What happened
The MicroSectors FANG+ 3X Leveraged ETN (FNGU) tracks three times the daily performance of an index holding ten large-cap tech stocks—Nvidia, Microsoft, Apple, Amazon, Meta Platforms, Alphabet, Netflix, Broadcom, Palantir, and Micron Technology. The Bank of Montreal called the original FNGU notes in May 2025, launched replacement notes under ticker FNGB, and renamed them back to FNGU in June 2025; the current security therefore did not exist during the 2022 bear market.
Why it matters
The predecessor FNGU lost roughly 87% in 2022 when high-growth tech stocks collapsed, a decline that would require approximately a 669% gain to break even. The ten-stock index is equally weighted (roughly 10% per holding) and concentrated in overlapping themes—artificial intelligence spending, cloud computing, digital advertising, and growth valuations—meaning leverage amplifies losses as well as gains when the group underperforms.
What to watch
FNGU is designed as a daily trading tool, not a buy-and-hold investment; returns over periods longer than one day can differ significantly from three times the index's cumulative performance because leverage resets daily and volatility compounds path-dependently. A $100,000 position would fall to about $13,000 if the current FNGU experienced a similar 87% decline.

FNGU represents a concentrated bet on a small group of expensive, growth-oriented technology leaders amplified by daily leverage. The ten-stock equally weighted index creates a 10% allocation per holding before any leverage is applied; three times daily leverage then scales each stock's economic sensitivity to roughly 30% per rebalance. The body notes that several constituents share overlapping exposures—artificial intelligence spending, cloud computing, digital advertising, and growth-stock valuations—which heightens the risk if the tech/AI theme enters a period of underperformance.
The 2022 precedent is instructive but not directly comparable. The previous FNGU, which followed the same strategy, lost roughly 87% that year; however, the current FNGU is a newly issued security (relaunched in June 2025) and did not experience that decline itself. Nonetheless, the body uses the predecessor's performance to illustrate what three times daily leverage can do in a bear market: a 50% loss requires a 100% gain to recover, but an 87% loss requires approximately a 669% gain—effectively a near-total wipeout of capital. For a $100,000 position, such a decline would leave roughly $13,000.
A critical mechanical risk is daily leverage reset. FNGU does not promise three times whatever the FANG+ Index earns over a month or year; it targets three times the daily return, and leverage resets after every trading session. The body illustrates the erosion: an index that falls 10% and then rises 11.1% returns to its starting point, but a simplified 3X product falls 30% on day one and gains roughly 33.3% from the reduced balance on day two, ending down about 6.7%. Repeated volatility erodes returns even if underlying stocks eventually recover. The Bank of Montreal describes FNGU as a daily trading tool for sophisticated investors rather than a buy-and-hold holding, reflecting this path-dependent compounding risk.
