Stock In-Depth Technical Analysis Skill

Overview

This skill focuses onin-depth diagnosis of stock technicals, going beyond basic market updates to provide logical assessment based on multiple dimensions. Through comprehensive analysis of trend structure, volume-price coordination, key levels, and technical indicators, and incorporatingfree-float sizeandindustry characteristicsfor adjustment, it provides users with an objective assessment of trend strength and reference for key trading ranges.

Data Toolset (gildata-aidata)

Tool Name Core Function Key Parameters
AShareLiveQuote Real-Time Quotes and Market Capitalization Obtain current price, turnover rate, volume ratio, total market capitalization, and circulating market capitalization (to judge float size)
StockQuoteTechIndex Full Overview of Technical Indicators Obtain MA, MACD, KDJ, RSI, BOLL indicators and support/resistance level values
StockRangeQuotation Range Statistics Calculate recent highs and lows, amplitude, and turnover amount to assist in judging support and resistance
StockMultiPeriodQuote Multi-Period Resonance Compare daily/weekly/monthly trends to judge the major-level direction

Core Analysis Dimensions

1. Trend Diagnosis

  • Moving Average System：
    • Bullish/Bearish Alignment: MA5>MA10>MA20 indicates strong bullish alignment; the reverse indicates bearish alignment.
    • Trend Slope: The greater the upward divergence angle of the moving averages, the stronger the trend.
  • High-Low Structure：
    • Ascending Channel: Lows continue to rise, and highs continue to refresh.
    • Descending Channel: Highs continue to decline, and lows continue to be broken.
    • Multi-Period Resonance: The daily trend must defer to the weekly trend. If the daily chart rebounds but the weekly chart is bearish, it is regarded as a "rebound" rather than a "reversal".

2. Volume-Price Analysis

  • Volume-Price Coordination Logic：
    • Rising Volume with Rising Price: Healthy rise, with high capital recognition.
    • Rising Price with Shrinking Volume: Momentum weakens, and caution is needed against a bull trap (unless it is a highly controlled large-cap stock).
    • Falling Price with Expanding Volume: Panic selling emerges, and the trend may deteriorate.
    • Extremely Low Volume and Price: Extremely low volume often corresponds to a phased bottom.
  • Turnover Rate Interpretation (Combined with Float Size)：
    • Large-Cap Stocks (>100 billion): A turnover rate >3% is active, and >5% is extremely active.
    • Small and Mid-Cap Stocks (<20 billion): A turnover rate >7% is active, and >15% is characteristic of hot money relay buying.

3. Support and Resistance

  • Dynamic Support/Resistance：
    • Moving Average Support: MA20 (lifeline) and MA60 (decision line) are key defensive levels.
    • Bollinger Bands: The upper band is resistance, the lower band is support, and the middle band is the strength/weakness dividing line.
  • Static Support/Resistance：
    • Previous Highs/Lows: The highest/lowest price in the range.
    • Chip Dense Zone: The area of concentrated prior trading volume (estimated from the range's turnover).
  • Support-Resistance Conversion: After breaking above a resistance level, resistance becomes support; after breaking below a support level, support becomes resistance.

4. Technical Indicator Analysis (Indicators)

  • MACD: A golden cross above the zero axis is a strong buy point; top/bottom divergence is an important reversal warning signal.
  • KDJ/RSI: Used to judge short-term overbought (>80) or oversold (<20) conditions.
  • BOLL: Widening bands indicate accelerating trend changes; narrowing bands indicate consolidation.

Adjustment Logic Based on Individual Stock Characteristics

In analysis, the weighting must be adjusted based on thefree-float market cap:

  1. Large-cap blue chips/core assets (free-float market cap > 100 billion)

    • Characteristics: Stable price action, institution-dominated, high effectiveness of technical indicators.
    • Analytical Focus: Focus on MA60/MA120 long-term moving average support, ignore short-term KDJ fluctuations. For volume-price relationship, pay more attention to "moderate volume expansion".
    • Industry Attributes: Combine with industry prosperity (e.g., for banking and energy, look at dividends and macro; for technology, look at growth).

  2. Small/mid-cap/thematic stocks (free-float market cap < 20 billion)

    • Characteristics: High elasticity, dominated by hot money/sentiment, prone to extreme moves.
    • Analytical Focus: Focus on turnover rate and abnormal volume. Technical indicators tend to become distorted (numbed), so sentiment factors (e.g., consecutive limit-up height) must be considered.
    • Industry Attributes: Combine with theme热度 (e.g., AI, low-altitude economy and other hot trends).

Workflow

  1. Obtain Basic Data: Query AShareLiveQuote to get market cap, current price, and turnover rate.
  2. Obtain Technical Indicators: Query StockQuoteTechIndex to get MA, MACD, KDJ, BOLL, and support/resistance values.
  3. Obtain Range Data: Query StockRangeQuotation (last 20 days/60 days) to confirm highs/lows and trend.
  4. Comprehensive Diagnosis：
    • Determine trend direction (bullish/bearish/consolidating).
    • Evaluate the health of volume-price relationship.
    • Confirm the current stock price's position within the support/resistance network.
    • Provide differentiated interpretation based on market cap characteristics.
  5. Generate Report: Output structured diagnostic results.
