The share price of Gome Electrical Appliances doubled in early trading on Tuesday as the company resumed trading after Bain Capital, the US private equity group, confirmed its investment in the leading Chinese retailer.

The stock jumped as much as 107 per cent to HK$2.32 following a seven-month suspension, before retreating to HK$1.90 in the afternoon. Gome’s shares last traded at HK$1.12 on November 24 — the day Huang Guangyu, the former chairman and leading shareholder, came under investigation as part of an alleged share trading scandal.
