Investment methodology refers to the process and techniques used by investors to analyze assets and make investment decisions. With the development of financial markets, various investment methodologies have emerged and evolved over time. Choosing an appropriate investment methodology is crucial for investors to achieve their financial goals and optimize risk-adjusted returns. This article provides an overview of major investment methodologies including fundamental analysis, technical analysis, quantitative analysis, behavioral finance, modern portfolio theory, and passive investing. There will be an in-depth examination of the core concepts, strengths and weaknesses behind each methodology, which serves as an important framework for investors to understand investment philosophy and craft optimal portfolios.

Fundamental Analysis Examines Intrinsic Value
Fundamental analysis is a traditional methodology focusing on using real data about a company’s business and financial performance to determine its intrinsic value. Fundamental investors believe stock prices gravitate towards company intrinsic value in the long run. Key tools in fundamental analysis include financial statement analysis, industry analysis, economic analysis and valuation models like DCF. The strength of fundamental analysis lies in its emphasis on business fundamentals over market volatility, which promotes making investment decisions based on facts. However, estimating intrinsic value involves subjective judgments and the convergence to fair value can take a long time. Fundamental analysis requires rigorous research and its effectiveness relies heavily on the analytical skills of investors.
Technical Analysis Studies Market Psychology
In contrast to fundamental analysis, technical analysis uses historical price and volume patterns to predict future price movements. Technicians believe asset prices move in trends dictated by supply and demand. Common technical analysis tools include trendlines, support/resistance levels, technical indicators (e.g. moving averages) and chart patterns. The main advantage of technical analysis is its applicability across different asset classes and timeframes. However, critics argue the predictive power of chart patterns is questionable and prone to data mining bias. Technical analysis is also criticized for its lack of consideration of underlying business fundamentals.
Quantitative Analysis Leverages Statistical Models
Quantitative analysis involves using advanced statistical and mathematical models to identify mispriced assets and exploit anomalies. Quants may use stochastic calculus, machine learning algorithms and big data analysis to model asset returns and construct optimal portfolios. The rigorous quantification process aims to eliminate human emotions and behavioral biases in investing. However, quantitative models rely heavily on historical data which may not apply well in new market regimes. There are also model risk and overoptimization pitfalls to consider. Quantitative analysis complements rather than substitutes for fundamental research and prudent portfolio management.
Behavioral Finance Examines Human Biases
Pioneered by psychologists Daniel Kahneman and Amos Tversky, behavioral finance studies how cognitive biases and emotions influence investors’ decisions. Key biases include overconfidence, anchoring, herding behavior and prospect theory biases like loss aversion. Behavioral finance provides explanations for market anomalies challenging the Efficient Market Hypothesis. However, directly translating behavioral finance insights into investment strategies can be difficult. The field is also limited by the lack of consensus on biases and prospect theory’s descriptive nature rather than normative prescriptions.
Modern Portfolio Theory Focuses on Diversification
Modern portfolio theory (MPT) is credited to Harry Markowitz for his work on diversification and quantification of portfolio risk-return tradeoff. MPT uses mathematical models to construct optimal portfolios of risky assets that maximize returns for a given level of risk. Key concepts include efficient frontier, correlation, beta and Sharpe ratio. MPT transformed asset allocation and risk management practices in the industry. Nonetheless, MPT has strict assumptions like normally distributed returns and perfect liquidity which are often violated in reality. The theory is also static in nature and does not adapt well to changing market conditions and investor circumstances.
Passive Investing Trusts Efficiency of Markets
Passive investing means accepting market returns with minimal active trading. Instead of stock picking, passive investors use index funds and ETFs to achieve broad diversification at low fees. They have faith that markets are efficient enough such that trying to beat the market is futile. Passive investing has gained tremendous popularity due to its simplicity, low costs and empirical evidence that many active managers underperform market benchmarks. However, markets are not completely efficient and indexing can result in overconcentration in mega-cap stocks. Savvy investors prudently combine passive and active approaches to invest successfully.
There is no universally superior methodology in investing. Astute investors understand the merits and limitations behind each approach and thoughtfully blend them based on investment philosophy, skillset and portfolio goals. Continuous learning and keeping an open mindset are key to developing sound investment principles and processes.
