I cannot remember whether the pullback A occured in a similar market condition as the pullback B. But I see them as the same kind of a sharp simple pullback. They both moved from all-time high (high above EMA 9 line) to below EMA100 line, which I believe to be the bottom of the pullback, within 6 trading days.
The volume today, a down day, is above average. I take that as a sign that the smart money absorbed the big sell-off today. If my reading is right, then there will a period of accumulation by the smart money like after the pullback A before the share price starts climbing up again.
But, I think unlikely, if the market conditions worsen, the pullback B will be a reversal.
