Shares of Cambricon, often referred to as ‘China’s Nvidia’, have decreased by over 7%. This decline comes amid broader drops in Chinese stock indexes.
This downturn in shares follows reports that Chinese authorities are considering implementing curbs on stock speculation. As a result, Chinese shares have continued to fall in reaction to these developments.
Impacts on the Chinese Market
This news injects significant uncertainty into Chinese markets, which is a key trigger for derivative strategies. The immediate response should be to anticipate higher implied volatility, especially in the tech sector and broader indexes like the FTSE China A50. This environment makes buying options, rather than selling them, a more prudent approach for the coming weeks.
We have seen this pattern before and must act accordingly. During the regulatory crackdowns that began back in 2021, the Hang Seng Tech Index lost over 40% of its value as policy announcements created sustained selling pressure. That period showed us that government directives, even just whispers of them, can override fundamental analysis for months.
Given this, we should consider buying put options on major Chinese ETFs or specific large-cap tech names. The recent jump in open interest for puts on the KraneShares CSI China Internet ETF (KWEB) shows that some traders are already positioning for a downturn, with volumes up nearly 30% in the last week. This strategy offers a clear, risk-defined way to profit if the market follows the historical script of selling off on policy fears.
Volatility and Trading Strategies
Volatility itself is now a tradable asset. We have seen gauges of expected market swings, like the CBOE China ETF Volatility Index (VXFXI), already tick up towards 35, a level that has historically preceded larger market moves. Buying straddles on key indexes would allow us to profit from a significant price swing in either direction, which is likely as the market digests the full impact of any new curbs.
For those with a stronger bearish conviction, shorting index futures on the CSI 300 or Hang Seng is a direct way to play this. The CSI 300 index has already retreated 5% from its August 2025 highs, indicating a fragile market sentiment that is highly susceptible to policy shocks. This kind of directive from authorities is precisely the catalyst that could push the market to retest its yearly lows.
