Shares of Niu Technologies (NIU) are soaring 5.35% in pre-market trading on Wednesday, following the company's second-quarter earnings call which highlighted robust growth in its home market of China.

The electric scooter manufacturer reported positive results in its Q2 earnings call, with a particular emphasis on strong performance in the Chinese market. This domestic success appears to be driving investor optimism, contributing to the significant pre-market stock price increase.

However, the company also acknowledged challenges in its overseas markets, indicating a mixed global picture for Niu Technologies. Despite these international headwinds, the strong China growth seems to be outweighing concerns, as reflected in the stock's positive movement.
