Why is Deep Diamond falling/rising?

As of 30-Jul, Deep Diamond India Ltd is experiencing a decline in its stock price, currently at 4.34, which reflects a decrease of 0.15 or 3.34%. The stock has underperformed its sector today by 3.35%, and it is trading lower than its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has seen a return of -4.41%, and it has also underperformed significantly over the last year with a return of -25.81%. The company has weak long-term fundamentals, indicated by a -3.68% CAGR growth in net sales over the last five years and a poor EBIT to interest ratio of -0.16, which suggests challenges in servicing its debt. Additionally, the low return on equity of 3.94% signifies low profitability, contributing to the stock's negative performance.
In the broader market context, the stock's short-term return of -4.41% over the past week contrasts with the benchmark Sensex, which has only declined by 1.50%. This consistent underperformance against the benchmark over the last three years, along with a significant drop in stock value year-to-date at -35.03%, highlights the company's struggles relative to the overall market. Despite a 63% increase in profits over the past year, the stock's return remains negative, indicating that investor sentiment is not favorable, likely due to the company's weak fundamentals and valuation concerns.
