币界网报道:Eric Balchunas, senior ETF analyst at Bloomberg, wrote, "Cathie Wood's ARK Invest has just applied for some "structured" ETFs, also known as buffer ETFs. Basically, it is similar to ARKK, but with a 50% decline limit, and the upside (as I understand it) is that except for the initial 5% increase, all other gains can be obtained. In my opinion, this shows that the market demand for products such as "certain income structure" is very strong."
