Why is Sover. Diamonds falling/rising?

As of 27-Oct, Sovereign Diamonds Ltd is experiencing a price increase, with its current price at 28.46, reflecting a change of 0.33 or 1.17% upward. The stock has outperformed its sector by 0.64% today and has shown a consecutive gain over the last two days, rising 1.68% in this period. However, despite this recent uptick, the stock's performance over the past month is down by 5.89%, and it has seen significant declines year-to-date and over the past year, with losses of 59.33% and 40.51%, respectively. The stock's delivery volume has notably decreased by 73.4% against the 5-day average, indicating falling investor participation, which could be a concern for its future performance.
In the broader market context, the stock's short-term return of 0.96% over the past week has outperformed the Sensex, which has gained 0.49% in the same period. However, the stock's longer-term performance is concerning, as it has significantly underperformed the benchmark over the past month, year-to-date, and year, while it has shown strong gains over the last three and five years. The liquidity of the stock remains adequate for trading, but the declining delivery volume suggests that investor interest may be waning, which could impact future price movements.
