(Reuters) - Securities trading and money lending company China Strategic Holdings Ltd said on Tuesday it planned to sell up to a 1.37% stake in a unit of indebted developer China Evergrande Group - and could do so at a significant discount.

China Strategic said in a filing to the Hong Kong stock exchange it would ask shareholders at an extraordinary general meeting to allow directors to dispose of up to 133.6 million shares in China Evergrande New Energy Vehicle Group.

The aspiring electric vehicle maker has a market capitalisaion of HK$28.33 billion ($3.64 billion), according to Refinitiv Eikon data. That indicates a current market value of HK$388 million for a 1.37% stake.

To make any disposals more attractive, however, China Strategic said it would be willing to sell at a 20% discount to the five-day average closing price of Evergrande Vehicle shares. For the five days prior to Tuesday, that works out at around HK$2.76 ($0.35) per share, it added.

Evergrande Vehicle's shares are currently at HK$2.90.

The stock is down more than 90% so far this year as concerns mount across global markets that its parent's $305 billion in debt could trigger widespread losses in China's financial system in the event of a collapse.

"The company acquired the Evergrande Vehicle shares for investment purpose," China Strategic said in the filing.

"Having regard to the recent significant price fluctuations of the Evergrande Vehicle Shares, the board decided to restructure its investment portfolio and to solidify the financial and cash position of the group," it added.
