Why is Abbott India falling/rising?

As of 25-Sep, Abbott India Ltd. is experiencing a price increase, currently at 30,385.00, reflecting a change of 231.65 (0.77%) upward. Despite this positive movement today, the stock has shown a decline of 1.92% over the past week and 3.60% over the past month, indicating a recent trend of underperformance compared to the broader market. The stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, which suggests a bearish sentiment. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 46.19% against the 5-day average. However, the company boasts a high return on equity (ROE) of 30.11% and a low debt-to-equity ratio, which are positive indicators of management efficiency and financial health.
In the broader market context, Abbott India has outperformed the sector by 1.63% today, even as the benchmark Sensex has declined by 2.23% over the past week. While the stock has generated a return of 6.02% over the past year, the overall market (BSE500) has seen negative returns of -5.88%, highlighting the stock's relative strength. However, concerns about its valuation persist, as it is trading at a premium compared to its peers, with a price-to-book value of 15.3. The flat results reported in June and a high PEG ratio of 2.6 suggest that the stock may be overvalued, which could weigh on future performance despite its current rise.
