Skill positioning
This skill is used to explain why a stock opens high or low, and whether such a gap represents expectation realization, expectation reinforcement, or overheated sentiment. The focus is not on describing the opening price itself, but on clearly explaining the expectation gap behind the gap, and highlighting the risks and verification points most likely to appear after the open.
Execution process
Step 1: Confirm the gap background
First clarify the background in which the gap occurs:
- Whether there are overnight announcements, earnings reports, policies, overseas映射, or sector positive/negative news
- Whether it is a stock-specific gap or a sector-wide gap
- Whether the current stock price is at a low, middle, or high level
Step 2: Determine the nature of the gap
Classify the gap into several more diagnostically meaningful categories:
- Event-driven gap
- Sentiment-reinforcement gap
- Catch-up rally/catch-up decline gap
- Technical-position-triggered gap
- Emotional high/low open without obvious new driver
Step 3: Explain the market expectation gap
Organize the judgment around “why it is not a flat open”:
- What the market has already priced in in advance
- What has not yet been fully priced in
- Whether the gap size has already exhausted the subsequent space
- What type of capital divergence is most likely to appear after the open
Step 4: Assess gap quality
Key judgments:
- Whether the gap is supported by solid events
- Whether the gap direction is consistent with the medium-term structure
- Whether the gap position is close to strong resistance or strong support
- If the high open is too large, whether there is realization pressure
- If the low open is too deep, whether emotional mispricing may occur
Step 5: Provide a post-open observation framework
Provide specific observation points:
- For a strong gap, watch follow-through and pullback performance
- For a weak gap, watch the speed of gap fill and the strength of the rebound
- If it is an emotional gap, guard against a high open low close or a low open selloff
Step 6: Integrate into a gap interpretation result
The final output should focus on “reason for the gap, credibility, and key post-open observations,” without showing the internal inference process.

IV. Key Points to Watch After the Open
- Strong confirmation signal: {what to watch}
- Weakening signal: {what to watch}
- One-sentence conclusion for now: {whether it is worth continuing to track}
Quality requirements
- The core of the interpretation is the expectation gap, not a mechanical description of the size of the gap up or gap down.
- A gap judgment must combine position and background; conclusions cannot be drawn from structure alone.
- If the event information is insufficient to support a large gap, the risk of sentiment exhaustion must be clearly flagged.
- Make every effort to distinguish between a "strong gap" and a "bull trap gap."
- The output should help users quickly grasp the verification points after the open.
