Why is Indo Tech.Trans. falling/rising?

As of 22-Sep, Indo Tech Transformers Ltd is experiencing a decline in its stock price, currently at Rs 1,769.25, which reflects a decrease of Rs 47.0 or 2.59%. Today's performance indicates that the stock underperformed its sector by 1.54%, with an intraday low of Rs 1,763, marking a drop of 2.93%. Over the past week, the stock has shown a slight increase of 0.63%, but it has significantly underperformed over the last month with a decline of 4.67%. Despite a strong long-term growth trajectory, with net sales growing at an annual rate of 30.79% and operating profit at 64.35%, the stock's recent performance is overshadowed by the fact that 77.79% of promoter shares are pledged, which adds downward pressure in a falling market.
In the broader market context, the Sensex has increased by 0.46% over the past week, indicating a relatively stable market environment compared to Indo Tech's performance. While the stock has a strong historical return of 701.11% over three years, its year-to-date return is notably negative at -39.04%, contrasting sharply with the Sensex's positive return of 5.15% in the same period. This divergence suggests that investor sentiment towards Indo Tech Transformers Ltd may be influenced by the high percentage of pledged shares, despite the company's healthy financial growth and fair valuation compared to its peers.
