According to Eric Balchunas, Innovator has filed for an Autocallable Income ETF just one day after Calamos made a similar filing. This rapid succession of filings indicates a growing interest in Autocallable Income ETFs, which are gaining traction among investors seeking structured investment products. Traders should note the potential impact on ETF market liquidity and pricing dynamics. Such products typically offer a predefined income stream and the possibility of early redemption, making them appealing in volatile markets.
