Why is Gratex Industrie falling/rising?

As of 23-Sep, Gratex Industries Ltd is experiencing a price increase, currently at 20.25, reflecting a change of 0.36 or 1.81% upward. The stock has shown a positive performance today, outperforming its sector by 3.39%, and has been on a gaining streak for the last two days, with a total return of 3.85% over the past week. However, there are concerns regarding erratic trading patterns, as the stock did not trade on two days out of the last twenty, and there has been a significant drop in delivery volume, which fell by 96.5% against the five-day average. Additionally, the company faces long-term fundamental weaknesses, including a negative CAGR growth in operating profits over the last five years and a low return on equity, which may affect investor confidence despite the recent price rise.
In the broader market context, Gratex Industries' short-term return of 3.85% over the past week contrasts with the Sensex, which has seen a decline of 0.34% in the same period. While the stock has outperformed the benchmark recently, its year-to-date performance remains negative at -22.77%, compared to the Sensex's positive return of 5.07%. This divergence suggests that while the stock is currently gaining, it is still struggling significantly in the longer term, which could be a concern for investors looking for sustainable growth.
