According to financial reports, on Monday, many funds hit the blockchain hotspots, and many technology ETFs rose considerably. Cathay China Securities ETF, CSI 500 Information Technology ETF, and Invesco Great Wall CSI TMT150ETF both rose more than 5%. According to Huabao Securities, the relative net worth of the Cathay Pacific CSI ETF is estimated to be as high as 2.33%, showing arbitrage opportunities. Insiders suggest that the ETF “special speculation” is more professional. If ordinary investors want to participate, they need to pay attention to the secondary market liquidity of the premium fund and give priority to selecting larger funds.
