MANGOS+
EXCHANGE TRADED NOTES
The MicroSectors™ 3× Long MANGOS+ Ex Private Companies ETNs provides 3x long exposure to the daily performance of the NYSE MaNGoS+ Index, a rules based, equal weighted benchmark of 10 U.S. listed companies at the center of the artificial intelligence economy. A daily-resetting trading tool built for sophisticated investors.
The MANGOS+ ETN
A single daily-resetting tool for magnified long exposure. MNGU seeks a daily return of 3x the daily performance of the NYSE MaNGoS+ Index, before fees and expenses, resetting each trading day.
The underlying index
MNGU references the NYSE MaNGoS+ Index, a rules based, equal weighted benchmark of 10 U.S. listed companies at the center of the artificial intelligence economy.
KNOW THE STRUCTURE
MNGU is designed as a short-term trading tool, not a buy-and-hold investment. Leverage resets daily, so returns over any period longer than one day will differ from three times the return of the NYSE MaNGoS+ Index, and losses compound the same way gains do. A flat or choppy market can produce losses due to the daily reset. The effect increases with index volatility and with the length of the holding period. Investors can lose their entire investment. The ETNs are unsecured debt obligations of Bank of Montreal and do not hold underlying assets, so repayment depends on the creditworthiness of the issuer.
The Index is concentrated. It holds 10 constituents, equally weighted at 10% each on reconstitution, and is reconstituted quarterly. A concentrated basket of this size can be more volatile than a broadly diversified index, and the performance of any single constituent has a material effect on the level of the Index. That concentration is amplified by the 3x leverage factor the notes apply.
How the index is built
The Index is rules based. Six named AI anchors seed the search, disclosed supply chain relationships expand it, and quantitative floors and a continuous AI relatedness score narrow it to 10 names.
Universe
Common stocks, ADRs and GDRs listed on the New York Stock Exchange, Nasdaq, NYSE American, NYSE Arca or Cboe BZX. Publicly traded partnerships, limited partnerships, master limited partnerships and REITs are not eligible. Where a company has multiple qualifying share classes, only the most liquid line is considered.
Eligibility floors
As of the reference date a security must carry a float adjusted market capitalization of $5 billion or more, a six month average daily traded value of $100 million or more, a free float of 5% or more, a positive trailing twelve month price to sales ratio, and at least 60 calendar days of active trading, 14 calendar days for a qualifying ADR whose home market line has traded for at least 365 calendar days, or 5 index business days for a MaNGoS security.
The six anchors
The six named anchors are Meta Platforms Class A (META), Anthropic PBC, NVIDIA (NVDA), Alphabet Class A (GOOGL), OpenAI Group PBC and Space Exploration Technologies Class A (SPCX). Every anchor that meets the qualification requirements is selected for the Index. Anthropic PBC and OpenAI Group PBC are private as of the Index launch date and are therefore ineligible; they seed the supply chain search but can only be included following their listing date if they satisfy the applicable Index eligibility requirement. The lower case letters in MaNGoS denote these two private anchors.
Supply chain map
The non-anchor universe is compiled by identifying the disclosed customers and suppliers of the MaNGoS companies, regardless of whether the anchor itself qualifies for the Index. That means the Index can track companies with supply chain relationships to anchors that are not themselves eligible. All supply chain data is sourced from the FactSet Supply Chain Relationships database.
AI relatedness score
Each non-anchor candidate receives an AI Related Score from 0 to 1, built from its aggregate revenue exposure to Core AI and Enabler AI industries under the FactSet RBICS Level 6 classification. The score equals Core AI revenue exposure plus two thirds of Enabler AI revenue exposure, weighting Core AI 1.5 times Enabler AI. Candidates in a Telecommunications or Real Estate RBICS Focus Level 2 industry are set to 0. A score of 0.20 or greater is required for eligibility.
Selection and weighting
Qualifying anchors are selected first. Current constituents whose combined rank falls inside the top 10 qualifying non-anchor securities are retained next. The highest ranked remaining names then fill the Index to a target count of 10. If too few names qualify, the 0.20 AI Related Score threshold is reduced in 0.01 increments until the target count is met. Every constituent is set to a 10% weight at each quarterly reconstitution and converted to index shares on the share reference date.
Newly listed anchors
A newly listed MaNGoS security can enter between reconstitutions. It is assessed on the ninth business day following listing, announced on the tenth and added after the close on the eleventh, provided it meets the security type, listing, market capitalization, liquidity, free float and price to sales requirements. It replaces the non-anchor constituent with the lowest combined rank, at that constituent’s weight.
The ranking factors
Eligible non anchor candidates are ranked on four factors. A combined rank is derived from the weighted average rank across all four, with ties going to the larger market capitalization.
