Why is Vistar Amar falling/rising?

As of 09-Sep, Vistar Amar Ltd's stock price is currently at Rs 128.80, reflecting an increase of Rs 3.15 or 2.51%. The stock has shown a positive performance today, outperforming its sector by 1.96%, and reached an intraday high of Rs 130, marking a 3.46% rise. Over the past month, the stock has gained 2.59%, although it has underperformed the benchmark Sensex, which rose by 1.56%. The company recently reported positive quarterly results after two consecutive negative quarters, with the highest PBDIT, PBT, and PAT figures recorded. However, the stock also faces challenges, including a significant long-term fundamental weakness indicated by a -33.00% CAGR growth in operating profits and a negative return on equity.
In the broader market context, while Vistar Amar Ltd has shown a positive short-term return, it has consistently underperformed against the benchmark over the last three years, with a one-year return of -20.42% compared to the Sensex's slight decline of -0.56%. This underperformance is compounded by the stock trading at a premium relative to its peers, despite its recent positive results. The liquidity of the stock appears adequate, with a notable increase in delivery volume, suggesting rising investor participation, but the overall long-term outlook remains concerning due to the weak fundamentals and declining profits.
