Why is Vistar Amar falling/rising?

As of 04-Sep, Vistar Amar Ltd's stock price is currently at 128.00, reflecting a decrease of 5.8, or 4.33%. Today's price summary indicates that the stock has underperformed its sector by 4.74%, opening with a loss of 2.47% and reaching an intraday low of Rs 127.1. Although the stock has shown a positive return of 1.19% over the past week, it has declined by 2.29% in the last month and has a significant drop of 19.63% over the past year. The company recently reported positive quarterly results after two consecutive negative quarters, with its highest PBDIT, PBT, and PAT figures, which could have provided some support. However, the stock's long-term fundamentals are weak, evidenced by a -33.00% CAGR growth in operating profits and a negative return on equity, leading to its classification as having a very expensive valuation relative to peers.
In the broader market context, the Sensex has shown a modest gain of 0.80% over the past week, while Vistar Amar Ltd has outperformed this benchmark slightly in the short term. However, the stock has consistently underperformed against the benchmark over the last three years, with a notable decline in profits of 118.6% over the past year. This consistent underperformance, coupled with the stock's recent trend reversal after four days of gains, suggests that investor sentiment may be shifting negatively despite recent positive results. The rising investor participation noted in the delivery volume may indicate some interest, but the overall liquidity and performance metrics suggest caution among investors.
