I think Serko's SP weaken so much after the result announced are largely caused by the global markets sell off of tech stocks. Tech stocks around the world have been out of favour in recent months. The "FAANG" + Tecent have really came off the top. Hence, while the SKO result missed fire a bit, traders used it to the fullest and caused a shape pull. Based on the SP movements of SKO after result announcements, the price could still go down a bit, in particular we have all the traders on ASX nowadays.
