Quality Factor - Based on financial and operational metrics to identify high-quality companies, which may face valuation risks during periods of high market risk appetite [13]. 7. Momentum Factor - Utilizes the trend-following theory, capitalizing on stocks that have shown strong past performance, though it may struggle in volatile markets [14]. 8. Reversal Factor - Exploits price reversal opportunities, performing well in choppy or bearish markets but underperforming in strong trends [15].
