China’s Small-Cap Crash Shows What Happens Without Market Rescue

China’s smallest stocks are flashing a warning about the potential downside for the world’s second-largest equity market if Beijing fails to follow through on a highly anticipated rescue campaign.

While the country’s large-cap CSI 300 Index eked out a 0.7% gain on Monday after a renewed pledge from regulators to support the market, a gauge of small-cap shares sank more than 6% to the lowest level since 2018. That took the CSI 1000 Index’s losses to 27% this year after the measure underperformed larger peers by the most in more than nine years in January.

China's Small Cap Stocks Are Facing Greater Pains

The stark underperformance suggests investors are throwing in the towel on small-cap shares out of belief that policy support will be focused on rescuing blue-chip stocks. Some exchange-traded funds tracking the CSI 300 gauge have seen record trading volume in recent weeks, leading to speculation that state funds have stepped in to put a floor under the rout.

“The market currently relies on support from the national team and investors see the big caps as their buying target,” said Vincent Chan, China strategist at Aletheia Capital Ltd. “This discourages small-cap investors from holding onto their position as they don’t have the downside protection.”

In a sign of how fragile market sentiment has been, the CSI 300 has wiped out all its gains since late last month when policymakers were said to be mulling 2 trillion yuan ($278 billion) of support as part of a stock stabilization fund. Liu Yuhui, an academic at a government think tank, told a local media outlet that the nation should set up a stocks stabilization fund as soon as possible to boost market confidence, with an aim to get its size to 10 trillion yuan or more.
