Why is HB Portfolio falling/rising?

As of 17-Sep, HB Portfolio Ltd's stock price is currently at Rs 82.00, reflecting an increase of Rs 5.87, or 7.71%. The stock has shown a strong performance today, outperforming its sector by 7.77% and reaching an intraday high of Rs 88, which is a 15.59% increase. However, despite this positive movement, the stock has experienced a significant decline year-to-date of 22.16% and a one-year decline of 33.24%. The stock has also been highly volatile today, with an intraday volatility of 7.46%. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 72.72% against the 5-day average, indicating a potential concern regarding sustained interest in the stock.
In the broader market context, the stock's short-term return of 5.28% over the past week significantly outperforms the Sensex, which has only increased by 1.56% in the same period. This suggests that while HB Portfolio Ltd is currently experiencing a positive price movement, it has struggled to maintain momentum over a longer timeframe compared to the benchmark. The stock's performance over the last three years shows a substantial gain of 127.78%, contrasting sharply with its year-to-date and one-year declines, highlighting a potential recovery phase despite recent volatility and reduced trading volume.
