Why is Polychem falling/rising?

As of 17-Nov, Polychem Ltd's stock price is currently at 2,239.00, reflecting an increase of 109.0, or 5.12%. The stock has been gaining for the last two days, with a total return of 5.56% during this period. It opened with a significant gain of 7.02% today and reached an intraday high of Rs 2279.5. Despite these positive movements, there has been a decline in investor participation, as indicated by a 1.27% drop in delivery volume compared to the 5-day average. The stock's performance over the past week shows a return of +3.66%, which is favorable compared to the Sensex's +1.69%, but it has underperformed year-to-date with a decline of 15.35% against the Sensex's increase of 8.72%. The positive factors contributing to the stock's rise include its recent outperformance against the sector and its current trading above several moving averages, although it remains below others.
Broader Market Context: The stock's recent performance indicates a strong short-term recovery, outperforming the benchmark index in the last week. However, the year-to-date performance reveals a stark contrast, with Polychem experiencing a significant decline compared to the overall market's growth. This divergence suggests that while the stock is currently experiencing a positive momentum, it has struggled to maintain consistent performance over a longer period. The broader market context, with the Sensex showing a positive trend, may also be contributing to the stock's recent gains, as investor sentiment could be shifting favorably towards equities in general.
