Why is Zim Laboratories falling/rising?

As of 13-Nov, Zim Laboratories Ltd is experiencing a decline in its stock price, currently at Rs 72.67, which reflects a decrease of Rs 4.23 or 5.5%. The stock has been underperforming, having fallen consecutively for the last two days with a total decline of 6.38%. It opened the day with a significant loss of 3.42% and reached an intraday low of Rs 72.11. Additionally, the stock's delivery volume has drastically decreased by 89.76% compared to the 5-day average, indicating a drop in investor participation. Over the longer term, the stock has shown a year-to-date decline of 32.08%, which is considerably worse than the Sensex's gain of 8.11% during the same period.
In the broader market context, Zim Laboratories' short-term performance over the past week shows a modest gain of 2.60%, which is better than the Sensex's increase of 1.40%. However, this positive short-term return is overshadowed by the stock's significant long-term underperformance, particularly over the past three years, where it has plummeted by 76.82% compared to the Sensex's growth of 36.71%. This stark contrast highlights the challenges facing Zim Laboratories, as it struggles to attract investor interest and maintain liquidity in a market that is otherwise showing positive trends.
