Why is Bengal & Assam falling/rising?

As of 30-Jun, Bengal & Assam Company Ltd is experiencing a decline in its stock price, currently at 8,224.05, which reflects a decrease of 73.95 points or 0.89%. The stock has underperformed its sector by 1.41% today and has seen a trend reversal after four consecutive days of gains. Despite a strong long-term fundamental strength indicated by an average Return on Equity (ROE) of 15.18%, the company has reported poor long-term growth with net sales declining at an annual rate of -28.14% and operating profit falling by -13.29%. The company has declared negative results for the last five consecutive quarters, with net sales in the latest six months showing a significant drop of -76.51%, which has contributed to the recent price movement.
In the broader market context, the stock has outperformed the benchmark Sensex over the past week and month, with returns of +7.52% and +9.43%, respectively, compared to the Sensex's +2.09% and +2.65%. However, year-to-date, the stock has underperformed with a return of -11.57% against the Sensex's +7.00%. The falling investor participation, evidenced by a 91.49% drop in delivery volume, along with the company's expensive valuation and minimal domestic mutual fund holdings, suggests a lack of confidence among investors, further impacting the stock's price negatively.
