Why is Valiant Laborato falling/rising?

As of 13-Jun, Valiant Laboratories Ltd is experiencing a price increase, currently at 118.80, reflecting a change of 0.8 or 0.68% upward. The stock has shown strong performance recently, with a 10.41% increase over the past week and a 14.34% rise over the past month, significantly outperforming the Sensex, which has declined by 1.30% and remained nearly flat over the same period. Today's price summary indicates that Valiant Laboratories is trading above its moving averages across various time frames, and there has been a notable increase in investor participation, with delivery volume rising by 25.85% compared to the 5-day average. Additionally, positive financial results, including a higher profit after tax and record net sales, alongside increased institutional investor participation, have contributed to the stock's upward momentum.
However, despite these positive short-term indicators, the company faces significant long-term challenges. The average return on equity is at 0%, and the company has experienced a concerning decline in net sales and operating profit over the past five years. Furthermore, the stock has a negative EBITDA and has consistently underperformed against the benchmark over the last three years, with a substantial annual return decline of 19.48%. This combination of weak long-term fundamentals and recent positive performance creates a complex picture for investors, highlighting both potential growth opportunities and underlying risks.
