Why is Valiant Laborato falling/rising?

As of 15-Jul, Valiant Laboratories Ltd is currently priced at 115.20, reflecting an increase of 2.4 (2.13%). The stock has shown a positive performance today, outperforming its sector by 0.88% and reaching an intraday high of Rs 115.55. However, the stock has experienced a decline of 1.71% over the past week and a more significant drop of 3.03% over the last month. Despite this, there are positive indicators such as higher net sales and profit after tax in the latest quarter, alongside an increase in institutional investor participation, which may contribute to the recent upward movement. Nonetheless, the company faces challenges with weak long-term fundamentals, including a negative return on equity and a concerning decline in net sales and operating profit over the past five years.
In the broader market context, Valiant Laboratories has underperformed against the benchmark, with a year-to-date return of +4.02% compared to the Sensex's +5.67%. The stock's performance over the last year has been particularly poor, with a return of -21.58%, indicating consistent underperformance against the broader market. This trend is compounded by a significant drop in investor participation, as evidenced by a 42.98% decrease in delivery volume compared to the five-day average. While the stock's recent rise may be attributed to short-term positive results and institutional interest, the overall long-term outlook remains challenging, which could affect future price movements.
