PR Sundar revealed that on 19th May, he was carrying Bullish positions (presumably Put shorts). However, this backfired badly because the markets plunged like a stone because of relentless selling by the FIIs.This caused his to suffer a huge MTM loss of Rs. 1 crore.
"It is the worst day of my trading career," he said in a mournful tone.
He also stated that the huge loss had occurred because he had not paid attention to the position sizing and had made many silly mistakes.
"
Even after so many years of experience, have gone wrong in position sizing and made few other silly mistakes, markets have chosen to teach me expensive lesson," he stated.
