Why is Vivanta Indust. falling/rising?

As of 24-Sep, Vivanta Industries Ltd is currently priced at 2.52, reflecting a decline of 0.01 (-0.4%). The stock has underperformed the sector today by 0.33%, and it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has decreased by 1.95%, and it has shown a significant decline of 31.89% year-to-date.

In the broader market context, the Sensex has decreased by 1.18% over the past week, which suggests that the overall market sentiment is slightly negative. However, Vivanta's performance has been notably worse, with a year-over-year return of -34.03%, compared to the Sensex's decline of only 3.77%. This stark contrast highlights the stock's underperformance not just in the short term but also over the longer term, as it has lagged behind the benchmark indices in various time frames, further contributing to the negative sentiment surrounding the stock.
