues with volume.
Opportunity check
Some traders look for oversold conditions or support areas, but not every gap down is a good long-term entry.
Simple example
Compare the open with the previous close
Previous close: ₹120. Opening price: ₹111. This is a downward gap of 7.50%.
Common mistakes
A gap down is a clue, not a certainty
Assuming all gap downs keep falling
Some gap-downs reverse because traders step in to buy after a sharp move.
Ignoring market context
A gap down during a strong broad-market rally may be less significant than it looks.
Forgetting volume
Many gap-downs are more meaningful when they happen with heavy participation.
Using it alone
Risk management is still essential when the move is sharp and fast.
