Abstract

Investment analysis can be categorized into two main approaches: Technical and fundamental. Technical analysis focuses on historical price movements and trading volume to identify trends and support levels. This study utilizes Symbolic Aggregate Approximation (SAX) to analyze stock data from two major Indonesian consumer goods companies�PT. Mayora Indah, Tbk. (MYOR) and PT. Unilever Indonesia, Tbk. (UNVR). SAX provides a novel approach to technical analysis by preserving crucial characteristics of stock data while simplifying complexity. Our findings reveal distinct patterns in stock movements: Mayoras stock exhibits stronger and more stable support and resistance levels, making it a more attractive option for long-term investment. In contrast, Unilever�s stock shows weaker resistance and a slower recovery potential, suggesting limited growth prospects in the short term. These insights offer investors a structured method for comparing stocks based on trend stability and cyclical behavior. Overall, this study contributes to financial analysis by demonstrating SAX�s effectiveness in identifying investment opportunities within volatile markets while minimizing data loss.
