Investment Methodologies

The analytical tools and frameworks professionals use to evaluate opportunities and manage risk. Understanding the methods helps you evaluate advice.

Comparing Analytical Approaches

Different methodologies suit different investment styles and time horizons. There's no universally "correct" approach.

Fundamental Analysis

Focus on intrinsic business value

  • Evaluates financial statements, earnings, cash flow
  • Considers competitive positioning and industry dynamics
  • Assesses management quality and corporate governance
  • Best suited for long-term value investing
  • Requires significant research time and expertise
  • Market may take years to recognize undervaluation

The Practical Reality

Most successful investors blend approaches. Fundamental analysis identifies what to buy; technical analysis can help with timing. Neither works perfectly—markets are simply too complex for any single methodology to capture all relevant information. The key is understanding each tool's strengths and limitations rather than treating any approach as gospel.

Pattern-Based Interpretation

Markets exhibit recurring patterns—not because of some mystical force, but because human psychology remains consistent across generations. Fear and greed create predictable behaviors that show up in price charts.

However, recognizing patterns is far easier in hindsight than in real-time. The same chart formation that preceded a major rally in one instance may precede a crash in another. Context matters enormously.

Trend Identification Accuracy 65%
Reversal Pattern Reliability 45%
Breakout Confirmation Rate 55%
Mean Reversion Signal Success 70%

Trend Following

Riding established momentum until clear signs of exhaustion. Works best in strongly trending markets.

Mean Reversion

Betting that extreme moves will correct back toward average levels. Requires patience and risk management.

Breakout Trading

Entering when price escapes established ranges. High failure rate compensated by occasional large wins.

Range Trading

Buying at support, selling at resistance within defined channels. Works until the range breaks.

Multi-Layer Risk Decoding

Risk isn't a single number. It's a complex, multi-dimensional concept that manifests differently across asset classes, time horizons, and market conditions.

Systematic Risk

Market-wide risk that affects all securities. Cannot be eliminated through diversification—when markets crash, nearly everything falls together. Factors include economic recessions, interest rate changes, geopolitical events, and pandemic-level disruptions. The only protection is reducing overall exposure or using hedging instruments.

Idiosyncratic Risk

Company or sector-specific risk that can be diversified away. A single company's scandal doesn't affect unrelated holdings. This is why broad index funds are popular—they automatically provide diversification.

Liquidity Risk

The risk of being unable to sell when you need to, or being forced to accept unfavorable prices. Smaller stocks and alternative investments carry higher liquidity risk.

Currency Risk

Particularly relevant for South African investors. Offshore investments gain or lose value not just from asset performance but from Rand movements against foreign currencies.

Inflation Risk

The silent wealth destroyer. Returns that look positive in nominal terms may be negative after accounting for inflation. Conservative cash positions feel safe but guarantee purchasing power erosion over time.

Concentration Risk

Having too much exposure to any single position, sector, or theme. Feels comfortable during good times, devastating when the concentrated bet goes wrong. Position sizing matters.

Logical Assessment Models

Structured approaches to evaluating investments help remove emotional bias and ensure consistent analysis.

The Present Value Principle

Discounted Cash Flow (DCF) analysis attempts to determine what future earnings are worth today. A rand received next year is worth less than a rand today because you could invest today's rand and earn returns. DCF models project future cash flows and discount them back to present value.

  • Anchors valuation to actual business cash generation
  • Forces explicit assumptions about growth and risk
  • Provides a specific target value for comparison

Limitations to Consider

DCF models are only as good as their inputs. Small changes in growth rate or discount rate assumptions create massive changes in calculated value. The false precision of a specific number can create overconfidence. Professional analysts using DCF often disagree widely on the same company.

  • Highly sensitive to assumption changes
  • Difficult to forecast cash flows beyond a few years
  • Provides false sense of mathematical certainty

Comparing Against Peers

Relative valuation compares metrics like Price-to-Earnings (P/E), Price-to-Book (P/B), or Enterprise Value to EBITDA across similar companies. If a company trades at 10x earnings while competitors trade at 15x, it might be undervalued—or there might be good reasons for the discount.

P/E Ratio

Price divided by earnings. Higher ratios suggest growth expectations; lower ratios may indicate value or problems.

P/B Ratio

Price divided by book value. Useful for asset-heavy businesses and financial institutions.

EV/EBITDA

Enterprise value divided by operating earnings. Allows comparison regardless of capital structure.

Decomposing Returns

Factor analysis breaks down portfolio performance into exposure to various systematic factors. Academic research has identified several factors that historically explain returns beyond the overall market.

Size Factor: Smaller companies have historically outperformed larger ones over long periods, though with higher volatility.
Value Factor: Stocks with low price-to-fundamentals ratios have tended to outperform growth stocks over long horizons.
Momentum Factor: Assets that have performed well recently tend to continue performing well in the short term.
Quality Factor: Companies with high profitability, stable earnings, and low debt tend to deliver superior risk-adjusted returns.

Planning for Multiple Futures

Nobody knows what will happen. Scenario modeling acknowledges this uncertainty by evaluating investments under different potential future states. Rather than predicting, it prepares.

Bull Case

Economic growth exceeds expectations, company executes flawlessly, margins expand. What's the upside potential?

Base Case

Things proceed roughly as expected. Reasonable growth, normal competitive pressures, no major surprises. Most likely outcome.

Bear Case

Economy weakens, execution stumbles, competition intensifies. How bad could things get? Can you tolerate this outcome?
