Sector Analysis - The technology sector is expected to continue its momentum, while healthcare and consumer sectors are identified as key areas for long-term investment [5]. - Analysts caution that high valuations in certain sectors, particularly technology and semiconductors, may lead to profit-taking and increased market fluctuations as the year-end approaches [4][5].
