China's AI stock bubble bursts as market value vanishes

The collapse of the STAR50

The mainland STAR50 index, which tracks leaders in the AI and semiconductor sectors, has experienced a dramatic meltdown. According to economictimes.indiatimes.com, the index tanked by 40% in less than four months, vaporizing approximately $480 billion in market value. This sharp reversal marks the end of a two-year rally that began with promises of economic stimulus.

The crash is particularly notable because it occurred while global markets were only experiencing minor fluctuations. While US AI stocks saw a relatively small 6% drawdown from recent highs, the Chinese market saw a much more severe correction. This suggests that the Chinese AI boom was built on much loftier valuations than those found in Western markets.

Market participants describe the previous period as a 'speculative crazy bull' market. Beijing-based fund manager Dong Baozhen noted that the market eventually evolved into this state before the bubble finally burst. The correction has stalled Beijing's efforts to create a 'slow bull' market characterized by reliable, steady performance for savers.

Retail pain and specific losers

The impact of the crash has been felt most acutely by small investors who dominated the recent buying frenzy. Because AI stocks ran to 42% of China's market capitalization, few retail favorites escaped the downward trend. Many investors were emboldened by what they perceived as official support for specific high-growth companies.

Several high-profile companies have seen their valuations slashed in a very short window. For example, shares in the robot-maker Unitree, which was 8,000 times oversubscribed by retail buyers at its listing, have halved since they began trading in August. Similarly, the chipmaker CXMT lost more than a quarter of its value in just one month.

Other tech darlings have faced similar fates following their market debuts. Chipmakers MetaX Integrated Circuits and Moore Threads Technology, which saw massive gains of 700% and 400% respectively last year, have both seen their values halved since July. These losses have left many small business owners and individual investors nursing significant financial hits.

Drivers of the market reversal

While there was no single obvious trigger for the selloff, several factors contributed to the cooling of the market. Traders pointed to excessively high prices and heavy tax bills as primary reasons for the retreat. Additionally, the threat of the US or other nations banning Chinese equipment in data centers created significant uncertainty for investors.

The market is also grappling with the consequences of overemphasizing 'technology content' in major indexes. Leo Wang of Qianchuang Capital explained that the heavy weighting of tech companies by market value led to a distortion in capital behavior. This concentration created a severe bubble in specific sectors while simultaneously causing a serious drain on other parts of the economy.

Furthermore, the crash is affecting the broader investment landscape for Chinese tech firms. Hong Hao of Lotus Asset Management suggested that the current situation will likely put a stop to many companies trying to get themselves listed. This could significantly slow down the ability of new tech ventures to raise equity from the public markets.

Looking ahead at the fallout

The aftermath of the bubble burst is driving a shift in investor behavior toward more defensive assets. Many investors who were previously chasing the AI boom are now looking for lower valuations or moving into different sectors entirely. This shift is expected to dampen the overall momentum of China's efforts to encourage savers to move into stocks.

Despite the crash, some analysts see a path forward for the market. While the STAR50 index is still trading at 100 times trailing earnings, it is down from a peak of nearly 250. Some strategists, including those at BNP Paribas Securities, suggest that the current market conditions may offer buying opportunities for those who are being careful with their approach.

However, many local fund managers remain skeptical about the long-term outlook for these specific manufacturers. Wang Zhuo of Shanghai Zhuozhu Investment Management warned that chipmakers and AI suppliers will eventually face price wars. He noted that 'all bubbles inevitably burst,' suggesting that the era of easy, speculative gains in these sectors has likely concluded.
