Why is Ajanta Pharma falling/rising?

As of 18-Nov, Ajanta Pharma Ltd. is experiencing a decline in its stock price, currently at Rs 2,459.20, which reflects a decrease of Rs 44.1 or 1.76%. The stock has underperformed its sector by 1.14% today and has been on a consecutive downward trend for the last five days, resulting in a total decline of 4.59% during this period. Additionally, the stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Despite a high management efficiency indicated by a return on equity (ROE) of 21.01% and a low debt-to-equity ratio, the company has shown poor long-term growth with net sales increasing at an annual rate of only 12.85% over the last five years. The stock's valuation appears expensive with a price-to-book value of 7.1, and it has significantly underperformed the market over the past year, generating negative returns of -14.46%.
In the broader market context, while the Sensex has gained 0.96% over the past week, Ajanta Pharma's performance has been notably weaker, with a 4.59% decline in the same timeframe. The stock's year-to-date performance is also concerning, showing a decrease of 16.52% compared to the Sensex's increase of 8.36%. This stark contrast highlights the stock's struggles to keep pace with market trends, further exacerbated by flat results reported in September and a low debtors turnover ratio. The high institutional holdings at 26.44% indicate that more sophisticated investors are involved, yet the overall sentiment remains negative due to the company's lack of growth and underperformance relative to the broader market.
