Yesterday when BigCommerce Holdings  (BIGC)  was rocketing, our call was to continue to hold.  Today it added another $34.91 closing at $139.  In the aftermarket it is trading at $135.11.  It is time to take partial profits on another 10% tranche.  The volume is not high in the afterhours and those holding a large quantity will find it difficult to take profits in the afterhours.  It may be better to wait until tomorrow with the full knowledge that with a stock as volatile as this one, there is no telling how it will behave.
