Why is Valiant Laborato falling/rising?

As of 04-Jul, Valiant Laboratories Ltd is experiencing a price increase, currently at Rs 117.70, reflecting a rise of 1.95 or 1.68%. The stock has shown positive momentum, gaining 5.42% over the last three days and outperforming its sector by 1.17% today. It has also touched an intraday high of Rs 118.95. However, despite these short-term gains, the stock has a concerning long-term performance, with a significant decline in net sales and operating profit over the past five years. Positive factors contributing to the recent rise include higher net sales and profit after tax in the latest quarter, along with increased participation from institutional investors, which may indicate growing confidence in the company's fundamentals.
In the broader market context, Valiant Laboratories has outperformed the Sensex in the short term, with a 1-week return of +2.04% compared to the benchmark's -0.74%. However, the stock's long-term performance remains weak, with a 1-year return of -15.02%, indicating consistent underperformance against the benchmark over the last three years. This juxtaposition of short-term gains against a backdrop of long-term challenges suggests that while the stock is currently rising, there are significant risks and fundamental weaknesses that could impact its future performance.
