Funds borrowed via ETF arbitrage halted trading in some stocks, with multiple fund companies warning of risks.

Recently, Haiguang Information plans to absorb and merge Zhongke Dawn, and both companies have suspended trading. A large amount of funds flowed into funds holding a large number of shares in these two companies, and the scale of several thematic ETFs increased significantly. On June 5th, several related ETFs saw a surge in trading volume, reaching a historic high. Faced with the surging arbitrage funds, several fund companies urgently warned of risks. In the view of industry insiders, when market consensus arbitrage expectations heat up, the seemingly "easy money" investment may actually have unpredictable odds of success.
