Why is Delta Manufact. falling/rising?

As of 25-Jul, Delta Manufacturing Ltd's stock price is currently at Rs 90.25, reflecting a decrease of Rs 4.63 or 4.88%. Today's price summary indicates that the stock opened with a loss of 3.04% and reached an intraday low of Rs 90.25. The stock has underperformed its sector by 3.47% today, with a significant drop in delivery volume, which has fallen by 98.18% compared to the 5-day average. Over the past week, the stock has declined by 6.57%, and year-to-date, it has seen a substantial drop of 17.09%. The company's weak long-term fundamentals, highlighted by operating losses and a negative EBITDA, further contribute to the stock's downward movement, alongside a high debt-to-EBITDA ratio and declining net sales.
In the broader market context, Delta Manufacturing's performance has been notably weaker compared to the benchmark, with the Sensex showing a slight decline of only 0.36% over the past week. While the stock has underperformed the benchmark in each of the last three years, it has also generated a negative return of 1.37% over the past year, contrasting sharply with the Sensex's positive return of 4.25% year-to-date. This consistent underperformance, coupled with the company's financial struggles and falling investor participation, paints a concerning picture for potential investors, reinforcing the stock's status as a strong sell.
