Why is Deco-Mica falling/rising?

As of 16-Sep, Deco-Mica Ltd is currently priced at 75.10, reflecting a decrease of 0.9, or 1.18%. The stock has underperformed its sector today by 1.02%, and it has shown erratic trading patterns, not trading on one day out of the last twenty. The stock's performance over the past week has been notably poor, with a decline of 6.13%, while it has generated a return of -17.29% over the past year, significantly underperforming the broader market. Despite a very attractive valuation indicated by a ROCE of 10.9 and trading at a discount compared to peers, the stock's profits have fallen by 0.9%, contributing to its recent price decline.
Broader market context shows that while the Sensex has gained 1.58% over the past week, Deco-Mica's performance has been negative, highlighting a stark contrast in momentum. The company's weak long-term fundamental strength, characterized by a high Debt to EBITDA ratio of 3.40 times and a low average Return on Equity of 8.68%, suggests challenges in profitability and debt servicing. Additionally, the stock's liquidity is adequate for trading, but the significant drop in delivery volume by 61.63% against the 5-day average indicates falling investor participation, further pressuring the stock's price.
