Why is Vinyl Chemicals falling/rising?

As of 29-Jul, Vinyl Chemicals (I) Ltd is experiencing a decline in its stock price, currently at Rs 294.00, which reflects a decrease of 1.0 (-0.34%). The stock has been underperforming, having fallen consecutively for the last four days, resulting in a total decline of 5.01% during this period. Over the past week, the stock has decreased by 4.16%, and it has also shown a significant drop of 28.12% over the past year. Despite a recent intraday high of Rs 301.25, the stock is trading below its short-term moving averages while remaining above the 100-day moving average. The company has a low debt-to-equity ratio and a fair valuation with a price-to-book value of 4.3, but it is trading at a premium compared to its peers. The stock's performance has been hindered by flat results and low domestic mutual fund interest, indicating a lack of confidence among institutional investors.
In the broader market context, Vinyl Chemicals has underperformed the Sensex, which has shown a slight decline of 1.03% over the past week, while the stock's performance has been significantly worse. The stock's year-to-date return of -14.78% starkly contrasts with the Sensex's positive return of 4.09%. This underperformance is compounded by the company's recent flat results and the lowest return on capital employed (ROCE) at 23.94%. The stock's long-term performance has also been disappointing, as it has lagged behind the BSE500 over the last three years, one year, and three months, further contributing to investor skepticism and the stock's current downward trend.
