Why is Shelter Pharma falling/rising?

As of 03-Sep, Shelter Pharma Ltd is experiencing a decline in its stock price, currently at 45.00, with a change of -0.1, representing a decrease of 0.22%. The stock has underperformed its sector by 1.46% today and has shown erratic trading patterns, having not traded on one day out of the last twenty. Additionally, the stock's delivery volume has fallen significantly, down 37.5% compared to the five-day average, indicating a decrease in investor participation. Over the past week, the stock has decreased by 5.04%, while it has seen a modest increase of 6.13% over the past month. However, year-to-date, it has declined by 19.34%, contrasting with the Sensex, which has gained 3.11%.
In the broader market context, the stock's recent performance is notably weaker than the benchmark, particularly in the short term, where it has underperformed the Sensex by a considerable margin. While the Sensex has shown resilience with a slight decline of only 0.27% over the past week, Shelter Pharma's significant drop highlights its struggles. The stock's moving averages indicate mixed signals, being higher than the 20-day, 50-day, and 100-day averages but lower than the 5-day and 200-day averages, suggesting volatility. Overall, the combination of declining investor interest, erratic trading, and poor performance relative to the benchmark contributes to the stock's downward movement.
