Why is Indo Thai Sec. falling/rising?

As of 23-Oct, Indo Thai Securities Ltd is experiencing a decline in its stock price, currently at 406.00, which reflects a decrease of 21.3 or 4.98%. The stock has been underperforming recently, having fallen consecutively for the last four days, resulting in a total decline of 10.59% over the past week. Today's trading saw the stock open with a loss of 4.05% and reach an intraday low of Rs 405.95. Despite strong performance metrics over the longer term, including a remarkable 306.00% return over the past year and significant growth in operating profit and net sales, the recent drop is compounded by a sharp decline in investor participation, with delivery volume falling by 85.52% against the five-day average.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark Sensex, which has gained 1.30% over the past week. This underperformance relative to the market may be contributing to the stock's decline, as investors may be reacting to the negative short-term trends despite the company's strong fundamentals and consistent returns over the past three years. The increase in institutional investor participation, while a positive sign, has not been sufficient to offset the current downward pressure on the stock price.
