Why is Diamond Power falling/rising?

As of 04-Sep, Diamond Power Infrastructure Ltd is experiencing a decline in its stock price, currently at Rs 141.00, which reflects a decrease of Rs 3.5 or 2.42%. Today's performance indicates that the stock has underperformed its sector by 3.35%, following a trend reversal after three consecutive days of gains. The stock touched an intraday low of Rs 140.2 and has a weighted average price indicating that more volume was traded close to this low price. Despite a significant rise in delivery volume by 43.41% against the 5-day average, the stock's longer-term performance shows a 14.62% decline over the past month and a year-to-date drop of 7.57%. Positive factors include consistent growth in net sales and profit after tax over the last seven quarters, but these are overshadowed by negative aspects such as a negative book value, high debt levels, and decreasing promoter confidence, which collectively contribute to the stock's recent downward movement.
In the broader market context, Diamond Power's short-term return of +1.04% over the past week outperformed the Sensex, which gained only 0.80%. However, the stock's longer-term performance is concerning, with a year-to-date decline of 7.57% compared to the Sensex's increase of 3.30%. The company's high debt-to-equity ratio and poor long-term growth metrics further exacerbate its risk profile, suggesting that while there may be short-term trading activity, the overall sentiment remains cautious due to fundamental weaknesses.
