Investors seeking to capitalize on the rapid advancements in artificial intelligence now have a new, leveraged trading instrument: the MicroSectors 3× Long MANGOS+ ex Private Companies ETN (NYSE: MNGU). Launched in August by REX Shares and issued by the Bank of Montreal (BMO), the exchange-traded note is designed to provide 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 AI economy.
The significance of this launch lies in its structure and the concentrated nature of the underlying index. Unlike a broad market fund, the MaNGoS+ Index holds just 10 constituents, each equally weighted at 10% and reconstituted quarterly. This concentration means the performance of any single company can materially affect the index, and the 3x leverage amplifies both gains and losses. The index’s six named anchors are major AI players, though private companies like Anthropic and OpenAI are currently ineligible and only seed the supply chain search. The ETN itself only includes common stocks, ADRs, and GDRs listed on major U.S. exchanges.
Crucially, MNGU is a daily-resetting trading tool, not a buy-and-hold investment. Because leverage resets daily, returns over periods longer than one day will differ from three times the index’s return. In choppy, sideways markets, the daily reset mechanism can produce losses even if the index ends flat, and these effects compound with volatility and holding period. This makes MNGU suitable only for sophisticated traders with a short-term bullish view who can monitor their positions throughout the trading day.
The index’s selection process adds another layer of importance. To qualify, anchor companies must meet stringent criteria, including a float-adjusted market cap of at least $5 billion, a six-month average daily traded value of $100 million, and a positive trailing 12-month price-to-sales ratio. The index then targets companies that are customers or suppliers of these anchors, ranking them by AI-related revenue exposure—such as sales of AI-optimized servers, GPUs, cloud AI services, and machine learning platforms. The highest-ranked candidates fill the 10 slots, with the threshold lowered if too few qualify. This methodology aims to capture the evolving leaders of the AI economy, not just the headline names.
For traders looking to express a tactical view on AI trends, MNGU offers a way to gain leveraged exposure to a basket of key companies in one vehicle. However, the risks are substantial: the combination of concentration, leverage, and daily resetting can lead to significant losses. As the AI revolution unfolds at warp speed, instruments like MNGU provide a tool for active traders, but they require a clear understanding of the mechanics and a disciplined, short-term approach.
