Investment Strategy Framework
1. Investment Goals & Time Horizon
Define clear objectives: growth, income, or balanced approach. Your time horizon determines risk tolerance - longer periods allow for more volatility and growth-focused investments.

Understand your risk tolerance and capacity. Diversify across sectors, company sizes, and potentially international markets. Never invest more than you can afford to lose.
3. Research & Analysis Process
Analyze company fundamentals, industry trends, and economic factors. Use multiple valuation methods and consider both quantitative metrics and qualitative factors.
4. Portfolio Management & Monitoring
Regularly review and rebalance your portfolio. Monitor performance against benchmarks, track dividend payments, and adjust strategy based on changing circumstances.

Frequently Asked Questions
How do you calculate stock returns?
Stock returns are calculated as: (Current Value - Initial Investment + Dividends) ÷ Initial Investment × 100%. This includes both capital gains/losses and dividend income. For annualized returns, use: ((1 + Total Return)^(1/Years) - 1) × 100%.
What's the difference between total return and price return?
Price return only considers capital gains/losses from stock price changes. Total return includes both price changes AND dividend payments reinvested. Total return provides a more complete picture of investment performance and is the standard metric for comparing investments.
How are stock dividends taxed?
Qualified dividends are taxed at favorable capital gains rates (0%, 15%, or 20% depending on income). Non-qualified dividends are taxed as ordinary income. Dividends from most U.S. corporations and qualified foreign corporations held for 60+ days are considered qualified.
What is dividend yield and why does it matter?
Dividend yield = Annual Dividend per Share ÷ Current Stock Price × 100%. It shows the annual dividend income as a percentage of your investment. Higher yields can provide steady income but may indicate slower growth or higher risk. Compare yields within the same industry.
Should I reinvest dividends automatically?
Dividend reinvestment (DRIP) can accelerate wealth building through compounding, often with no fees. However, you still owe taxes on dividends received. Consider your need for current income, tax situation, and whether you want to maintain your current allocation or diversify elsewhere.
How do I calculate my cost basis for taxes?
Cost basis = Purchase Price + Commissions + Fees. For multiple purchases, use average cost basis or specific identification method. Keep detailed records of all purchases, including dates, prices, and fees. Reinvested dividends increase your cost basis and should be tracked separately.
What factors affect stock performance?
Key factors include: company fundamentals (earnings, revenue growth), industry trends, economic conditions, market sentiment, interest rates, geopolitical events, and company-specific news. Beta measures volatility relative to the overall market (1.0 = market volatility).
