Why is Tasty Dairy falling/rising?

As of 23-Sep, Tasty Dairy Specialities Ltd's stock price is flat at 8.56, with no change (0.00%). The stock has shown mixed performance recently, outperforming its sector by 1.8% today, but it has a concerning trend with a 5.31% decline over the past month and a significant 26.21% drop year-to-date. The stock's delivery volume has decreased sharply by 76.92% compared to the 5-day average, indicating falling investor participation. Additionally, the company has a negative book value and a high Debt to EBITDA ratio, which suggests weak long-term fundamental strength and low profitability, further contributing to investor caution.
In the broader market context, Tasty Dairy's short-term return of +0.94% over the past week contrasts with the Sensex, which has declined by 0.34%. However, the stock has consistently underperformed against the benchmark over the last three years, with a staggering 61.96% decline compared to the Sensex's 41.31% gain. This persistent underperformance, coupled with negative financial indicators such as a negative EBITDA and low return on equity, paints a challenging picture for the stock, leading to a cautious outlook among investors.
