Hi Nimish,
I am not sure how you have concluded this, but I assume that this is because you have seen high volume on some down bars in recent bars.
Lets assume that there will be an rally on budget. This means that today we are in the last days of accumulation. So we are now expecting that the professionals will have accumulated all the stock and taken a bullish view on the market.To have a successful rally, all the floating supply must have been absorbed by the professionals. But if you have seen high volume in the recent bars, doesn't it mean that there is still floating supply in the market?
One of the "Differential Diagnosis" of such high-volume wide-spread down bars can be "Effort to go down". The stock may be approaching a supportive trend line and the high volume couples with wide spreads may be the efforts to break below that trendline.
