Why is Chemo Pharma Lab falling/rising?

As of 15-Oct, Chemo Pharma Laboratories Ltd's stock price is currently at 125.50, reflecting a slight increase of 0.1 (0.08%). The stock has shown a positive performance recently, gaining 8.1% over the last two days, although it has underperformed in the past week with a decline of 6.93%. Year-to-date, the stock has risen by 14.26%, and over the past year, it has experienced a substantial increase of 71.00%. However, there is a notable decline in investor participation, with delivery volume dropping by 97.39% against the five-day average, which may indicate reduced trading interest. Unfortunately, there is no information available regarding positive or negative factors that could further explain the stock's recent movement.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has gained 1.02% over the past week. While Chemo Pharma Laboratories Ltd has outperformed its sector by 0.8% today, its short-term decline of 6.93% over the past week stands in stark contrast to the benchmark's positive movement. Despite the stock's strong year-to-date and yearly returns, the recent drop in delivery volume suggests caution among investors, which could be influencing the stock's price stability in the short term.
