PANews reported on November 22 that according to Bloomberg, according to documents submitted to the U.S. Securities and Exchange Commission on Wednesday, Calamos Investments is considering launching a so-called "structured protection" ETF that will track part of the returns of Bitcoin while hedging up to 100% of the downside risk through the options market.

The Chicago-based firm filed three strategies this week that will provide full protection over six months, 90% and 80% protection over a year, respectively. Calamos also filed an ETF earlier this year that would provide 100% hedge protection over a year. The ETFs do not currently charge fees and do not list a trading symbol.

Calamos has more than $400 million in assets across 11 structured protection exchange-traded ETFs. The firm, which manages about $40 billion in assets, focuses on options-based strategies across a variety of fund products, including ETFs, separately managed portfolios and mutual funds.
