Why is Lupin falling/rising?

As of 01-Aug, Lupin Ltd. is experiencing a decline in its stock price, currently at Rs 1,865.45, reflecting a decrease of Rs 59.55 or 3.09%. The stock has been on a downward trend, having fallen for three consecutive days with a total return of -5.98% during this period. It is also trading close to its 52-week low, just 4.9% above that mark. The stock is underperforming against its moving averages, trading lower than the 5-day, 20-day, 50-day, 100-day, and 200-day averages. Despite a healthy long-term growth rate in operating profit and a low debt-to-equity ratio, the recent flat results reported in March and the stock's negative performance over the past month (-5.21%) and year (-4.50%) may be contributing to investor sentiment that is currently bearish.
In the broader market context, Lupin's short-term performance has significantly lagged behind the benchmark Sensex, which has only declined by 1.06% over the past week. The pharmaceuticals and drugs sector, in which Lupin operates, has also seen a decline of 3.27%, indicating sector-wide challenges. While there is rising investor participation with increased delivery volume, the overall market sentiment appears to be cautious, particularly given the stock's recent performance and the flat quarterly results. High institutional holdings may provide some stability, but the current trends suggest that investors are reacting negatively to the company's recent performance metrics.
