Why is Vistar Amar falling/rising?

As of 17-Jul, Vistar Amar Ltd's stock price is currently at 129.70, reflecting an increase of 0.7 (0.54%). The stock has been gaining momentum recently, having outperformed its sector by 0.87% today and achieving a consecutive gain over the last three days with a total return of 4.98%. In terms of performance relative to benchmarks, Vistar Amar has shown a positive trend with a 1-week return of +2.17% compared to the Sensex's -1.12%, and a year-to-date return of +7.81% against the Sensex's +5.27%. However, despite these short-term gains, the company is facing significant challenges, including operating losses and a weak long-term fundamental strength, with net sales and profits declining sharply over the last six months.
Broader Market Context: The recent rise in Vistar Amar's stock price contrasts with the broader market, where the Sensex has experienced a decline. While the stock has shown positive short-term returns, it has underperformed over the longer term, with a 1-year return of -22.34% compared to the Sensex's +1.91%. This underperformance is compounded by the company's negative EBITDA and substantial losses, indicating that while there may be short-term investor interest reflected in rising participation and liquidity, the overall outlook remains risky due to the company's financial struggles and historical valuation concerns.
