Why is Menon Pistons falling/rising?

As of 15-Sep, Menon Pistons Ltd is experiencing a decline in its stock price, currently at Rs 68.06, which reflects a decrease of Rs 1.11 or 1.6%. Today's performance indicates that the stock has underperformed its sector by 2.76%, with an intraday low of Rs 67.2, marking a drop of 2.85%. The stock's recent returns show a 1-week gain of 1.60% and a 1-month increase of 6.18%, but it has a year-to-date decline of 5.00% and a significant 1-year drop of 18.47%. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 37.42% against the 5-day average, suggesting reduced interest among investors.
Broader Market Context: In comparison to the benchmark Sensex, which has risen by 1.24% over the past week and 1.47% over the past month, Menon Pistons' short-term performance is relatively stronger, yet the overall year-to-date performance shows a stark contrast with the Sensex's gain of 4.67%. This divergence indicates that while the stock has had some positive short-term movements, it is struggling to maintain momentum in the face of broader market gains. The liquidity of the stock remains adequate for trading, but the overall negative sentiment reflected in its recent price movements and declining investor participation may be contributing to its current downward trend.
