Fundamental Analysis and Business Valuation
Fundamental analysis examines the business behind the stock - revenue, earnings, profit margins, competitive advantages, and industry position. Fundamental analysts study financial statements, read earnings reports, and assess management quality. They ask questions like whether the company is growing, whether it is profitable, and what it is worth compared to peers. This approach assumes that stock prices eventually reflect business value. Fundamental analysis works best for long-term investors who want to own quality businesses.
Technical Analysis and Price Patterns
Technical analysis ignores the business and focuses purely on price and volume patterns in charts. Technical analysts look for trends, support and resistance levels, moving averages, and repeating candlestick patterns. They assume that past price patterns predict future movements. This approach is popular with short-term traders who buy and sell within days or weeks. Technical analysts believe price action already reflects all known information about the business, so analyzing the business is unnecessary.
When Each Approach Has an Edge
Fundamental analysis provides advantage when investing with a multi-year horizon and wanting to identify undervalued businesses. Technical analysis works better for timing entry and exit points within a trend. Many professional investors combine both methods - use fundamental analysis to select which stocks to buy, then use technical analysis to time when to buy and sell. Short-term traders rely almost exclusively on technical analysis. Long-term buy-and-hold investors care mainly about fundamental value.
The Limitations and Risks of Each Method
Fundamental analysis assumes markets eventually become rational and prices reflect value, but this takes years and markets can stay irrational. Technical analysis ignores business quality and can lead to buying poor companies with nice charts. Neither method predicts black swan events or major economic surprises. Using only one method leaves you vulnerable to the errors unique to that method. The best investors develop skill in both areas while recognizing that markets contain randomness no analysis method can fully predict.
