🧠 1. What is Stock Market Analysis?

Stock market analysis is the evaluation of securities to make investment decisions.

🧭 Two Primary Types:

Type Focus Tools
Fundamental Analysis Business value, earnings, financial health Balance sheets, income statements, ratios
Technical Analysis Price movement and patterns Charts, indicators, trading volume

🧾 2. Fundamental Analysis (FA)

Fundamental analysts believe the intrinsic value of a stock is determined by a company’s financial performance.

🔍 Core Components:

Element Metric/Example
📈 Revenue Growth YoY or QoQ revenue increase
💰 Earnings EPS (Earnings Per Share)
📊 Valuation Ratios P/E, P/B, PEG, EV/EBITDA
🏛️ Balance Sheet Debt-to-Equity, Current Ratio
🧑‍💼 Management Track record, founder-led companies
🌎 Macro Trends Industry performance, interest rates

📘 Example:

Apple (AAPL):
- EPS: $6.11
- P/E: 27.3 (as of 2025 Q1)
- Dividend Yield: 0.5%
- Low debt ratio and steady growth make it a long-term favorite.

📉 3. Technical Analysis (TA)

TA assumes that all information is already priced into the stock and focuses on historical price & volume.

📊 Common Tools:

Tool Description
📈 Trendlines Identify upward/downward trends
🔁 Moving Averages SMA, EMA help smooth volatility
💡 Indicators RSI, MACD, Bollinger Bands
🔲 Patterns Head & Shoulders, Flags, Triangles

📉 Example Chart:

Price
  ↑
$350 ────●───●───●───▼───▼───▼───●───▲───▲
         SMA20                     RSI oversold

Forward Tip:

Combine TA + FA for a hybrid view: Use FA to choose the stock, TA to time the entry.

🔄 4. Sentiment & News Analysis

Markets are driven by investor psychology, especially in the short term.

🔍 Factors:

  • Social media sentiment (e.g., Reddit, Twitter)
  • Economic reports (CPI, unemployment)
  • Earnings announcements
  • Analyst upgrades/downgrades

Tooling:

  • Google Trends
  • Alternative data (web traffic, satellite imagery)
  • NLP tools for earnings calls or news sentiment

📊 5. Quantitative & Algorithmic Analysis

This uses mathematical models and often powers hedge funds or robo-advisors.

Key Concepts:

Concept Description
Backtesting Testing strategies on historical data
Mean Reversion Price returns to its average over time
Momentum Buy high, sell higher
Risk Management Stop losses, max drawdowns

Example:

Python script running 10-day mean reversion strategy on S&P 500 stocks.

⚖️ 6. Risk and Portfolio Management

Analysis must be paired with portfolio allocation and risk control.

Golden Rules:

  • Diversify across sectors & geographies
  • Position sizing: Don’t risk more than 2% on a single trade
  • Use stop-losses & trailing stops
  • Consider correlation between holdings

🧰 7. Tools and Platforms

Category Tools
Charting TradingView, StockCharts, Thinkorswim
Screening Finviz, Screener.co, Yahoo Finance
Data Alpha Vantage, Quandl, Yahoo API
Trading Interactive Brokers, Robinhood, Fidelity
Python Libraries yfinance, pandas, matplotlib, ta-lib

📈 8. Real-World Workflow for a Stock Analyst

→ Deep dive into top 5 picks with FA
→ Check technical chart: trends, support/resistance
→ Read earnings call transcripts & news
→ Decide entry point, set stop-loss, buy
→ Monitor with trailing stop and news alerts

🧩 9. Common Strategies by Type

Strategy Type Description

Growth Investing FA Bet on earnings growth (e.g. Tesla, Nvidia)
Swing Trading TA Hold 2-10 days based on momentum
