Price gaps — what they are and how to interpret them on the Polish market

What is a price gap?

A price gap is a break in the price chart where no trading occurred. It appears when the opening price of a given day differs significantly from the closing price of the previous day.

• Gap up — opening higher than previous day's close (positive signal)
• Gap down — opening lower than previous day's close (negative signal)

Quick Answer

A price gap is a break in the price chart where no trading occurred, appearing when a day's opening price differs significantly from the previous close. A gap up opens higher (positive signal) and a gap down opens lower (negative signal). Gaps are usually driven by overnight news — earnings, NBP decisions or geopolitical events — and come in four types: common, breakaway, runaway and exhaustion. The saying "gaps always close" holds for most but not all (breakaway gaps can stay open for years). For long-term buy-and-hold ETF investors they should not drive decisions. This is educational, not investment advice.

Why do price gaps occur?

Gaps most often appear due to:

1. Financial results — company publishes results after session, market reacts at opening
2. Macroeconomic news — NBP decision on interest rates, inflation data
3. Geopolitical events — conflicts, elections, crises
4. Analyst recommendations — upgrade/downgrade of company

Types of price gaps

Common gap

Small gap appearing in normal trading. Usually closes quickly (price returns to pre-gap level). Little analytical significance.

Breakaway gap

Appears when breaking out of price formation (e.g., consolidation). Signals the beginning of a new trend. Usually doesn't close quickly.

Runaway gap

Occurs during a strong trend — confirms its strength. Appears in the middle of price movement.

Exhaustion gap

Appears at the end of a trend. Last surge before reversal. Often closes within a few sessions.

Do gaps always close?

A popular stock market saying states that "gaps always close". In practice most gaps close sooner or later, but:

• Breakaway gaps can remain open for months or years
• "Gap closing" has no set timeframe — it can take a day or a decade

Significance for long-term investors

If you invest in ETFs and hold long-term (buy & hold), price gaps should not influence your decisions. It's a technical analysis tool, mainly useful for short-term traders.

FAQ

What is a price gap on the stock market?

A price gap is a visible break in the price chart where no trades took place at certain price levels. It typically appears between one session's close and the next session's open, often driven by news released outside trading hours.

What is the difference between a gap up and a gap down?

A gap up occurs when the opening price is meaningfully higher than the previous close, often interpreted as bullish enthusiasm. A gap down is the opposite, signalling negative news or sentiment between sessions.

Do price gaps always get filled?

A common saying is that gaps always close, and many do, but there is no guarantee or fixed timeframe. Breakaway gaps marking the start of a strong trend can remain unfilled for months or years.

Are gaps useful for long-term investors?

For buy-and-hold investors in broad ETFs, individual gaps usually carry little practical importance. They are mainly a tool used in short-term technical analysis and intraday trading strategies.

Can gaps be predicted in advance?

Not reliably. Most gaps are caused by overnight news, earnings releases or macro events whose exact market reaction is unknown beforehand. Treating gap-based predictions as certainty is risky, and this content is educational, not investment advice.
