Whether its Didi, Alibaba, or Tal Education, Chinese stocks have been slammed this year as Beijing ramps up its regulatory pressure across industries.

The moves sent shockwaves across financial markets, with several high-profile companies like TikTok parent ByteDance postponing their IPO, and US investment managers like Cathie Wood's Ark Invest are rapidly shedding their exposure to Chinese tech stocks.

So far year-to-date, some Chinese stocks listed on US exchanges have fallen more than 90% as regulatory pressures threaten their business models and ability to grow.

Even the electric vehicle sector has been hit this week, with shares of Nio and XPeng both falling more than 10% on Tuesday as investors pare down their exposure to Chinese stocks, despite their strong growth rates and outlook.

The iShares MSCI China ETF has fallen 16% year-to-date and is down 30% from its peak in February. Meanwhile, the S&P 500 is up about 15% year-to-date.

These are the 10 Chinese stocks listed on US exchanges that have seen the biggest year-to-date declines as authorities in Beijing tighten regulation.
