Synopsis: Bitcoin investors have noticed a curious pattern. Prices often rise while they sleep and fall during the day. Now a new ETF wants to profit from this trend.
Nicholas Financial Corporation filed paperwork with the SEC on December 9, 2025. The boutique wealth management firm seeks approval for an unusual bitcoin investment product. The Nicholas Bitcoin and Treasuries AfterDark ETF would hold bitcoin only during overnight hours. Notably, this strategy completely skips U.S. trading sessions.
How the Night-Only Strategy Works
The AfterDark ETF follows a strict daily schedule. The fund buys bitcoin at 4:00 PM Eastern Time when U.S. stock markets close. It then sells all bitcoin positions by 9:30 AM the next morning before markets reopen.
During daytime trading hours, the fund shifts into short-term U.S. Treasuries. This approach preserves capital and generates yield while markets are open. The ETF uses derivatives rather than holding actual bitcoin. Therefore, it gains exposure through futures contracts and bitcoin-linked exchange-traded products.
The fund operates through a Cayman Islands subsidiary for some investments. This structure helps meet tax rules for regulated investment companies. Up to 25% of assets may sit in the offshore entity. On the other hand, the adviser manages this subsidiary without charging additional fees.
Nicholas Financial also filed for a second product called the Nicholas Bitcoin Tail ETF. This companion fund focuses on protecting against sharp bitcoin price drops. However, the AfterDark ETF has drawn more attention for its time-based strategy.
Data Shows Bitcoin’s Overnight Edge
The ETF’s design relies on clear market data. Analytics platform Velo.xyz tracked bitcoin’s performance over the past year. The cryptocurrency tends to gain when U.S. markets are closed. Conversely, it often loses ground during American trading hours.
In fact, bitcoin averaged a 48-basis-point gain overnight from mid-2024 to mid-2025. During the same period, daytime returns averaged negative 2 basis points. Indeed, this pattern creates a significant opportunity for targeted strategies. Bloomberg ETF analyst Eric Balchunas confirmed similar trends for 2024. He noted that spot bitcoin ETFs may influence this behavior. Additionally, derivatives positioning appears to impact intraday volatility. Most of bitcoin’s 2024 gains occurred outside regular U.S. market hours.
November 2025 provided a stark example. Bitcoin dropped roughly 30% that month. Nearly all losses happened during U.S. trading sessions. This mirrors volatility seen in technology stocks during American hours. Furthermore, the data shows bitcoin performing best around 22:00-23:00 UTC. This timing corresponds to late evening in U.S. time zones. Global trading dynamics likely drive these patterns. Ultimately, lower U.S. institutional selling pressure may also play a role.
Investment Structure and Mechanics
The AfterDark ETF maintains at least 80% exposure to bitcoin or Treasuries at all times. The fund uses cash-settled bitcoin futures traded on U.S. exchanges like CME. It also invests in existing spot bitcoin ETFs for indirect price exposure. Exchange-traded options help manage risk and enable smooth position transitions. The fund rotates between assets twice daily around market open and close. This daily rebalancing may lead to high portfolio turnover.
The Commodity Futures Trading Commission classifies the fund as a commodity pool. This designation brings additional regulatory compliance requirements. Thus, the adviser holds registration as a commodity pool operator with the National Futures Association.
Collateral for derivatives includes Treasury bills and money market funds. High-quality commercial paper also backs the fund’s positions. The strategy may use reverse repurchase agreements for added liquidity. Moreover, the ETF employs a sub-adviser to handle Treasury and cash positions. This specialist manages daytime holdings while the main adviser oversees bitcoin exposure. The division of responsibilities aims to optimize each market window.
Risks and Market Outlook
The filing outlines substantial risks for potential investors. Bitcoin’s extreme volatility remains the primary concern. The cryptocurrency has experienced drawdowns exceeding 50% in past cycles. Regulatory changes pose another significant threat. SEC and CFTC policies continue evolving for digital assets. Furthermore, tax treatment of cryptocurrency income faces ongoing scrutiny. The IRS could challenge current rulings on commodity pool income.
Derivatives carry their own set of hazards. Correlation between futures and spot prices may fail. Liquidity issues can arise during market stress. Additionally, counterparty defaults represent a real possibility. The overnight pattern itself may not persist indefinitely. Bitcoin markets continue maturing with increased institutional participation. Nevertheless, Nicholas Financial believes current trends justify the novel approach.
Currently, over a dozen spot bitcoin ETFs trade in the U.S. market. These funds have attracted $57.6 billion in cumulative inflows through December 2025. In contrast, the AfterDark ETF would stand apart with its temporal focus.
SEC approval remains uncertain and could take several months. The agency maintains close scrutiny of cryptocurrency products. However, the filing demonstrates continued innovation in ETF design. It blends quantitative strategies with crypto’s 24/7 global nature.
