A 51-year-old woman investor from Zhejiang province and a keen capital market participant for over a decade, is one of the unlucky ones who saw her fortunes vanish amid the wild market swings.

Jin Jie, who was using an alias as she refused to disclose her real name, said her exposure in the A-share market used to be about 1 million yuan ($161,100). However, the same has now been scaled down to under 500,000 yuan.

"It has been a rock bottom moment for me. Normally, I am a cautious investor and used to have only light positions in the market till June. But when the stock market plunged and the government came out with a series of favorable policies, I increased my exposure and continuously suffered big losses," said Jin.
