Why is Ucal falling/rising?

As of 22-Sep, Ucal Ltd's stock price is currently at 139.00, reflecting a decrease of 2.8, or 1.97%. The stock has been underperforming, having lost 3.47% over the last three days, and it is currently lower than the 5-day, 50-day, 100-day, and 200-day moving averages, although it remains above the 20-day moving average. Additionally, investor participation has declined significantly, with delivery volume dropping by 42.75% compared to the 5-day average. The stock has also shown a year-to-date decline of 30.83%, contrasting sharply with the Sensex, which has gained 5.15% during the same period.
In the broader market context, Ucal Ltd's short-term performance over the past week shows a return of 0.72%, which is better than the Sensex's return of 0.46%. However, the stock's longer-term performance remains concerning, with a year-over-year decline of nearly 30% compared to the Sensex's slight decrease of 2.82%. This underperformance, combined with falling investor interest and liquidity concerns, suggests that Ucal Ltd is facing significant challenges in the current market environment.
