Tidal Investments implemented a trading halt on the YieldMax MSTR Short Option Income Strategy ETF (WNTR) on February 17, 2026, to address a net asset value calculation error discovered in the fund's pricing methodology. The corrective action resulted in a restatement of the NAV per share downward from $37.8489 to $37.1473, representing an adjustment of approximately 1.9 percent to the fund's stated value.
The fund sponsor identified the calculation discrepancy during a routine valuation review process. The halt was implemented to ensure accurate pricing information was disseminated to shareholders and market participants before resuming normal trading operations. This action reflects standard industry procedures for addressing material pricing errors in exchange-traded funds.
Separately, Tidal Investments also halted trading in the Nicholas Crypto Income ETF (BLOX) during the same period due to a projection error in the fund's calculations. Both halts underscore the importance of fund sponsor oversight mechanisms in identifying and correcting valuation issues that could impact investor positions.
