Why is Warren Tea falling/rising?

As of 08-Sep, Warren Tea Ltd. is experiencing a price increase, currently at 57.60, reflecting a change of 0.89 or 1.57% upward. The stock has been gaining for the last three days, with a total return of 3.41% during this period, which indicates a positive momentum. However, despite this recent uptick, the stock has underperformed over the past week with a decline of 2.62% compared to the Sensex, which has risen by 0.53%. Additionally, the stock's delivery volume has significantly decreased by 93.63% against the 5-day average, suggesting a drop in investor participation, which could be a concern for sustained growth.
In the broader market context, while Warren Tea has shown a positive return of 4.44% over the past month, it still lags behind the Sensex's 1.16% increase. Year-to-date, the stock is down 1.10%, contrasting with the Sensex's gain of 3.39%. The stock's performance over longer periods is also concerning, with a 20.17% decline over three years compared to the Sensex's 35.35% increase. This disparity indicates that while there may be short-term gains, the overall trend for Warren Tea remains weak relative to the broader market, which could affect investor sentiment moving forward.
