Investors seeking to capture Bitcoin's 'night premium' can now access a strategy that rotates out of the asset during U.S. market hours. The Nicholas Bitcoin and Treasuries AfterDark ETF (NGHT) targets the close-to-open gaps that have driven the majority of Bitcoin's performance since the launch of the IBIT spot Bitcoin ETF in January 2024.
According to Bloomberg calculations, cumulative overnight returns since that launch would be approximately +200%, while a simple buy-and-hold strategy returned just over +40%. An inverse strategy—buying at the open and selling at the close—would have returned approximately -50%.
NGHT operates by maintaining long exposure to Bitcoin from 4:00 PM to 9:30 AM New York time through a synthetic structure of Bitcoin futures, Bitcoin-linked ETPs, and options. During the U.S. trading session, the fund rotates its capital into U.S. Treasuries or cash equivalents.
This performance asymmetry is attributed to 'crypto-native' flows in Asia and Europe during U.S. closures, thinner liquidity outside peak U.S. hours, and the tendency of U.S. institutional players to rebalance or take profits during the domestic session.
Capturing this edge comes with significant friction. NGHT carries an expense ratio of 0.97% and faces high turnover transaction costs. The fund's use of derivatives introduces risks related to roll and contango, where rolling long-dated contracts can become costly, as well as counterparty and margin risks.
Previous attempts to capture off-session returns in U.S. equities led to the liquidation of the NightShares 500 ETF (NSPY) and the NightShares 2000 ETF (NIWM) on August 10, 2023, after they struggled to attract assets and failed to outperform benchmarks. The structural complexity of the strategy means the most direct route to Bitcoin exposure without hourly limits remains holding the asset directly.
