To analyze the performance of a stock, you would need to conduct fundamental and technical analysis.
Fundamental analysis is a tool to measure a stock's intrinsic value by scrutinizing its fundamental factors (financial and economic). Under this, you will examine everything that may have a direct impact on the share price, ranging from macroeconomic factors like the condition of the economy, industry trends, compliance and legal matters, and the management of the company.
The main intention is to deduce a number that investors may have as a reference with the share price to determine if the share is overvalued or undervalued. On the other hand, technical analysis involves determining the future movement of the share price with the help of past data.
