According to BlockBeats, Eric Balchunas, a senior ETF analyst at Bloomberg, announced on social media that ARK Invest, led by Cathie Wood, has recently filed for structured ETFs, also known as buffered ETFs. These funds are similar to ARKK but feature a 50% downside protection limit. The upside, as understood, allows for gains beyond the initial 5% increase. Balchunas noted that this move indicates a strong market demand for products offering certainty in returns.
