US-listed shares stumble amid capital market turmoil in China

Shares of some United States-listed Chinese companies stumbled on Tuesday as investors appeared to flee anything connected to the turmoil of the mainland's stock market.

"I think that US investors have been bombarded over the last month with the onshore sell-off. They're being sold down because a lot of the US names reflect how US investors view China. The sentiment is very poor right now so they're being sold down," said Brendan Ahern, chief investment officer at Krane Shares, a US-based provider of China-focused exchange-traded funds.

China's benchmark stock market index has now lost more than 30 percent after hitting a peak in mid-June.
