Why is Polylink Poly. falling/rising?

As of 14-Jul, Polylink Polymers (India) Ltd is currently priced at 26.63, reflecting an increase of 0.16 or 0.6%. The stock has shown a positive trend recently, gaining for three consecutive days with a total return of 2.58% during this period. However, despite this short-term gain, the stock has underperformed in the longer term, with a year-to-date decline of 10.94% and a one-year return of -12.60%. The company has an attractive valuation with a return on equity (ROE) of 7.2 and a price-to-book value of 2, indicating it is trading at a discount compared to its peers. Nonetheless, the stock's fundamentals are weak, as evidenced by a low average ROE of 4.83% and a significant drop in profit after tax in the latest quarter.
In the broader market context, Polylink's recent performance has outpaced the sector by 0.47%, while the benchmark Sensex has declined by 1.42% over the past week. Despite this outperformance, the stock's long-term trajectory remains concerning, with a three-year return of -1.19% compared to the Sensex's 53.99% gain. The stock's liquidity is adequate, but a notable decrease in delivery volume suggests waning investor interest. Overall, while there are some positive indicators in the short term, the stock's long-term fundamentals and recent performance relative to the broader market raise concerns about its sustainability.
