- Fund flow data (where institutional money is moving)
- Economic leading indicators (PMI, yield curve, employment)
- Congressional trading patterns by sector
- Earnings revision momentum by sector
Earnings Season Trading
Pre-Earnings Strategy
- Implied volatility expansion: Options get expensive before earnings
- Historical moves: Check average earnings move (e.g., NVDA moves ±8% on earnings)
- Analyst estimates: Whisper numbers often differ from consensus
- Position before: Smaller size due to binary outcome uncertainty
Post-Earnings Strategy (More Reliable)
- Gap and go: If stock gaps up on great earnings + volume, buy the continuation
- Fade the overreaction: If stock drops 5-10% on decent (not terrible) earnings, buy the oversold bounce
- Guidance matters more: Forward guidance drives longer-term moves more than past results
Earnings Calendar Approach
- Track dates: CAN SLIM investors buy leaders with strong earnings
- Cluster analysis: When multiple companies in a sector beat, signals sector strength
- Supply chain signals: Component suppliers reporting tells you about big tech earnings
Dividend Investing
Dividend Growth Investing
Focus on companies that consistently grow their dividends:- Dividend Aristocrats: S&P 500 companies with 25+ consecutive years of dividend growth
- Target yield: 2-5% current yield with 5-10% annual growth
- Payout ratio: Should be <60% (room to maintain and grow dividend)
- DRIP: Reinvest dividends to compound returns
High-Yield Strategy (Income Focus)
- REITs: Required to pay 90% of income as dividends (5-10% yield)
- MLPs: Energy infrastructure (6-9% yield)
- BDCs: Business development companies (8-12% yield)
- Preferred stocks: Fixed income-like with higher yields
Dividend Safety Checklist
- â Payout ratio below 60%
- â Consistent dividend growth (5+ years)
- â Free cash flow exceeds dividend payments
- â Low debt-to-equity ratio
- â Industry with stable cash flows
- â Avoid: High yield with declining revenue (yield trap)

Frequently Asked Questions
Frequently Asked Questions
How much money do I need to start investing in stocks?
You can start with any amount thanks to fractional shares. However, $1,000-5,000 allows proper diversification across 5-10 positions. For active trading with signals, $5,000-25,000 is recommended for meaningful position sizing.
What is the difference between investing and trading?
Investing is buying and holding for months to years based on fundamental value. Trading is buying and selling over hours to weeks based on technical setups and signals. Both can be profitable â choose based on your time availability and temperament.
Should I buy individual stocks or ETFs?
Start with ETFs (like SPY, QQQ) for diversified exposure with less risk. Add individual stocks as you develop stock selection skills. A good mix: 60-70% ETFs for core holdings, 30-40% individual stocks for alpha generation.
How do I identify good stocks to buy?
Look for: accelerating revenue and earnings growth, expanding margins, strong free cash flow, reasonable valuation (PEG < 2), insider buying, and positive analyst revisions. Combine fundamental screening with technical entry timing using signals.
What is the best time to buy stocks?
Statistically: market pullbacks of 5-10% within uptrends, after earnings beats with guidance raises, and during sector rotation into undervalued sectors. Use signals for specific entry timing rather than trying to time the overall market.
