Why is Tasty Dairy falling/rising?

As of 13-Jun, Tasty Dairy Specialities Ltd is experiencing a price increase, with its current price at 10.65, reflecting a change of 0.24 or 2.31% upward. The stock has shown strong performance recently, gaining 19.93% over the last seven days and outperforming its sector by 2.9% today. Despite this positive short-term momentum, the company faces significant challenges, including a negative book value and a high Debt to EBITDA ratio of -1.00 times, indicating weak long-term fundamental strength. Additionally, the company has reported a substantial decline in net sales and profit after tax, both down by 72.61% over the past nine months, which raises concerns about its profitability and ability to service debt.
In the broader market context, Tasty Dairy's recent performance contrasts sharply with the benchmark, as it has gained 14.52% over the past week while the Sensex has declined by 1.30%. However, the stock's year-to-date performance remains negative at -8.19%, while the Sensex has increased by 3.81%. This divergence highlights the stock's volatility and the potential risks associated with its negative EBITDA and low return on equity, which may deter long-term investors despite the recent price rally driven by rising investor participation and institutional holdings.
