Why is Bengal & Assam falling/rising?

As of 29-Jul, Bengal & Assam Company Ltd is experiencing a decline in its stock price, currently at 8,111.00, reflecting a decrease of 50.1 points or 0.61%. The stock has underperformed its sector by 1.07% today and has been on a consecutive downward trend for the last two days, accumulating a total loss of 1.45%. Over the past week, the stock has decreased by 0.75%, and it has shown a significant year-to-date decline of 12.78%. Despite a strong long-term fundamental strength indicated by an average Return on Equity (ROE) of 15.18%, the company has faced poor long-term growth with net sales declining at an annual rate of 28.14% and negative results reported for the last five consecutive quarters, which has negatively impacted investor sentiment.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has seen a slight decline of 1.03% over the past week. While Bengal & Assam's stock has outperformed the benchmark over the three-year and five-year periods, its recent negative results and declining sales have led to a lack of confidence among investors, as evidenced by the minimal stake held by domestic mutual funds at only 0.01%. This suggests that institutional investors may not be comfortable with the current valuation or the business outlook, contributing to the stock's downward movement.
