Why is Colinz Labs falling/rising?

As of 15-Jul, Colinz Laboratories Ltd's stock price is rising, currently at Rs 44.29, reflecting an increase of 2.1 (4.98%). The stock has shown a strong performance today, outperforming its sector by 3.73% and has been on a consecutive gain streak for the last four days, accumulating a total return of 14.62% during this period. Despite this positive short-term movement, the stock has experienced significant declines over the past month and year, with returns of -20.14% and -37.09% respectively. The company has a weak long-term fundamental strength, evidenced by a -2.96% CAGR growth in net sales over the last five years and a low return on equity of 4.40%, which indicates low profitability per unit of shareholders' funds.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark, as it has gained 12.35% over the past week while the Sensex has declined by 1.36%. However, the stock's long-term performance remains concerning, with a significant underperformance against the BSE500 over the last three years, one year, and three months. The stock is trading at a discount compared to its peers' average historical valuations, but the weak fundamentals and falling investor participation, as indicated by a 36.85% drop in delivery volume, suggest that the recent rise may not be sustainable in the long run.
