On Wednesday we brought you the story of Hanergy Thin Solar, formerly the world's largest solar-energy company, and its majority owner, Li Hejun, now the former richest man in China.

Having seen the value of the company soar in recent months, it all came crashing down Wednesday with shares in the company dropping by 47%. It lost Hejun, in paper form at least, about $15 billion.
You'd think a loss of the magnitude wouldn't be repeated anytime soon.
And you'd be wrong.
Earlier Thursday, shares in Goldin Property Holdings Limited, a Hong Kong-listed subsidiary of Goldin Group, collapsed, dropping a whopping 60% upon the resumption of trade. As recently as Wednesday, shares in the company traded as high as $HK29.50. At the lows Friday, $HK9.52, that equates to a net decline of 67.7%.
Goldin Financial Holdings Limited, also a subsidiary of Goldin Group, has also seen its value drop by 67% from Wednesday's highs to Thursday's lows.
Strangely, no announcement has been made by either company, and both continue to trade.
