Miami International Holdings and T3 Index Announce Launch of ConvexityShares ETFs Offering Exposure to SPIKES Volatility Index

PRINCETON, N.J., Aug. 16, 2022 /PRNewswire/ — Miami International Holdings, Inc. (MIH), owner of Miami International Securities Exchange, LLC (MIAX®), MIAX PEARL, LLC (MIAX Pearl®), MIAX Emerald, LLC (MIAX Emerald®), Minneapolis Grain Exchange, LLC (MGEX™) and The Bermuda Stock Exchange (BSX™) and T3 Index today jointly announced the launch of two new ConvexityShares™ exchange traded funds (ETFs) developed to provide investors with access to a new product designed to manage volatility exposure.

ConvexityShares ETFs offer exposure to SPDR® S&P 500® ETF (SPY) volatility and track the SPIKES Futures Short-Term Index (SPKF), which uses input prices of the front two SPIKES® Futures contracts to measure a daily rolling position to provide exposure to the front end of the SPIKES Futures curve. The ConvexityShares ETFs include the ConvexityShares 1x SPIKES Futures ETF (Ticker: SPKX) and the ConvexityShares Daily 1.5x SPIKES Futures ETF (Ticker: SPKY). Each of these ETFs will be listed for trading on NYSE Arca Inc.

“MIAX is pleased to partner with T3 Index to provide a new way to trade volatility,” said Thomas P. Gallagher, Chairman and CEO of MIH. “The launch of ConvexityShares ETFs is an important milestone for the SPIKES Volatility Products franchise, bringing much-needed competition to the marketplace and providing a powerful tool to help market participants manage risk and capitalize on changes in market volatility.”

“MIAX and T3 Index have developed a strong partnership as we developed and launched our portfolio of SPIKES Volatility Products,” said Joseph W. Ferraro III, President of MIAX Futures. “This launch expands our volatility trading ecosystem and showcases our commitment to offer new and innovative products to the trading community.”

The launch of the ConvexityShares ETFs offers traders and investors a new, alternative tool to hedge and capitalize on volatility and is an important enhancement to the current SPIKES® Volatility Products portfolio that T3 and MIAX have jointly created since launching the SPIKES Volatility Index (Ticker: SPIKE) in 2019. The SPIKES index is a measure of the expected 30-day volatility in SPY and the basis for SPIKES Volatility Products.

“In an increasingly volatile and complex market, the launch of ConvexityShares ETFs provides more choice and opportunity in how traders hedge volatility,” said Simon Ho, CEO of T3 Index. “Both the SPIKES Volatility Index and the SPIKES Futures Short-Term Index seek to offer new indexes that are reliable, accurate and an alternative to what’s currently available for volatility traders.”

Important Risk Information

The Funds may be highly volatile and generally are intended for short-term investment purposes only. Investors cannot directly invest in an index.

The funds are commodity pools regulated by the Commodity Futures Trading Commission. These funds are not investment companies regulated under the Investment Company Act of 1940 and are not afforded its protections. Please read the Prospectus carefully before investing.

Shares of the Funds are not insured by the Federal Deposit Insurance Corporation (FDIC), may lose value and have no bank guarantee.

The leveraged ConvexityShares ETF seeks a return that is 1.5x the return of its underlying benchmark (target) for a single day, as measured from one NAV calculation to the next. Due to the compounding of daily returns, holding periods of greater than one day can result in returns that are significantly different than the target return and ConvexityShares’ returns over periods other than one day will likely differ in amount and possibly direction from the target return for the same period.

This information must be preceded or accompanied by a prospectus. We advise you to consider the funds’ objectives, risks, charges and expenses carefully before investing. The prospectus contains this and other important information about the funds. Please read the prospectus carefully before you invest.

The return of the leveraged fund for a period longer than a single day is the result of its return for each day compounded over the period and usually will differ in amount and possibly even direction from the leveraged funds stated goal. These differences can be significant. An investor in any of the funds could potentially lose the full principal value of his/her investment within a single day.

Futures may be affected by Backwardation: a market condition in which a futures price is lower in the distant delivery months than in the near delivery months. As a result, a fund may benefit because it would be selling more expensive contracts and buying less expensive ones on an ongoing basis; and Contango: A condition in which distant delivery prices for futures exceeds spot prices, often due to costs of storing and inuring the underlying commodity. Opposite of backwardation. As a result, a Fund’s total return may be lower than might otherwise be the case because it would be selling less expensive contracts and buying more expensive ones.
