Technical Analysis involves evaluating securities by analyzing statistics generated by market activity, such as price and volume. It utilizes charts, patterns, and indicators to interpret past market behavior and predict future price trends.
Technical analysts, often referred to as “chartists,” operate on the principle that historical price movements can hint at future market trends. They analyze price patterns, market trends, and volume data and apply an array of analytical tools to aid their buy or sell decisions.
Example: A technical analyst might use a basic tool like a trend line, which displays a security’s directional trend, to decide when to enter or exit a market. If the security price breaches the trend line, it could be interpreted as a signal to buy or sell.

Technical Analysis and Fundamental Analysis are the two primary methodologies employed by traders and investors to evaluate and predict financial markets, albeit from different perspectives.
Technical Analysis concentrates on analyzing price data patterns to forecast future pricing and volume trends. It revolves around answering the “what” (what is the price doing?) and the “when” (when should I buy or sell?).
On the other hand, Fundamental Analysis investigates the “why” behind price movements. It appraises the intrinsic value of an asset, factoring in economic, financial, and other qualitative and quantitative aspects.
Each method has its pros and cons, and employing them in unison can provide a holistic view of the market.

Figura: This infographic, titled “Understanding Fundamental Analysis,” provides a comprehensive guide to the key aspects of fundamental analysis in finance. It explains how fundamental analysis involves evaluating a company’s financial statements and health, its management and competitive advantages, and its competitors and markets. It emphasizes the importance of looking beyond just the numbers and considering the overall picture of a company’s potential for growth and profitability. This visual guide is particularly useful for those interested in long-term investments and seeking to understand the intrinsic value of stocks.
