The stock has been on an upward trend, gaining for the last four consecutive days and achieving an 8.1% return over the past week. It has outperformed its sector by 4.44% today. Additionally, the stock's delivery volume has significantly increased by 228.16% compared to the 5-day average, indicating rising investor participation.

In the broader market context, Tasty Dairy's short-term performance of 8.1% over the past week significantly outpaces the Sensex, which has only risen by 1.77% in the same period. This suggests that while the stock is currently experiencing a rebound, it has still underperformed relative to the benchmark over longer time frames, including a 1-year return of -30.23% compared to the Sensex's slight gain of 0.12%. The stock's current liquidity is adequate for trading, as it represents 2% of the 5-day average traded value, which may contribute to its recent price stability amidst broader market fluctuations.
