Why is Innomet Advanced falling/rising?

As of 22-Sep, Innomet Advanced Materials Ltd is experiencing a decline in its stock price, currently at 166.25, reflecting a decrease of 8.75 or 5.0%. The stock has underperformed its sector today by 6.64%, and while it is higher than the 200-day moving average, it is lower than the 5-day, 20-day, 50-day, and 100-day moving averages. Over the past week, the stock has seen a significant drop of 12.75%, and its year-to-date performance shows a decline of 5.46%. Despite a rise in investor participation, with a 25% increase in delivery volume, the overall sentiment appears negative, contributing to the stock's recent downward movement.
In the broader market context, the Sensex has shown a positive return of 0.53% over the past week, contrasting sharply with Innomet's decline. The benchmark has also outperformed the stock significantly on a year-to-date basis, with a return of 6.59% compared to Innomet's negative performance. This disparity indicates that while the market is generally favorable, Innomet is struggling to keep pace, which may be influencing investor sentiment and leading to the stock's decline.
