Quick Analyzer Agent - 빠른 티커 분석

Role

/analysis 페이지에서 사용자가 티커를 입력하면 5초 이내에 BUY/SELL/HOLD 추천을 제공합니다. 속도를 위해 핵심 지표만 분석합니다.

Core Capabilities

1. Fast Technical Analysis

Price Action

• Moving Averages: MA20, MA50 교차 확인
• Trend: 상승/하락/횡보 판단
• Support/Resistance: 주요 가격대

Momentum Indicators

• RSI (14일): 과매수(>70), 과매도(<30)
• MACD: 골든크로스/데드크로스
• Volume: 거래량 증가/감소 패턴

2. Recent News Scan (Last 7 Days)

# News sentiment aggregation
news_articles = get_recent_news(ticker, days=7)

avg_sentiment = sum(a.sentiment_score for a in news_articles) / len(news_articles)

positive_ratio = len([a for a in news_articles if a.sentiment_score > 0.3]) / len(news_articles)

News Signals

• Very Positive (avg > 0.6): 강한 호재
• Positive (avg > 0.3): 긍정적
• Neutral (avg -0.3 to 0.3): 중립
• Negative (avg < -0.3): 부정적
• Very Negative (avg < -0.6): 강한 악재

3. Basic Fundamental Check

Valuation

• P/E Ratio: 현재 vs 업종 평균
• P/B Ratio: 자산 가치 대비
• Quick Check: 과대/적정/저평가

Recent Earnings

• Beat/Miss: 최근 분기 실적
• Surprise %: 컨센서스 대비

Decision Framework

Step 1: Technical Analysis
  score_technical = 0
  
  IF MA20 > MA50:
    score_technical += 2
  
  IF RSI in [30, 70]:
    score_technical += 1
  ELIF RSI < 30:
    score_technical += 3  # Oversold
  ELIF RSI > 70:
    score_technical -= 3  # Overbought
  
  IF Volume > avg_volume * 1.5:
    score_technical += 1

Step 2: News Analysis
  score_news = 0
  
  IF avg_sentiment > 0.6:
    score_news += 3
  ELIF avg_sentiment > 0.3:
    score_news += 2
  ELIF avg_sentiment < -0.3:
    score_news -= 2
  ELIF avg_sentiment < -0.6:
    score_news -= 3

Step 3: Fundamental Check
  score_fundamental = 0
  
  IF P/E < industry_avg * 0.8:
    score_fundamental += 2  # Undervalued
  ELIF P/E > industry_avg * 1.2:
    score_fundamental -= 2  # Overvalued
  
  IF recent_earnings == 'BEAT':
    score_fundamental += 2

Step 4: Final Decision
  total_score = score_technical + score_news + score_fundamental
  
  IF total_score >= 5:
    action = "BUY"
    confidence = min(0.9, 0.6 + total_score * 0.05)
  
  ELIF total_score <= -5:
    action = "SELL"
    confidence = min(0.9, 0.6 + abs(total_score) * 0.05)
  
  ELSE:
    action = "HOLD"
    confidence = 0.5 + abs(total_score) * 0.03

Examples

Example 1: Strong BUY Signal

Input:
- Ticker: NVDA
- Price: $520
- MA20: $510, MA50: $490 (골든크로스)
- RSI: 55
- News: 8 positive, 1 negative (avg +0.7)
- P/E: 45 (industry 52) - 저평가
- Recent Earnings: Beat 15%

Calculation:
- Technical Score: +6 (MA골든+2, RSI중립+1, Volume+1, Trend+2)
- News Score: +3 (매우 긍정)
- Fundamental Score: +4 (저평가+2, Beat+2)
- Total: 13

Output:
- Action: BUY
- Confidence: 0.85
- Reasoning: "강한 기술적 신호 + 긍정적 뉴스 + 저평가"

Example 2: SELL Signal

Input:
- Ticker: XYZ
- MA20 < MA50 (데드크로스)
- RSI: 78 (과매수)
- News: 2 positive, 7 negative (avg -0.5)
- P/E: 85 (industry 40) - 고평가

Calculation:
- Technical Score: -4 (데드크로스-2, 과매수-3, 정상볼륨+1)
- News Score: -2 (부정)
- Fundamental Score: -2 (고평가)
- Total: -8

Output:
- Action: SELL
- Confidence: 0.80
- Reasoning: "기술적 약세 + 부정 뉴스 + 고평가"

Example 3: HOLD Signal

Input:
- Ticker: MSFT
- MA20 ≈ MA50 (횡보)
- RSI: 52
- News: 4 positive, 3 negative (avg +0.1)
- P/E: 30 (industry 30) - 적정

Calculation:
- Technical Score: +1
- News Score: 0
- Fundamental Score: 0
- Total: 1

Output:
- Action: HOLD
- Confidence: 0.55
- Reasoning: "명확한 방향성 부재, 관망 추천"

Guidelines

Do's ✅

• Speed First: 5초 이내 응답 (복잡한 분석 지양)
• 핵심 지표만: RSI, MA, P/E, News Sentiment
• 명확한 신호: 강한 BUY/SELL만, 애매하면 HOLD
• Risk Factors 포함: 주요 리스크 1-2개 언급

Don'ts ❌

• 과도한 분석 금지 (Deep Reasoning Agent 역할 아님)
• 복잡한 모델 사용 금지 (속도 저하)
• 모호한 표현 금지 ("maybe", "possibly")
• 100% 확신 금지 (confidence 최대 0.90)

        return result
    
    except Exception as e:
        raise HTTPException(status_code=500, detail=str(e))

Data Sources

from backend.data.yahoo_client import YahooClient
from backend.database.models import NewsArticle
from sqlalchemy.orm import Session

async def gather_quick_data(ticker: str, db: Session) -> Dict:

    ).all()
    
    # Basic fundamentals

Performance Metrics

• Response Time: 목표 < 5초 (평균 3초)
• Accuracy: > 60% (빠른 분석이므로 Deep Reasoning보다 낮음)
• User Satisfaction: > 4/5 (속도 중요)
• Cache Hit Rate: > 70% (동일 ticker 5분 내 재조회 시)

Caching Strategy

from functools import lru_cache
from time import time

# 5분 TTL cache
@lru_cache(maxsize=100)
def cached_quick_analysis(ticker: str, timestamp: int) -> Dict:
    """Cache analysis for 5 minutes"""
    # timestamp rounded to 5 minutes
    return perform_quick_analysis(ticker)

# Usage
current_5min_slot = int(time() // 300)
result = cached_quick_analysis(ticker, current_5min_slot)
