Why is Tega Inds. falling/rising?

As of 24-Sep, Tega Industries Ltd is currently priced at 1,907.00, reflecting a decrease of 9.95 or 0.52%. The stock has been experiencing a downward trend, having fallen for the last five consecutive days, resulting in a total decline of 9.82% over the past week. Despite this recent downturn, the stock has shown positive performance over the longer term, with a year-to-date return of 21.48% and a three-year return of 241.27%. However, the stock's delivery volume has significantly decreased by 59.67% compared to the five-day average, indicating a drop in investor participation. While the company boasts high management efficiency and a low debt-to-equity ratio, these positive factors have not been sufficient to counteract the recent price decline.
In the broader market context, Tega Industries Ltd's short-term performance has been notably worse than the benchmark, with the Sensex only declining by 1.18% over the same one-week period. This stark contrast highlights the stock's underperformance relative to the market. Despite the company's strong fundamentals, including high institutional holdings and consistent returns over the past three years, the recent price movement suggests that investor sentiment may be shifting negatively, possibly due to the recent drop in trading volume and consecutive price falls.
